15 Ditto: Pope took great pride in the decasyllabic nature of his rhyming couplets. This is one of only two feminine endings in the whole (over 1,500 line) poem, the other being a rhyme of ‘silly’ with ‘Sir Billy’: it seems it was acceptable to Pope so long as the rhyming words were proper names. Maybe here he hears Cowards as Cards and Howards as Hards…
