THE REV. JOHN LAWSON AND HIS MATHEMATICAL MANUSCRIPTS.

In the year 1774 the Rev. John Lawson, B.D., Rector of Swanscombe in Kent, published A Dissertation on the Geometrical Analysis of the Antients, with a Collection of Theorems and Problems without solutions for the Exercise of young Students. This work was printed anonymously at Canterbury, but the merits of the essay did not permit the author to remain long in obscurity; the real writer was immediately known to most of the geometers of the day, and the elegant character of many of the theorems and problems, led to a general desire that their solutions should be published in a separate work. In accordance with this intention, it was announced on a fly-sheet attached to some copies of the work, that—

"The author of this publication being a man of leisure, and living in a retired situation, remote from any opportunity of conversation with mathematicians, would be extremely glad of a correspondence with any such, who are willing to be at the expense of the same; or if this be thought too much, will pay the postage of his answers to their letters. But no letters, except post-paid, can be received by him; otherwise a door would be opened for frolic, imposition, and impertinence. Any new geometrical propositions, either theorems or problems, would be received with gratitude, and if sent without solutions, he would use his best endeavours to return such as might be satisfactory. Any new solutions of propositions already in print, especially of those included in the present collection, would also be very agreeable. If a variety of such demonstrations essentially different from those of the original authors should be communicated, he proposes at some future time to publish them all, with a fresh collection for further exercise; and then each author's name shall be affixt to his own solution, or any other signature which he shall please to direct. Any person who shall favor the publisher with his correspondence shall have speedily conveyed to him the solutions of any propositions contained in this collection, which he may be desirous of seeing. Letters (post-paid) directed for P. Q., to be left at Mr. Nourse's, Bookseller, in the Strand, London, will be carefully transmitted on the first day of each month, and all correspondents may expect answers during the course of that month."

In consequence of this appeal, Mr. Lawson was speedily in correspondence with several of the most able geometers then living, and amongst the rest, Messrs. Ainsworth, Clarke, Merrit, Power, &c., appear to have furnished him with original solutions to his collection of theorems and problems. The manuscript containing these solutions must have been of considerable size, since a portion of it was sent down to Manchester about July, 1777, for the purpose of obtaining Mr. Ainsworth's remarks and corrections; and Mr. Lawson is requested, in a letter bearing date "August 22, 1777," to "send the next portion when convenient." Whether Mr. Lawson did so or not, I have not yet been able to ascertain; but this much is certain, the manuscript was never printed, and would most probably either be disposed of at the death of its compiler, or previously transferred to the possession of some geometer of Mr. Lawson's acquaintance. Several of the original letters which passed between the respective parties relating to this manuscript are at present in the hands of two or three of the Lancashire geometers, but no one seems to know anything of the manuscript itself. May I then request that the fortunate holder of this yet valuable collection will make himself known through the medium of the widely circulated pages of "N. & Q."

"Wanderings of Memory."—In Brayley's Graphic and Historical Illustrator, p. 293., is a quotation from the Wanderings of Memory, as a motto to an account of the ancient castle of the Peverils at Castleton, in Derbyshire: can any of your readers tell me who was the author of the poem in question?
