CD’s division of his surplus income; fire engines; Sara Darwin’s relatives; GHD’s paper in Nature.

Thanks CD for Earthworms.

Discusses the problem of accounting for difference between nitrogen in permanent grassland and ordinary arable soil. Finds castings of earthworms rich in nitrogen. Asks CD if his observations enable him to explain the source. If from below top-soil, it would be a considerable manuring.

Sends his paper on the comparative anatomy of the assimilatory tissue systems of plants [Jahrb. Wiss. Bot. 13 (1882): 74–188]. This work has made clear to him how CD’s principles produce rich results when applied to plant anatomy.

Also sends a paper on the difficult problem of the gulf between cryptogamic and phanerogamic plants in the evolutionary development, in order to present another proof of the continuity of the phylogenetic development of the plant kingdom.

Thinks that "women though generally superior to men [in] moral qualities are inferior intellectually". Believes that men and women may have been aboriginally equal in this respect but that to regain equality women would have to "become as regular ""bread-winners"" as are men". Suspects the education of children and "the happiness of our homes" would greatly suffer in that case.
