1663, Hudibras, by Samuel Butler, part 1,Quoth Hudibras, I smell a rat; Ralpho, thou dost prevaricate: For though the thesis which thou lay'st Be true, ad amussim, as thou say'st; For that bear-baiting should appear, Jure divino, lawfuller Than synods are, thou dost deny Totidem verbis; so do I: Yet there's a fallacy in this; For if by sly homœosis, Thou wouldst sophistically imply Both are unlawful, I deny.
