“I have been long out of the world by deafness and extreme old age. I hope, however, if we should not meet again in this world, that we shall meet and renew our acquaintance in another. In the mean time, I am with great esteem, dear sir, yours affectionately, “THO. REID. “_Glasgow College_, ”_12th April, 1792_.” This curious letter I published in the Ed. Phil. Journal for October 1, 1820. It excited the particular attention of the late George Chalmers, Esq., who sent me an elaborate letter upon the subject; but as I was at that time in the expectation of obtaining some important information through other channels, this letter was not published. This hope, however, has been disappointed. A careful search has been made through the charter-chest of the Newtons of Newton in East Lothian, by Mr. Richard Hay Newton, the representative of that family, but no document whatever has been found that can throw the least light upon the matter. It deserves to be remarked, however, that Sir Richard Newton, the alleged correspondent of Sir Isaac, appears to have destroyed his correspondence; for though the charter-chest contains the letters of his predecessors for some generations, yet there is not a single epistolary document either of his own or of his lady’s. Hitherto the evidence of Sir Isaac’s Scottish descent has been derived chiefly from his conversation with Mr. James Gregory; but I am enabled, by the kindness of Mr. Robison, to corroborate this evidence by the following information, derived, as will be seen, from the family of the Newtons of Newton. Among various memoranda in the handwriting of Professor Robison, who at one time proposed to write the life of Sir Isaac, are the following:— “1st, Lord Henderland informed me in a letter dated March, 1794, that he had heard from his infancy that Sir Isaac considered himself as descended from the family of Newton of Newton. This he heard from his uncle Richard Newton of Newton (who was third son of Lord William Hay of Newhall):” “He said that Sir Isaac wrote to Scotland to learn whether any descendants of that family remained, and this (it was thought) with the view to leave some of his fortune to the family possessing the estate with the title of baronet. Mr. Newton, not having this honour, and being a shy man, did not encourage the correspondence, because he did not consider _himself_ as of kin to Sir Isaac, &c.” “2d, Information communicated to me by Hay Newton, Esq., of that ilk, 18th August, 1800.”
