Summary

CD is obliged for the offer, but he is "too much occupied to contribute to any periodicals".

Summary

Thanks TCE for telling him of his crossed pigs. When they are grown, he would like to know whether they resemble each other.

Doubts the half-bred Gallus sonnerati will be productive, though he was assured many years ago that such a fertile half-breed once occurred.

Summary

Thanks W. H. Fitch for drawing for the Primula paper. Death of experimental plants delays publication.

Summary

Has received the shipment of skeletons of fowls. Asks TCE species name of Gungla cock. Mentions other specimens.

Summary

Sends three tables on the known geological distribution of genera and subgenera of Brachiopoda. Has been continually puzzled by intermediate forms, and is convinced that the greater number of species can be linked together. "Natura non facit saltum."

Summary

Regrets the error in the bill and receipt. CD is surprised at so large a reduction in profit in the last edition.

Summary

Asks how many wild Chillingham cattle are killed each year. Interested in rate of increase.

Summary

Information is sought from correspondents regarding the mental powers of Polish and other tufted fowls. CD finds it hard to believe that the protuberance of the front part of the skull, which is accompanied by a change in the shape of the brain, would not produce a change in mental powers. References to Bechstein, Pallas, and Tegetmeier regarding the stupid behaviour of these birds.

Summary

CD is unable to locate his specimens of two Falkland Island birds [Opetiorhynchus].

Summary

Sends some replies to CD’s queries and data on pigeon flights between Bordeaux and Verviers.

Summary

Discusses results of his examination of fowls’ skeletons. Wants to quote TCE on variation in skeletons of allied species. Asks about skulls of birds with topknots.

Summary

Acknowledges receipt of promissory note for £372 from JM for third edition of Origin.

Summary

Discusses family and domestic matters.

Summary

Thanks for information about natural increase of Chillingham cattle. Compares with case in Paraguay.

Summary

Asks D. Beaton whether varieties of the same species of Compositae frequently cross by insect agency or other means. Do the raisers of hollyhocks have to keep each variety separate for raising seed?

Summary

Asks TCE to confirm some general statements on resemblances in skeletons of birds of same genus.

Summary

Henslow’s long suffering.

Donald Beaton’s articles in Cottage Gardener clever but not to be trusted.

Summary

[Letter printed in REG, Tabular view of the primary divisions of the animal kingdom.] Dedicates his book to CD in testimony of his admiration of CD’s successful attempt to throw light on "the mystery of mysteries of organic nature".

Summary

Describes results of his experiments with hollyhocks. Some varieties breed true even though growing near others. This suggests that their pollen is "pre-potent" over that of other varieties, which is not the case with most plants. Asks some questions on which he would be glad to have correspondent work.
