Reports on the snakes he collected in the Galapagos.

Sends his photograph.

Asks for any information of well-marked sexual differences in snakes, batrachians, or lizards. The rattlesnakes at the Zoological Garden differ considerably in colour.

Thanks AG for information.

Asks AG for details of variation in patterning of the banded snake.

Sends some questions on secondary sexual differences of fishes [missing], which he hopes AG will look over.

Invites AG to come to Down.

Encloses queries on sexual differences and nest-building habits of fish.

Thanks for answer to questions.

Has analogous questions on reptiles that he will send to AG. The subject interests him, but CD must try not to fall into his common error of "being too speculative".

Sends a list of queries for AG.

Asks whether AG can supply specimens for illustrations [for Descent]. Hopes Mr Ford will do the drawings.

Is "astonished & deeply grieved" at loss [of AG’s wife].

Thanks AG for full answers to queries.

Delighted Mr Ford will undertake drawings [for Descent]; comments on some illustrations he would like.
