Thanks for gift of Souvenirs d’un naturaliste (Quatrefages 1854).
Can AdeQ ask M. J. P. Flourens about experiments which show that hybrid offspring of dogs, wolves and jackals are sterile between themselves in the third generation.
CD cannot obtain a copy of Dureau de la Malle’s work on breeds of horse: can AdeQ assist?
Can AdeQ verify the statement that the moths of the several races of the common silkworm are very similar?
When the female moth comes out of the cocoon, are her wings less developed than those of a male moth at the same stage?
Specimens obtained from Charles Martins will be most interesting.
Comments on QdeB’s book [Physiologie comparée (1862)].
Wishes to introduce his son, George Howard Darwin.
Has glanced at the second of AdeQ’s articles on natural history in Revue de deux mondes; ordered first article but second is already out of print.
