Memorandum about £250 investment in Patent Siliceous Stone Company, owned by David Thomas Ansted and Frederick Ransome.

Summary

Requests a quart of distilled water for photography to be sent in a clean bottle via the postman on the following day.

Summary

Writes of WED’s recent excursion to Manchester and his future educational plans.

Summary

Has acquired some runts. Thanks WBT for information. Lists pigeons he is sending.

Summary

George Henslow’s curtness to JDH: "an attack of religion".

Embryonic leaves. Adaptive functions and taxonomic significance of cotyledons.

Asa Gray. Separation of sexes in U. S. trees.

Summary

Does JDH’s Wahlenbergia confirm CD’s law? Variations of one species assume the character of a distinct but allied species or genus.

Seed-salting: old ones float and germinate.

Owen’s "grand paper" [? J. Proc. Linn. Soc. Lond. (Zool.) 2 (1858): 1–37].

Summary

Asks THH’s opinion on embryological views of G. A. Brullé [Ann. & Mag. Nat. Hist. 13 (1844): 484–6] and F. M. Barnéoud [Ann. des Sci. Nat. ser. 3, Bot. 6 (1846): 268–96] and on Milne-Edwards’ classification.

Has been reading John Goodsir ["On the morphological constitution of the skeleton of the vertebrate head", Edinburgh New Philos. J. 2d ser. 5 (1857): 123–78].

Has embryology of bats ever been worked out?

Summary

Encloses signed document.

"Much interested about all domestic animals of all savage nations."

Summary

Thanks THH for his cautionary response on Brullé, but departs from THH in thinking that Barnéoud, if true, would shed light on Milne-Edwards’ proposition that the wider apart classes of animals are the earlier they depart from common embryonic plan.

Summary

Thanks JL for saving him from "a disgraceful blunder". Following their conversation he has divided the New Zealand flora as JL suggested and finds genera with four or more species are more variable than those with three or less. It will take several weeks to go back over all his material.

Summary

Asks to borrow several Floras. Must redo calculations as John Lubbock has shown him an important error.

Summary

Believes species have arisen, like domestic varieties, with much extinction, and that there are no such things as independently created species. Explains why he believes species of the same genus generally have a common or continuous area; they are actual lineal descendants.

Discusses fertilisation in the bud and the insect pollination of papilionaceous flowers. His theory explains why, despite the risk of injury, cross-fertilisation is usual in the animal and vegetable kingdoms, even in hermaphrodites.

Summary

Sends TCE West African dog’s skin.

Summary

CD has saved an enormous amount of labour since he replaced the chain on his deep well with wire rope. He now asks readers whether they have had experience of saving on the weight of the bucket by using some material other than oak.

Summary

Arrangements for delivery of pigeons and poultry to Down.
