London, May 28, 1799
DEAR SIR,
I HAVE onl; time to say, I have sent you a sort of preface to Colonel Blackader. While writing I was led into a train of which I had no thought when I began. Such as it is, if you like it — well — if not, suppress it, and get some one at Edinburgh to write another. There are many good writers among your acquaintance. I find at the age of 74 I cannot do as formerly; but I am as much as ever, and I hope I always shall be, Your affectionate and obliged,
J. N.
