Asks CD to write a letter sponsoring him for the Chair of Comparative Physiology at Paris. There are some who do not think his work on artificial production of monstrosities belongs in physiology.

Glad Dareste is candidate for Paris Chair. No subject more important than modification of structure by direct action of changed conditions, and Dareste has thrown much light on subject. Believes monstrosities cannot be separated from slighter variations.

CD’s letter on his behalf made a great impression, but his candidacy nevertheless failed, largely owing to the hostility of Claude Bernard. CD’s opinion sustains his belief that his work will be a service to science.
