Henrietta’s illness.

CD’s resort to [E. W. Lane’s] water-cure.

Other family news.

Etty [Henrietta Darwin] much improved.

Reference to his "hobby of striped asses".

Sceptical of JBI’s "curious stories" on spirit-tapping: "believe nothing one hears & only half of what one sees".

Going to sea-side for Etty’s health.

Asks JBI further questions about a striped donkey he had reported to CD.

Etty has had a relapse. "What the end will be, we know not."

Thanks for interesting letter which confirms belief that a good observer is a good theorist.

He is glad to hear that HWB, with his wide knowledge of natural history, has anticipated CD in many respects and agrees with the Origin.

Has been thoroughly attacked, especially by entomologists – J. O. Westwood, T. V. Wollaston, and Andrew Murray.

Glad HWB is writing on "equatorial refrigeration"; CD expresses his belief in north to south migration during glacial period.

News of Etty’s health and of neighbours.

Pleased that JBI likes Origin.

CD never expected to convert people in less than 20 years, though now convinced he is "in the main right". Bishop of Oxford’s review made "splendid fun" of him.

Answers HGB’s criticism of Origin.

Explains HGB’s case of differences in rats by adaptation.

CD’s view explains homological and embryological resemblances of each type.

Does not believe all development is at same rate. Cites Australian forms.

Does not see force of objection that origin of life must be explained.

Asks if C. L. Brehm’s subspecies of birds are really characteristic of regions of Germany.
