To J. D. Dana 5 April [1857]
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.

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.

Summary
Thanks JDH for response on variation. Studying variations that seem correlated with environment, e.g., north vs south, ascending mountains.
CD’s weed garden: observations on slugs killing seedlings.
Seed-salting. One-seventh of the plants of any country could be transported 924 miles by sea and would germinate.

To Charles Lyell 13 April [1857]
Summary
CD returns a letter from Wollaston.
Although opposed to the Forbesian doctrine [of continental extension] as a general rule, CD would have no objection to its being proved in some cases. Does not think Wollaston has proved it; nor can anyone until more is known about the means of distribution of insects – but the identity of the two faunas is certainly interesting.
His health is very poor and his "everlasting species-Book" quite overwhelms him with work. It is beyond his powers, but he hopes to live to finish it.
