Delighted to hear that HdeV intends working on the causes of variation.
Thanks for Earthworms.
Thanks for Worms.
Recounts a remarkable incident of development of worms in a barrel of wheat. Sends his account, having pondered CD’s view that plants and animals may have had a common ancestor.
Thanks for F. M. Balfour reference, which will serve purpose of his lecture on evolution of the eye.
Is in Cambridge with his son, resting
and reading F. M. Balfour’s Comparative embryology [1880–1].
Sent FM a copy of Earthworms.
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)].
Thanks for presentation copy of Earthworms.
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.
Reports having found orthopteran egg-cases, affixed to a chalk statuette, that had themselves been coated with chalk, without doubt by the insect that deposited them.
Pleasure in reading Earthworms.
Buying land to build a cottage.
Finishing palms for Genera plantarum after three years’ work.
Will send 2d vol. [of his Pflanzenphysiologie (1881)].
CD has occasionally misinterpreted him in Movement in plants; by "after-working" (Nachwirkung) he means "after-working of preceding movements", not of the irritating cause [light].
Thanks for specimen of Dischidia. Will ask Hooker who might dissect it.
Describes worms blocking their burrows with mulberries.
Informs JBD that his book [Earthworms] profited from JBD’s interesting notice ["On the transfer of subsoil to the surface", Proc. Manchester Lit. & Philos. Soc. 16: 247–8].
Second thousand [of Earthworms] has been exhausted and 3d is being printed. Asks CD to send corrections to the printer.
Thanks for presentation copy of Earthworms.
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].
Urges CD to find God.
