I observe, first, the facetiousness of your title-page, “_Due correction for Mr. Hobbes, or School Discipline, for not saying his Lessons right_.” What a quibble is this upon the word lesson; besides, you know it has taken wind; for you vented it amongst your acquaintance at Oxford then when my _Lessons_ were but upon the press. Do you think if you had pretermitted that piece of wit, the opinion of your judgment would have been ere the less? But you were not content with this, but must make this metaphor from the rod to take up a considerable part of your book, in which there is scarce anything that yourself can think wittily said besides it. Consider also these words of yours: “_It is to be hoped that in time you may come to learn the language, for you be come to great_ A _already_.” And presently after, “_were I great_ A, _before I would be willing to be so used, I should wish myself little_ a _a hundred times_.” Sir, you are a doctor of divinity and a professor of geometry, but do not deceive yourself, this does not pass for wit in these parts, no, nor generally at Oxford; I have acquaintance there that will blush at the reading it. Again, in another place you have these words: “_Then you catechize us_, ‘_what is your name? Are you geometricians? Who gave you that name_,’” &c. Besides in other places such abundance of the like insipid conceits, as would make men think, if they were no otherwise acquainted with the University but by reading your books, that the dearth there of salt were very great. If you have any passage more like to salt than these are (excepting _now and anon_) you may do well to show it to your acquaintance, lest they despise you; for, since the detection of your geometry, you have nothing left you else to defend you from contempt. But I pass over this kind of eloquence, and come to somewhat yet more rural. Page 27, line 1, you say I have given Euclid his _lurry_. And again, page 129, line 11, “_and now he is left to learn his lurry_.” I understand not the word _lurry_. I never read it before, nor heard it, as I remember, but once, and that was when a clown threatening another clown said he would give him _such a lurry come poop_, &c. Such words as these do not become a learned mouth, much less are fit to be registered in the public writings of a doctor of divinity. In another place you have these words, “_just the same to a cow’s thumb_,” a pretty adage. Page 2, “_But prithee tell me_.” And again, page 95, “_prithee tell me, why dost thou ask me such a question_,” and the like in many other places.
