DCP-LETT-4153A

From:
Charles Robert Darwin
To:
Osbert Salvin
Date:
11 [May 1863]
Source of text:
Sybil Rampen (private collection)
Summary:

At the suggestion of J. D. Hooker CD offers his opinion on the value of a proposed collection to be made at the Galápagos. The display would not be attractive or appealing to amateurs in natural history, but the scientific value of good collections of every species would be very great if those of each island are rigorously kept separate.
