Thanks to CD’s help Zoological Station has passed a crisis and is now flourishing.

Is writing pamphlet on "the origin of vertebrates and the principle of succession of functions" [see 9991 and 10003]. It is likely CD will not be pleased with it, but he thinks he must now, after seven years, bring it out. Seeks to open the way for a new series of theoretical questions.

Agrees to have his name on the list of naturalists to whom annual report [on zoological station] should be sent.

His health has been very bad for last six weeks.

THH sends to AD a draft, prepared by himself and CD, of a statement for a subscription fund to assist AD’s Naples Zoological Station.
