Edinburgh: 1854. unbound. 3 pages (front and back) each measuring 7.25 x 4.5 inches, Edinburgh, October 6, 1854 -- a chatty letter to a colleague, in small part: "...Mr. Watson has presented himself and your letter, and I am in no doubt of adding him as an acceptable addition to our corps of literary priests in Edinburgh, since he has appeared at your Tuesday evening meetings. I shall introduce him to one or two friends." Faint staining, but still in very good condition.
Scottish geologist and evolutionary thinker who authored the anonymous book "Vestiges of the Natural History of Creation" in 1844, fifteen years before Darwin published "On the Origin of Species."
