MY CHEMISTRY TUTOR at Cambridge was called A. R. Woresley. He was a middle-aged, shortish man, paunchy, untidily dressed, and with a grey moustache whose edges were stained yellow ochre by the nicotine from his pipe. In appearance, therefore, a typical university don. But he struck me as being exceptionally able. His lectures were never routine. His mind was always darting about in search of the unusual. Once he said to us, “And now we need as it were a tompion to protect the contents of this flask from invading bacteria. I presume you know what a tompion is, Cornelius?”
“I can’t say I do, sir,” I said.
“Can anyone give me a definition of that common English noun?” A. R. Woresley said.
Nobody could.
“Then you’d better look it up,” he said. “It is not my business to teach you elementary English.”
“Oh, come on, sir,” someone said. “Tell us what it means.”
“A tompion,” A. R. Woresley said, “is a small pellet made out of mud and saliva which a bear inserts into his anus before hibernating for the winter, to stop the ants getting in.”
A strange fellow, A. R. Woresley, a mixture of many attitudes, occasionally witty, more often pompous and sombre, but underneath everything there was a curiously complex mind. I began to like him very much after that little tompion episode. We struck up a pleasant studenttutor relationship. I was invited to his house for sherry. He was a bachelor. He lived with his sister, who was called Emmaline of all names. She was dumpy and frowsy and seemed to have something greenish on her teeth that looked like verdigris. She had a kind of surgery in the house where she did things to people’s feet. A pedicurist, I think she called herself.
Then the Great War broke out. It was 1914 and I was nineteen years old. I joined the army. I had to, and for the next four years I concentrated all my efforts on trying to survive. I am not going to talk about my wartime experiences. Trenches, mud, mutilation, and death have no place in these journals. I did my bit. Actually, I did well, and by November 1918, when it all came to an end, I was a twenty-three-year-old captain in the infantry with a Military Cross. I had survived.
At once, I returned to Cambridge to resume my education. The survivors were allowed to do that, though heaven knows there weren’t many of us. A. R. Woresley had also survived. He had remained in Cambridge doing some sort of wartime scientific work and had had a fairly quiet war. Now he was back at his old job of teaching chemistry to undergraduates, and we were pleased to see one another again. Our friendship picked up where it had left off four years before.
One evening in February 1919, in the middle of the Lent term, A. R. Woresley invited me to supper at his house. The meal was not good. We had cheap food and cheap wine, and we had his pedicurist sister with verdigris on her teeth. I would have thought they could have lived in slightly better style than they did, but when I broached this delicate subject rather cautiously to my host, he told me that they were still struggling to pay off the mortgage on the house. After supper, A. R. Woresley and I retired to his study to drink a good bottle of port that I had brought him as a present. It was a Croft 1890, if I remember rightly.
“Don’t often taste stuff like this,” he said. He was very comfortable in an old armchair with his pipe lit and a glass of port in his hand. What a thoroughly decent man he was, I thought. And what a terribly dull life he leads. I decided to liven things up a bit by telling him about my time in Paris six years before in 1913 when I had made one hundred thousand pounds out of Blister Beetle pills. I started at the beginning. Very quickly I got caught up in the fun of story-telling. I remembered everything, but in deference to my tutor, I left out the more salacious details. It took me nearly an hour to tell.
A. R. Woresley was enraptured by the whole escapade. “By gad, Cornelius!” he cried. “What a nerve you’ve got! What a splendid nerve! And now you are a very wealthy young man!”
“Not wealthy enough,” I said. “I want to make a million pounds before I’m thirty.”
“And I believe you will,” he said. “I believe you will. You have a flair for the outrageous. You have a nose for the successful stunt. You have the courage to act swiftly. And what’s more, you are totally unscrupulous. In other words, you have all the qualities of the nouveau riche millionaire.”
“Thank you,” I said.
“Yes, but how many boys of seventeen would have gone all the way out to Khartoum on their own to look for a powder that might not even have existed? Precious few.”
“I wasn’t going to miss a chance like that,” I said.
“You have a great flair, Cornelius. A very great flair. I am envious of you.”
We sat there drinking our port. I was enjoying a small Havana cigar. I had offered one to my host but he preferred his stinking pipe. That pipe of his made more smoke than any other pipe I had ever seen. It was like a miniature warship laying a smokescreen in front of his face. And behind the smokescreen, A. R. Woresley was brooding on my Paris story. He kept snorting and grunting and mumbling things like “Remarkable exploit! . . . What a nerve! . . . What panache! . . . Good chemistry, too, making those pills.”
Then there was silence. The smoke billowed around his head. The glass of port disappeared through the smokescreen as he put it to his lips. Then it reappeared, empty. I had talked enough, so I kept my peace.
“Well, Cornelius,” A. R. Woresley said at last. “You have just given me your confidence. Perhaps I had better give you mine in return.”
He paused. I waited. What’s coming, I wondered.
“You see,” he said. “I myself have also had a little bit of a coup in the last few years.”
“You have?”
“I’m going to write a paper on it when I get the time. And I might even be successful in getting it published.”
“Chemistry?” I asked.
“A bit of chemistry,” he said. “And a good deal of biochemistry. It’s a mixture.”
“I’d love to hear about it.”
“Would you really?” He was longing to tell it.
“Of course.” I poured him another glass of port. “You’ve got plenty of time,” I said, “because we’re going to finish this bottle tonight.”
“Good,” he said. Then he began his story.
“Exactly fourteen years ago,” he said, “in the winter of 1905, I observed a goldfish frozen solid in the ice in my garden pond. Nine days later there was a thaw. The ice melted and the goldfish swam away, apparently none the worse. That set me thinking. A fish is cold-blooded. So what other forms of cold-blooded life could be preserved at low temperatures? Quite a few, I guessed. And from there, I began speculating about preserving bloodless life at low temperatures. By bloodless I mean bacteria, et cetera. Then I said to myself, ‘Who wants to preserve bacteria? Not me.’ So then I asked myself another question. ‘What living organism above all others would you like to see kept alive for very long periods?’ And the answer came back, spermatozoa!”
“Why spermatozoa?” I asked.
“I’m not quite sure why,” he said, “especially as I’m a chemist, not a bio man. But I had a feeling that somehow it would be a valuable contribution. So I started my experiments.”
“What with?” I asked.
“With sperm, of course. Living sperm.”
“Whose?”
“My own.”
In the little silence that followed, I felt a twinge of embarrassment. Whenever someone tells me he has done something, no matter what it is, I simply cannot help conjuring up a vivid picture of the scene. It’s only a flash, but it always happens and I was doing it now. I was looking at scruffy old A. R. Woresley in his lab as he did what he had to do for the sake of his experiments, and I felt embarrassed.
“In the cause of science everything is permissible,” he said, sensing my discomfort.
“Oh, I agree. I absolutely agree.”
“I worked alone,” he said, “and mostly late at night. Nobody knew what I was up to.”
His face disappeared again behind the smokescreen, then swam back into view.
“I won’t recite the hundreds of failed experiments I did,” he said. “I shall speak instead of my successes. I think you may find them interesting. For example, the first important thing I discovered was that exceedingly low temperatures were required to keep spermatozoa alive for any length of time. I kept freezing the semen to lower and still lower temperatures, and with each lowering of the temp I got a longer and longer life span. By using solid carbon dioxide, I was able to freeze my semen down to —97° Centigrade. But even that wasn’t enough. At minus ninetyseven the sperm lived for about a month but no more. ‘I must go lower,’ I told myself. But how could I do that? Then I hit upon a way to freeze the stuff all the way down to —197° Centigrade.”
“Impossible,” I said.
“What do you think I used?”
“I haven’t the foggiest.”
“I used liquid nitrogen. That did it.”
“But liquid nitrogen is tremendously volatile,” I said. “How could you prevent it from vapourizing? What did you store it in?”
“I devised special containers,” he said. “Very strong and rather elaborate vacuum flasks. In these, the nitrogen remained liquid at minus one nine seven degrees virtually forever. A little topping up was required now and again, but that was all.”
“Not forever, surely.”
“Oh, yes,” he said. “You are forgetting that nitrogen is a gas. If you liquefy a gas, it will stay liquid for a thousand years if you don’t allow it to vapourize. And you do this simply by making sure that the flask is completely sealed and efficiently insulated.”
“I see. And the sperm stayed alive?”
“Yes and no,” he said. “They stayed alive long enough to tell me I’d got the right temperature. But they did not stay alive indefinitely. There was still something wrong. I pondered this and in the end I decided that what the sperm needed was some sort of a buffer, an overcoat if you like, to cushion them from the intense cold. And after experimenting with about eighty different substances, I at last hit on the perfect one.”
“What was it?”
“Glycerol.”
“Just plain glycerol?”
“Yes. But even that didn’t work at first. It didn’t work properly until I also discovered that the cooling process must be done very gradually. Spermatozoa are delicate little fellows. They don’t like shocks. You cause them distress if you subject them straightaway to minus one nine seven degrees.”
“So you cooled them gradually?”
“Exactly. Here is what you must do. You mix the sperm with the glycerol and put it in a small rubber container. A test tube is no good. It would crack at low temperatures. And by the way, you must do all this as soon as the sperm has been obtained. You must hurry. You cannot hang about or it will die. So first you put your precious package on ordinary ice to reduce the temperature to freezing point. Next, you put it into nitrogen vapour to freeze it deeper. Finally you pop it into the deepest freeze of all, liquid nitrogen. It’s a step by step process. You acclimatize the sperm gradually to coldness.”
“And it works?”
“Oh, it works all right. I am quite certain that sperm which has been protected with glycerol and then frozen slowly will stay alive at minus one nine seven for as long as you like.”
“For a hundred years?”
“Absolutely, provided you keep it at minus one nine seven degrees.”
“And you could thaw it out after that time and it would fertilize a woman?”
“I’m quite sure of it. But having got that far I began to lose interest in the human aspect. I wanted to go a lot further. I had many more experiments to do. But one cannot experiment with men and women, not in the way I wanted to.”
“How did you want to experiment?”
“I wanted to find out how much sperm wastage there was in a single ejaculation.”
“I’m not with you. What d’you mean by sperm wastage?”
“The average ejaculation from a large animal such as a bull or a horse produces five cc’s of semen. Each cc contains one thousand million separate spermatozoa. This means five thousand million sperm all together.”
“Not five thousand million! Not in one go!”
“That’s what I said.”
“It’s unbelievable.”
“It’s true.”
“How much does a human produce?”
“About half that. About two cc’s and two thousand million.”
“You mean to tell me,” I said, “that every time I pleasure a young lady, I shoot into her two thousand million spermatozoa?”
“Absolutely.”
“All squiggling and squirming and thrashing about?”
“Of course.”
“No wonder it gives her a charge,” I said.
A. R. Woresley was not interested in that aspect. “The point is this,” he said. “A bull, for example, definitely does not need five thousand million spermatozoa in order to achieve fertilization with a cow. Ultimately, he needs only a single sperm. But in order to make sure of hitting the target, he has to use a few million at least. But how many million? That was my next question.”
“Why?” I asked.
“Because, my dear fellow, I wanted to find out just how many females, whether they were cows, mares, humans, or whatever, could ultimately be fertilized by a single ejaculation. I was assuming, of course, that all those millions of sperm could be divided up and shared among them. Do you see what I’m driving at?”
“Perfectly. What animals did you use for these experiments?”
“Bulls and cows,” A. R. Woresley said. “I have a brother who owns a small dairy farm over at Steeple Bumpstead not far from here. He had a bull and about eighty cows. We had always been good friends, my brother and I. So I confided in him, and he agreed to let me use his animals. After all, I wasn’t going to hurt them. I might even do him a favour.”
“How could you do him a favour?”
“My brother has never been well off. His own bull, the only one he could afford, was of moderate quality. He would dearly love to have had his whole herd of cows bear calves by a splendid prize bull from very high milkyielding stock.”
“You mean someone else’s bull?”
“Yes, I do.”
“How would you go about obtaining semen from someone else’s valuable bull?”
“I would steal it.”
“Ah-ha.”
“I would steal one ejaculation, and then, provided of course that I was successful with my experiments, I would share out that single ejaculation, those five thousand million sperm, among all of my brother’s eighty cows.”
“How would you share it out?” I asked.
“By what I call hypodermic insemination. By injecting the sperm into the cow with a syringe.”
“I suppose that’s possible.”
“Of course it’s possible,” he said. “After all, the male sexual organ is itself really nothing more than a syringe for injecting semen.”
“Steady on,” I said. “Mine’s a bit more than that.”
“I don’t doubt it, Cornelius, I don’t doubt it,” he answered dryly. “But shall we stick to the point?”
“Sorry.”
“So I started experimenting with bulls’ semen.”
I picked up the bottle of port and refilled his glass. I had the feeling now that old Woresley was onto something pretty interesting and I wanted to keep him going.
“I’ve told you,” he said, “that the average bull produces about five cc’s of fluid each time. That’s not much. Even when mixed with glycerol there wouldn’t be enough there for me to start dividing it up into a great many parts and then expect to be able to inject each of those tiny parts into separate cows. So I had to find a dilutant, something to increase the volume.”
“Why not add more glycerol?”
“I tried it. It didn’t work. Altogether too viscous. I won’t bore you with a list of all the curious substances I experimented with. I will simply tell you the one that works. Skimmed milk works. Eighty per cent skimmed milk, ten per cent egg yolk, and ten per cent glycerol. That’s the magic mixture. The sperm love it. You simply mix the whole cocktail thoroughly, and that, as you can see, gave me a practical volume of fluid to experiment with. So for several years, I worked with my brother’s cows, and finally I arrived at the optimum dose.”
“What was it?”
“The optimum dose was no more than twenty million spermatozoa per cow. When I injected that into a cow at the right time, I got eighty per cent pregnancies. And don’t forget, Cornelius,” he went on excitedly, “that each bull’s ejaculation contains five thousand million sperm. Divided up into doses of twenty million, that gives two hundred and fifty separate doses! It was amazing! I was flabbergasted!”
“Does that mean,” I said, “that with just one of my own ejaculations I could make two hundred and fifty women pregnant?”
“You are not a bull, Cornelius, much as you may like to think you are.”
“How many females could one of my ejaculations do?”
“About a hundred. But I am not about to help you.”
By God, I thought, I could knock up about seven hundred women a week at that rate! “Have you actually proved this with your brother’s bull?” I asked.
“Many times,” A. R. Woresley said. “It works. I collect one ejaculation, then I quickly mix it up with skimmed milk, egg yolk, and glycerol, then I measure it into single doses before freezing.”
“What volume of fluid in each dose?” I asked.
“Very small. Just half a cc.”
“Is that all you inject into the cow, just half a cc of fluid?”
“That’s all. But don’t forget there’s twenty million living spermatozoa in that half cc.”
“Ah, yes.”
“I put these little doses separately into small rubber tubes,” he said. “I call them straws. I seal both ends, then I freeze. Just think of it, Cornelius! Two hundred and fifty highly potent straws of spermatozoa from a single ejaculation!”
“I am thinking about it,” I said. “It’s a bloody miracle.”
“And I can store them for as long as I like, deep frozen. All I have to do when a cow starts bulling is take out one straw from the liquid nitrogen flask, thaw it, which doesn’t take a minute, transfer the contents to a syringe, and shoot it into the cow.”
The bottle of port was three-quarters empty now and A. R. Woresley was getting a bit tipsy. I refilled his glass again.
“What about this prize bull you were talking about?” I said.
“I’m coming to that, my boy. That’s the lovely part of the whole thing. That’s the dividend.”
“Tell me.”
“Of course I’ll tell you. So I said to my brother—this was three years ago, right in the middle of the war; my brother was exempt from the army, you see, because he was a farmer—so I said to Ernest, ‘Ernest,’ I said, ‘if you had the choice of any bull in England to service your entire herd, which one would you choose?’
“‘I don’t know about in England,’ Ernest said, ‘but the finest bull in these parts is Champion Glory of Friesland, owned by Lord Somerton. He’s a purebred Friesian, and those Friesians are the best milk producers in the world. My God, Arthur,’ he said, ‘you should see that bull! He’s a giant! He cost ten thousand pounds and every calf he gets turns out to be a tremendous milker!’
“‘Where is this bull kept?’ I asked my brother.
“‘On Lord Somerton’s estate. That’s over in Birdbrook.’
“‘Birdbrook? That’s quite close, isn’t it?’
“‘Three miles away,’ my brother said. ‘They’ve got around two hundred pedigree Friesian dairy cattle and the bull runs with the herd. He’s beautiful, Arthur, he really is.’
“‘Right,’ I said. ‘In the next twelve months, eighty per cent of your cows are going to have calves by that bull. Would you like that?’
“‘Like it!’ my brother said. ‘It would double my milk yield.’ Could I trouble you, my dear Cornelius, for one last glass of your excellent port?”
I gave him what there was. I even gave him the lees in the bottom of the bottle. “Tell me what you did,” I said.
“We waited until one of my brother’s cows was bulling good and proper. Then, in the dead of night—this took courage, Cornelius, it took a lot of courage . . .”
“I’m sure it did.”
“In the dead of night, Ernest put a halter on the cow and he led her along the country lanes to Lord Somerton’s place three miles away.”
“Didn’t you go with them?”
“I went beside them on a bicycle.”
“Why the bicycle?”
“You’ll see in a moment. It was the month of May, nice and warm, and the time was around one in the morning. There was a bit of a moon shining, which made it more dangerous, but we had to have some light to do what we were going to do. The journey took us an hour.
“‘There you are,’ my brother said. ‘Over there. Can you see them?’
“We were by a gate leading into a twenty-acre field and in the moonlight I could see the great herd of Friesians grazing all over the field. To one side, not far away, was the big house itself, Somerton Hall. There was a single light in one of the upstairs windows. ‘Where’s the bull?’ I said.
“‘He’ll be in there somewhere,’ my brother said. ‘He’s with the herd.’
“Our cow,” A. R. Woresley said to me, “was mooing away like mad. They always do when they’re bulling. They’re calling the bull, you see. The gate into the field was padlocked with a chain, but my brother was ready for that. He pulled out a hacksaw and sawed through the chain. He opened the gate. I leaned my bike against the hedge and we went into the field, leading the cow. The field was milky white in the moonlight. Our cow, sensing the presence of other animals, began mooing louder than ever.”
“Were you frightened?” I asked.
“Terrified,” A. R. Woresley said. “I am a quiet man, Cornelius. I lead a quiet life. I am not cut out for escapades like this. Every second I expected to see his lordship’s bailiff come running toward us with a shotgun in his hands. But I forced myself to keep going because this thing we were doing was in the cause of science. Also, I had an obligation to my brother. He had helped me greatly. Now I must help him.”
The pipe had gone out. A. R. Woresley began to refill it from a tin of cheap tobacco.
“Go on,” I said.
“The bull must have heard our cow calling to him. ‘There he is!’ my brother cried. ‘Here he comes!’
“A massive white and black creature had detached himself from the herd and was trotting our way. He had a pair of short sharp horns on his head. Lethal, they looked. ‘Get ready!’ my brother snapped. ‘He won’t wait! He’ll go right at her! Give me the rubber bag! Quick!’”
“What rubber bag?” I said to Woresley.
“The semen collector, my dear boy. My own invention, an elongated bag with thick rubber lips, a kind of false vagina. Very effective too. But let me go on.”
“Go on,” I said.
“‘Where’s the bag?’ my brother shouted. ‘Hurry up, man!’ I was carrying the thing in a knapsack. I got it out and handed it to my brother. He took up his station near the cow’s rear and to one side. I stood on the other side, ready to do my bit. I was so frightened, Cornelius, I was sweating all over and I kept wanting to urinate. I was frightened of the bull and I was frightened of that light in the window of Somerton Hall behind me, but I stood my ground.
“The bull came trotting up, snorting and dribbling. I could see a brass ring in his nose, and by God, Cornelius, he was a dangerous-looking brute. He didn’t hesitate. He knew his business. He took one sniff at our cow, then he reared up and thrust his front legs onto the cow’s back. I crouched alongside him. His pizzle was coming out now. He had a gigantic scrotum and just above it this incredible pizzle was getting longer and longer. It was like a telescope. It started quite short and very quickly it got longer and longer until it was as long as my arm. But not very thick. About as thick as a walking-stick, I’d say. I made a grab for it but in my excitement I missed it. ‘Quick!’ my brother said. ‘Where is it? Get hold of it quick!’ But it was too late. The old bull was an expert marksman. He’d hit the target first time and the end of his pizzle was already inside the cow. It was halfway in. ‘Get it!’ my brother shouted. I grabbed for it again. There was still quite a bit of it showing. I got both hands on it and pulled. It was alive and throbbing and slightly slimy. It was like pulling on a snake. The bull was thrusting it in and I was pulling it out. I pulled so hard on it I felt it bend. But I kept my head and started synchronizing my pulls with the animal’s backward movements. Do you see what I mean? He would thrust forward, then he would have to arch his back before going forward again. Each time he arched his back, I gave a pull and gained a few inches. Then the bull thrust forward and in it went once more. But I was gaining on him and in the end, using both hands, I managed to bend it almost double and flip it out. The end of it whacked me across the cheek. That hurt. But quickly I jammed it into the bag my brother was holding. The bull was still bashing away. He was totally absorbed in his work. Thank God he was. He didn’t even seem to be aware of our presence. But the pizzle was in the bag now and my brother was holding it and in less than a minute it was all over. The bull lurched backwards off the cow. And then suddenly he saw us. He stood there staring at us. He seemed a bit perplexed, and who could blame him. He gave a deep bellow and started pawing the ground with his front legs. He was going to charge. But my brother, who knew about bulls, walked straight up to him and slapped him across the nose. ‘Git away!’ he said. The bull turned and ambled back toward the herd. We hurried out through the gate, closing it behind us. I took the rubber bag from my brother and jumped onto the bicycle and rode hell for leather back to the farm. I made it in fifteen minutes.
“At the farm I had everything ready. I scooped out the bull’s semen from the bag and mixed it with my special solution of milk, egg yolk, and glycerol. I filled two hundred and fifty of my little rubber straws with half a cc each. This was not as difficult as it sounds. I always have the straws lined up in rows on a metal rack and I use an eye dropper. I transferred the rack of filled straws onto ice for half an hour. Then I lifted it into a container of nitrogen vapour for ten minutes. Finally, I lowered it into a second vacuum container of liquid nitrogen. The whole process was finished before my brother arrived back with the cow. I now had enough semen from a prize Friesian bull to fertilize two hundred and fifty cows. At least I hoped I had.”
“Did it work?” I asked.
“It worked fantastically,” A. R. Woresley said. “The following year my brother’s Hereford cattle began producing calves that were one-half Friesian. I had taught him how to do the hypodermic insemination himself, and I left the canister of frozen “straws” with him on the farm. Today, my dear Cornelius, three years later, nearly every cow in his herd is a cross between a Hereford and a prize Friesian. His milk yield is up by something like sixty per cent and he has sold his bull. The only trouble is that he’s running out of straws. He wants me to go with him on another of those dangerous journeys to Lord Somerton’s bull. Quite frankly, I dread it.”
“I’ll go,” I said. “I’ll take your place.”
“You wouldn’t know what to do.”
“Just grab the old pizzle and bung it in the bag,” I said. “You can be waiting back at the farm all ready to freeze the semen.”
“Can you manage a bicycle?”
“I’ll take my car,” I said. “Twice as quick.”
I had just bought a brand new Continental Morris Cowley, a machine superior in every way to the 1912 De Dion of my Paris days. The body was chocolate brown. The upholstery was leather. It had nickel fittings, mahogany cappings, and a driver’s door. I was very proud of it. “I’ll get the semen back to you in no time,” I said.
“What a splendid idea,” he said. “Would you really do that for me, Cornelius?”
“I’d love to,” I said.
I left him soon after that and drove back to Trinity. My brain was humming with all the things A. R. Woresley had told me. There was little doubt he had made a tremendous discovery, and when he published his findings he would be hailed all over the world as a great man. He was probably a genius.
But that didn’t bother me one way or the other. What did concern me was this: How could I myself make a million pounds out of it all? I had no objection to A. R. Woresley’s getting rich at the same time. He discovered it. But yours truly came first. The more I thought about it, the more convinced I became that there was a fortune waiting for me just around the corner. But I doubted it was from bulls and cows.
I lay awake in bed that night and applied my mind assiduously to this problem. I may seem, to a reader of these diaries, like a pretty casual sort of fellow where most things are concerned, but I promise you that when my own most important interests are at stake I am capable of some very concentrated thinking. Somewhere around midnight an idea came to me and began whizzing around in my head. It appealed to me at once, this idea, for the simple reason that it involved the two things in life that I found most entertaining—seduction and copulation. It appealed to me even more when I realized that it involved a tremendous amount of seduction and copulation.
I got out of bed and put on my dressing-gown. I began making notes. I examined the problems that would arise. I thought up ways of overcoming them. And at the end of it all I came to the very definite conclusion that the scheme would work. It was bound to work.
There was only one snag. A. R. Woresley had to be persuaded to go along with it.
