P.S. You showed me one or two new volumes on geology ^in Salem & if you should not take them to Nantucket & would send them to me for a few weeks along with Bouvé’s Journal of which you speak, I should be greatly indebted. Have you any thing recent on the subject of the Deluge? I am about writing on that subject for the Quarterly Observer. You can send me a packet probably by leaving it at the bookstore where the Christian Spectator or Journal of Science are printed. Let me know of any expense you have incurred.
