Summary:
Is glad he likes the idea of projecting more than a hemisphere. Compares his own projection and a stereoscopic projection and comments on the results. Is now having another projection made that should give an accurate map of America.

Summary:
Asks whether Crustacea from temperate parts of the Southern Hemisphere are more strongly analogous to those in same latitudes of the Northern Hemisphere than are Arctic to Antarctic Crustacea.
Discusses astonishing finds of mammalian and reptilian remains in Purbeck beds; notes reactions of Lyell.
Has doubts about Richard Owen’s recent classification of mammals [J. Proc. Linn. Soc. Lond. (Zool.) 2 (1858): 1–37].
Works away [on Natural selection].
Asa Gray has given valuable assistance.
