June 2, 1725.
Sir,
Having lately been in the northern parts of America, I have brought from thence a purse made of the asbestos, a piece of the stone, and a piece of the wood, the pithy part of which is of the same nature, and called by the inhabitants salamander cotton. As you are noted to be a lover of curiosities, I have informed you of these: and if you have any inclination to purchase or see them, let me know your pleasure, by a line directed for me at the Golden Fan in Little Britain, and I will wait upon you with them.
I am, sir,
Your most humble servant,
B. FRANKLIN.
P. S. I expect to be out of town in two or three days, and therefore beg an immediate answer.
