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.

Praises Orchids.

He has finished his work on Quercus.

H. Lecoq has worked on hybridism,

and P. Duchartre on orchid polymorphism.

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.

Recommends F. J. Ruprecht on vegetable detritus in the black earth chernozem of Russia.

Thanks for Variation.

Offers notes and reflections on Variation.

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

What a book could be written on the application of natural history to man! Gives examples of inheritance in man.

Corrects himself on Robinia pseud-acacia: its spines are stipules, which explains hereditary fixity.

AdeC’s observations on movement of scalp muscles.

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.

Thanks for Descent.

Reveals that it is his own family that has the movable scalp.

The Franco-Prussian war has held up the publication of the 17th and last volume of the Prodromus.

Thanks for Expression, which has made him wonder whether his shyness in public until the age of 55 resulted from fear of subjecting his face to ridicule.

Criticises F. Galton’s Hereditary genius [1869] for neglecting environmental influence.

Thanks for Insectivorous plants.

Thanks for Cross and self-fertilisation.

Discusses geographical implications of inbreeding. Can the length of time an insular flora has been isolated be estimated by its weakness due to inbreeding?

Introduces his son Casimir, who is visiting England.

Thanks for Forms of flowers.

In his Monographiae phanerogamarum [vol. 1 (1878)] he discusses transitional forms of dioecism in three genera of Smilax.

Criticises CD’s use of the words "purpose" and "end", but acknowledges that in English they can mean both cause and effect.

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.

Speculates that the function of "bloom" is to prevent evaporation.

Raised CD’s question about the geographical distribution of glaucous plants at recent botanical meeting.

Congratulations on CD’s long-overdue election to the French Academy of Sciences.

No summary available.

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".

Outlines his efforts to study the inheritance of characters in his family. F. Galton overemphasises the inheritance of good qualities.

AdeC thinks Monographiae phanerogamarum may be of some use to CD for the most nearly correct names to adopt.
