Encloses Fritz Müller letter, which may be of interest [see 11463].

Encloses statement of U. S. sales of CD’s work to 29 April 1878 and sends a cheque for balance due to CD.

Has forwarded FM’s letter to Raphael Meldola.

Thanks for information on Mimosa.

Would like to know how Cassia behaves in the rain.

Will use TW’s case of gynodioecious Ranunculus if he prints a new edition of Forms of flowers.

Requesting permission to present a declaration against war to the Foreign secretary.

Glad to see TWH for Sunday dinner.

CD will be glad to see TWH on Friday next, and invites him to stay the night.

Germination of Cactaceae; CD wants seeds. Site of action of growth-stimuli.

RM should take no more trouble over the subject [Otto Zacharias’ photos; see 11510].

Will dispatch plants for Kew tomorrow.

Thanks for his notice of Cross and self-fertilisation.

Thanks AFG for his interesting communication. Has sent it to Nature for publication [see 11497].

Hopes that the enclosure [11497] is worth printing in Nature [see Nature (30 May 1878)]. A wood-cut would add interest.

CD’s letter on wide distribution of freshwater plants and animals introduces a letter to him from Arthur H. Gray [see 11497].

Gynodioecism.

Extract from Athenæum 11 May [1878], p. 606, of R. I. Lynch on germination of the provision tree.

Prof. Wood-Mason has examined Otto Zacharias’ insect photographs and confirmed the genera.

RM is going to work up Fritz Müller’s observations into a paper.

Cannot express opinion on RT’s views on earthquakes. To do good work on that subject a man must be deeply versed in wave motions.

Regrets that the arrangement to visit Down must be for Friday.
