Gives his opinion on vivisection. CD detests cruelty but believes that physiology "is one of the most important sciences" and that it cannot progress without experiments on living animals.

Sends M. Guthrie’s book [On Mr Spencer’s formula of evolution (1879)], although HEL may not care to read it having seen Moulton’s letter [12350].
