Encourages CSB to do research on the complemental males of Scalpellum vulgare.

Summary

If JM disapproves of inserting CD’s geological works on back of title-page [of Origin, 3d ed.], he should strike them out. CD cares little. Reminds him to insert "additions and corrections" in advertisements. Sends list for presentation copies.
