At Palmer's I was employed in composing for the second edition of Wollaston's "Religion of Nature." Some of his reasonings not appearing to me well founded, I wrote a little metaphysical piece in which I made remarks on them. It was entitled "A Dissertation on Liberty and Necessity, Pleasure and Pain." I inscribed it to my friend Ralph; I printed a small number. It occasion'd my being more consider'd by Mr. Palmer as a young man of some ingenuity, tho' he seriously expostulated with me upon the principles of my pamphlet, which to him appear'd abominable. My printing this pamphlet was another erratum. While I lodg'd in Little Britain, I made an acquaintance with one Wilcox, a bookseller, whose shop was at the next door. He had an immense collection of second-hand books. Circulating libraries were not then in use; but we agreed that, on certain reasonable terms, which I have now forgotten, I might take, read, and return any of his books. This I esteem'd a great advantage, and I made as much use of it as I could. My pamphlet by some means falling into the hands of one Lyons, a surgeon, author of a book entitled "The Infallibility of Human Judgment," it occasioned an acquaintance between us. He took great notice of me, called on me often to converse on those subjects, carried me to the Horns, a pale alehouse in----Lane, Cheapside, and introduced me to Dr. Mandeville, author of the "Fable of the Bees," who had a club there, of which he was the soul, being a most facetious, entertaining companion. Lyons, too, introduced me to Dr. Pemberton, at Batson's Coffee-house, who promis'd to give me an opportunity, sometime or other, of seeing Sir Isaac Newton, of which I was extreamly desirous; but this never happened. I had brought over a few curiosities, among which the principal was a purse made of the asbestos, which purifies by fire. Sir Hans Sloane heard of it, came to see me, and invited me to his house in Bloomsbury Square, where he show'd me all his curiosities, and persuaded me to let him add that to the number, for which he paid me handsomely.
