Sends JDH part of MS for chapter 3 of Natural selection ["Possibility of all organic beings crossing"] to be corrected and returned.
JDH’s report of Podostemon flowering cleistogamously under water in Bengal.
[Copious revision by JDH.]
His observations on Subularia: has never seen it in flower in the air.
Questions JDH on separation of sexes in trees in New Zealand flora.
Cites cases of leguminous plants whose cleistogamic flowers produce more seed than perfect flowers. [See Forms of flowers, p. 326.]

Compliments JB on publication of 'Trigonometry of the Parabola.' Recalls JH's papers on catenaries.
Thanks GB for information on apetalous flowers. "The whole order [Leguminosae] will remain my detestable enemies."
Sends another pamphlet on the gold question. On the last page he will find JM has adopted JH's suggestion, though he does not give the source. Thinks that these suggestions should prove useful to France.

Is glad WBT is willing to describe the poultry CD can acquire. Sir James Brooke promises Borneo fowls.
Has received news of a cargo of cryolite from Greenland. Outlines the various possibilities of using it for the manufacture of chemicals and glass. Sends his method of manufacturing aluminium.
Needs advice concerning Egyptian money. Proposes coining money there as a solution to some of the problems.
CD is collecting all the evidence he can on natural crossing of varieties of plants. Asks readers of Gardeners’ Chronicle to give evidence "showing either that Leguminous crops, when grown close together do sometimes cross or on the other hand that they may invariably be grown close together without any chance of deterioration".

Would be inclined to try a combination of cryolite and silex to obtain a glass. Comments on his process for decomposing alumina by cyanide of sodium. Sorry to see that FK uses the current forms of chemical notation.
He is steadily and very hard at work on "Variation" [Natural selection] and finds the whole subject "deeply interesting but horribly perplexed".
Has done New Zealand flora calculations. Results support CD’s theory of necessity of crossing. Trees tend to have separate sexes.
Agassiz has informed him that the mice and rats of Mammoth Cave are American in type.
Alludes to CD’s doubt of the principle that "progress of life on the globe is parallel with the development in different tribes". Outlines his own ideas on the "unfolding of the type-idea" and its "parallelism with the law of development in the embryo".
