From Alphonse de Candolle 14 August 1877
Summary
Thanks for Francis Darwin’s Dipsacus paper.
Dislikes the word "protoplasm", because improved microscopes will uncover more fundamental substances. Also "plasma" merely hides the ignorance of modern chemists.
Expects waxy, glaucous-leaved plants to be most frequent in dry temperate climates.

Finds CD was correct in Variation: hybrid bees tend to sting more often than pure-bred bees.
Preparing a second edition of the chapter on the origin of cultivated plants in his Géographie botanique. The work done since 1855 confirms his opinions.

Thanks for Movement in plants. Praises the terms CD introduces, but criticises CD’s use of the teleological word "purpose".

From Alphonse de Candolle 13 June 1862
Summary
Has read the Origin several times. His position is like Asa Gray’s: he wishes to believe in descent, but proofs of natural selection are lacking.
Looks forward to CD’s promised large book.
Thanks for Primula paper [Collected papers 2: 45–63]. Did CD sow the seeds of his crosses? One would like to know whether the two forms reappear at random.

From Alphonse de Candolle 3 June 1866
Summary
In London for the Botanical Congress; regrets missing CD.
Lyell and CD have mistaken H. Lecoq’s position on glaciers. He has not denied the possibility of a glacial period, only that decreased temperature is needed for their extension.

Summary
Offers notes and reflections on Variation.
Not convinced by Pangenesis, particularly its dependence on the Cytisus [graft hybrid] examples [ch. 27 and ch. 11].

From Alphonse de Candolle 28 September 1869
Summary
Reports on the differences of growth and development of plants of three species grown at Geneva from seed collected at different localities. Forwards seed for CD to plant and observe differences in development.
Carl Linsseer has published a memoir on the times of flowering, foliation, etc. of diverse species in different parts of Europe [Mem. Acad. Imp. Sci. St.-Pétersbourg 7th ser. 11 no. 7 (1868)] and concludes that the northern forms are more forward and that this is hereditary. AdeC’s experiments carried out on annuals, show only the effects of heredity; probably the direct action of physical conditions affects development, at least in perennial species.
