The Reader.

Politics and science.

Health improved by Bence Jones’s diet.

[Dated "Thursday 27th" by CD.]

Feels success of theory depends on acceptance and application by good and well-known workers, like JDH, Huxley, and Lyell.

Summary

Criticisms and comments on JDH’s "Insular floras" in Gardeners’ Chronicle [(1867): 6].

Summary

Thanks JDH for response on variation. Studying variations that seem correlated with environment, e.g., north vs south, ascending mountains.

CD’s weed garden: observations on slugs killing seedlings.

Seed-salting. One-seventh of the plants of any country could be transported 924 miles by sea and would germinate.

Summary

"Law" [see 2092] correlating variability and abnormal development not confirmed by JDH for plants.

CD studies struggle for existence in his weed garden.

CD experimenting on pollination mechanism of Leguminosae. Asks JDH to investigate Fumariaceae.

Summary

"Climbing plants" sent off.

Encourages JDH to include notes on gradation of important characters in Genera plantarum or to write a paper on the subject. Has given prominence to gradation of unimportant characters in climbing plants. Believes that it is common for the same part in an individual plant to be in different states. Same may be true of important parts – for example position of ovule may differ.

Two articles in last Natural History Review interested him; "Colonial floras" [n.s. 5 (1865): 46–63]

and "Sexuality of cryptogams" [n.s. 5 (1865): 64–79].

Fact of similarity of orders in tropics is extremely curious. Thinks it may be connected with glacial destruction.
