Asks whether he can start soon on translating Expression.

Thinks CD has gone a little too far on St G. J. Mivart’s objection, which he thinks did very little harm in Germany.

JVC’s history of zoology is finished [Geschichte der Zoologie bis auf Joh. Müller und Charl. Darwin (1872)].

Thanks CD for invitation but declines because of his need for a rest instead of coming to England in July.

Repeats his offer to help CD at any time. "I am always learning by trying to answer your questions."
