Summary:
In London for the Botanical Congress; regrets missing CD.
Lyell and CD have mistaken H. Lecoq’s position on glaciers. He has not denied the possibility of a glacial period, only that decreased temperature is needed for their extension.
Recommends F. J. Ruprecht on vegetable detritus in the black earth chernozem of Russia.
