As to a certain Prof. Weismann who was much interested in his correspondents experiments concerning birds not eating gaudy caterpillars.

"I have had a letter from Prof. Weismann, who is much interested in your experiments on birds not eating gaudy caterpillars. He wishes much to know whether you have tried any other experiments ... & whether you know of similar ones performed by other observers. Those by Riley of U. States seemed to me the best."

1421 DARWIN (CHARLES).

LETTER SIGNED.

3 pp., 8vo. Kent, 15th November. Circa 1865. 17s 6d

An interesting letter concerning a life of his grandfather, Josiah Wedgwood, which Eliza Meteyard was preparing.

"...I have in my possession a good many letters to him from Dr. Erasmus Darwin (also my grandfather) and if they would be likely to give any information I shall be glad to send them to Miss Meteyard or to you.

"They are chiefly on semi-scientific subjects, and probably would only be useful as shewing what subjects were occupying Mr. Wedgewood's mind and the dates of them." Etc
