Summary

Forwards H. T. Stainton letter for reply.

Finds many Cucurbita have tendrils with sticking ends.

The "potentiality of so many organs in plants to play so many parts is one of the most wonderful of your discoveries . . . one day it will itself play a prodigious part in the interpretation of both morphological and physiological facts".

Is disgusted with Sabine’s address [see 4708] because of its mutilation of what JDH wrote.

THH’s slashing leader in Reader ["Science and ""Church policy"" ", 4 (1864): 821] – as usual he destroys all in his path.

Edouard Suess attributes to Oswald Heer and HF the generalisation "That the time during which a new species is formed, is (as a rule) very short in comparison with the time during which it persistently presents the same peculiar specific characters". [Edouard Suess, "Über die Verschiedenheit und die Aufeinanderfolge der tertiären Landfaunen in der Niederung von Wien", Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften in Wien (Math-naturw.

Summary

AG’s review of Alphonse de Candolle’s paper [Am. J. Sci. 2d ser. 35 (1863): 430–44] is excellent.

Does not AG consider that orchids oppose Oswald Heer’s view that species arise suddenly by monstrosities?

Reports Gaston de Saporta’s belief that natural selection will ultimately triumph in France.

Is working slowly at Variation.

Summary

Analysing results of last spring’s Primula experiments, CD infers pollen of short-styled plants "suits" long-styled plants.

Summary

Have received Movement in plants. It will interest not only botanists but zoologists and biologists.
