# To Alexander Agassiz   10 September [1871 or 1873]1

Down | Beckenham. Kent

Sep. 10.

My dear Mr Agassiz.

I have received a short time ago the several very valuable works mentioned in your circular and which have been so magnificently sent me by your Father and the Museum of Comp: Zoology— At the bottom of the Circular, works in Exchange are asked for—2 Would my Journal of Researches—Origin of Species, Variation of Animals & Plants under Domestication, & Descent of Man, be of any use? If so I would send them; but the American Editions are so very much cheaper, that it would save me a good deal of money if you would instruct your Clerk to tell me what the cost of the whole is in America,3 I could easily procure & send dollars by-which they could be purchased, and this would cause very little trouble.— But I fear that these books would be of very little use—

Pray believe me, yours sincerely & obliged. | Ch. Darwin.

## Footnotes

The possible years are established by the references to Descent, which was published in February 1871, and to Louis Agassiz, who died in December 1873. Louis Agassiz was on an expedition to South America and the Galápagos from December 1871 to October 1872 (Marcou 1896, 2: 183–91).
The circular and the works mentioned in it have not been identified. CD refers to Louis Agassiz. The circulars published by Alexander Agassiz on behalf of the Museum of Comparative Zoology at Harvard University were often requests for specimens, facts, or books, and American publications were offered in return (Dana Fisher, Museum of Comparative Zoology, Harvard University, personal communication).
