Thanks AdeC for great pleasure his new book [Histoire des sciences (1873)] has given him. Comments on several of the essays.

When AdeC backs up Asa Gray in saying all instincts are congenital habits, CD must protest.

Asks several questions about butterflies of the Alps discussed on p. 322 [of Histoire].
