Will GHD ask Lord R[ayleigh] whether "gas-men in testing light, exclude the diffused light".

Is obliged to GHD for arranging everything.

Sorry about the proof-sheets.

Thanks JW for book [Das Bewegungsvermögen der Pflanzen (1881)]. Discusses movement in plants.

Glad book [Earthworms] will soon be published.

G. J. Romanes has copy and often writes reviews for Nature. Probably did not know it was incorrect to publish it prematurely.

Does not believe imagination of mother can affect new-born infant.

Thanks TLB for the collection of his writings.

Says that salt water kills earthworms.

Interested in ERL’s study of worm anatomy.

Has been reading Julius von Wiesner’s book [Das Bewegungsvermögen der Pflanzen (1881)]. Comments that it is "an excellent book, but he vivisects me in the most grievous terms, but most effectively".

Has been experimenting on aggregation of chlorophyll but with little success.

Visiting his son Horace.

Studying action of carbonate of ammonia. Finds similar looking Euphorbia root cells react differently.

Intrigued by Dischidia rafflesiana, whose pitchers manufacture manure-water that nourishes adventitious roots. Does JDH know histologist for detailed study?

Julius von Wiesner’s criticism of Movement in plants "vivisects" CD in "a most courteous but awful manner" [Das Bewegungsvermögen der Pflanzen (1881)].

Thinks FD should review Julius von Wiesner’s book [Das Bewegungsvermögen der Pflanzen (1881)]. CD comforted that Wiesner’s experiments support their findings but finds it laughable how differently he has interpreted them.

Thanks for specimen of Dischidia. Will ask Hooker who might dissect it.

Further comments on JW’s Das Bewegungsvermögen der Pflanzen [1881]. Discusses heliotropism and sensitivity of root tips. Bewildered by their differences concerning circumnutation.

Has no corrections. Pleased at sale of book [Earthworms].

Thanks for errata [in Earthworms].

Thanks WP for copy of his Die Seele des Kindes [1882].

Earthworms is selling well.

Discussed how to repeat some of their plant experiments while in Cambridge.

Comments on Julius Wiesner’s views on plant movement.

S. H. Vines was very much surprised at the action of carbonate of ammonia on the roots of Euphorbia.

Profuse thanks for plants.

Specifies which euphorbs he wants. Euphorbs’ alternate rows of ammonium carbonate reactive/non-reactive cells are worth more study.
