Accepts PLS’s offer to read proofs of [Descent].

W. H. Hudson’s paper is interesting.

Sends two sheets [of Descent] for correction of names of birds. PLS will save him many disgraceful misspellings. Descent now being prepared in five foreign editions.

Is sending by this post three sheets and will send another tomorrow thus almost completing the part on birds. His congratulations and thanks for PLS’s labours with them.

Sending two sheets [of Descent]. About one-and-a-half more will complete PLS’s task.

CD is obliged for PLS’s correction [of Descent proofs]. Will add a caption to the woodcut [of the wart-hog] since it is too late to make a new one.

Is infinitely obliged for a correction. "You men who do only or chiefly original work have an immense advantage over compilers like myself, as you can know what to trust." Wishes he had consulted PLS before using A. E. Brehm’s Thierleben woodcuts [for Descent]. PLS’s assistance has saved him from "endless blunders"; he now feels safe.

Will send F. Du Cane Godman’s book [Natural history of the Azores (1870)] as soon as he returns home.

Encloses a memorandum [missing] drawn up by W. H. Flower, Huxley, and himself, defending Charles Wyville Thomson against an attack made upon him.

Lists land birds of Galapagos and discusses their distribution on mainland of S. America.

Informs CD that Sylvicola aureola may be a distinct species but is a close ally of S. aestiva of N. and S. America and perhaps only a "climatic variety".

Corrects CD’s statement [Origin, 3d ed.] that Madeira does not possess one peculiar bird. There is one, out of the 99.

Circular requesting recipients to sign an enclosed [missing] statement [relating to appeal for Naples Zoological Station] if they approve of it.
