"Frank has sent the cards here."
Thanks for ESM’s address ["What American zoologists have done for evolution", Proc. Am. Assoc. Adv. Sci. 25 (1876)].
J. A. Allen’s work is important as apparently showing change through direct action of [external] conditions.
CD has given up trying to understand E. D. Cope and Alpheus Hyatt on acceleration and retardation.
Thanks CD for helping his successful candidacy for F.R.S.
He is working up Arctic insects. Bombus is found at 83° N., as far north as has been reached.
