"A Grocer of good business desires an Apprentice of good growth." The "good growth" must have been intended to convey the idea of height and strength. My next article shall be devoted to advertisements of another class, further illustrating the state of society and the peculiarities of the people at the end of the seventeenth century. H. M. BEALBY. North Brixton. TREATISE OF EQUIVOCATION. As having originated the inquiry in "NOTES AND QUERIES"[1] respecting this Treatise, under the signature of J. M., I feel great obligation both to the editor of that journal, and the editor of the Treatise itself, for having brought it to light by publication, and added it to the stock of accurate and very important historical information. Indeed, a real vacancy was left for it; and it is a subject of high self-gratulation, that a boon previously, and for a length of time, hidden and unproductive, is now accessible and operative without limit. I have no doubt that all your readers, and the whole reading public, join with me in rejoicing that the editorship of the work has fallen into hands so competent and so successful. [Footnote 1: Vol. i., pp. 263. 357.; Vol. ii., pp. 136. 168. 446. 490.] I was, not for ten, but twenty years or more, in quest of the MS. now so happily made public property, and should have fallen upon it much earlier, but for the misleading title under which it appears, where it _is_ really; for it has been found. In the _Catalogus Lib. MSS._: Ox. 1697, among the Laudian MSS. appears, p. 62., "968.95. _A Treatise_ against _Equivocation, or fraudulent Dissimulation_." _Against!_ when no such word is in the original, and the real matter and meaning is _for_! I had, at some early time, marked the very entry; but presuming that the work had been actually _printed_ (which I believe it was in a very few copies, which have disappeared), naturally enough I did not pursue the search in that direction. Others, I am happy, have, and I am gratified.
