SIR C. LYELL TO A.R. WALLACE

_73 Harley Street. July 3, 1867._

My dear Mr. Wallace,--I was very glad, though I take in the _Westminster Review_, to have a duplicate of your most entertaining and instructive essay on Mimicry of Colours, etc., which I have been reading with great delight, and I may say that both copies are in full use here. I think it is admirably written and most persuasive.--Believe me ever most truly yours,

CHA. LYELL.
