Suggests sending his book [Descent?] to Popular Science Review.

Admires CD’s ability to work so hard under adverse circumstances; finds his health makes all work an effort.

First edition [issue] of Descent is exhausted. Asks CD to send corrections at once for a new printing of at least 1000 copies.

Thinks JT’s discovery of a glycerine respirator is an interesting practical discovery. CD has been wondering about the hairs in our nostrils, but doubts that JT has explained their function, since there are hardly enough.

Will ask W. Ogle to observe hairs in nostrils of different races.

Says Descent is "selling like Mad.––" Murray will print another 1500 or 2000 copies. Has received £630 for the 2500.

On Monday he visited Mivart, who is a charming man.

He seemed to be taken aback by CD’s points about the larynx and giraffe.

[See 7507 and 7519.]

He seemed to have forgotten CD’s argument regarding the formation of the greyhound.

Discussed the larynx and the silence of the Cetaceans.

If FD mentions any of this to [Marlborough Robert] Pryor, ask him not to mention it to anyone else "as it is perhaps rather a breach of confidence to repeat even to friends private conversation."

Thanks CD for Variation.

From his work on insect embryology he sees a great parallelism between insect and vertebrate embryology.

The zoological station is slowly advancing.
