Thanks CD for accepting dedication.

Asks CD to support his candidacy for position as Registrar of the University of London by talking to Sir John Lubbock, one of the most influential members of the Senate.

Has lately found frog that has eggs on its back.

Pupae of caddis-flies living on rocks have lost fringe of hairs on their feet. In species that live in the water these are used for swimming.

Respects Leopold Würtenberger’s work. Will initiate inquiry if CD wishes. LW’s work suffers from his limited circumstances. Will assist him if he asks.

Mentions his own forthcoming work ["Zur Kenntniss der Fauna des untersten Lias in den Nordalpen", Abh. K.-K. Geol. Reichsanst. 7 (1874–82), vol. 5].
