Discusses arthropod structure and the nature of the corium.

JL is studying Cynipidae. CD sends galls for his examination.

Thanks JL for saving him from "a disgraceful blunder". Following their conversation he has divided the New Zealand flora as JL suggested and finds genera with four or more species are more variable than those with three or less. It will take several weeks to go back over all his material.

Huxley and William Sharpey praise JL’s paper [? on Daphnia, Philos. Trans. R. Soc. Lond. 147 (1857): 79–100] at Philosophical Club.

CD sees JL’s cases of same organs varying greatly in allied forms as a serious difficulty in regard to his own ideas.

Development of aphids; apparent absence of vermiform stage.
