Down Farnborough Kent
March 29th.
Dear Sir
I hope that you will excuse the liberty I take in troubling you; but I heard lately at the British Museum, from Dr. Baird & Mr A. White1 (who said that I might use their names as an introduction) that you had published a very curious paper in the Witness on the effects of the frost on certain shells;2 & I am anxious to see this. They could not tell me at all the date of the Witness, & I now write to ask whether you will take the trouble to inform me, that I may order the copy.
It may be presumptuous, but I cannot resist, expressing the very great pleasure I owe to you, from the perusal of the two of your works, which I have as yet read.3
With much respect | I remain | Yours very faithfully | Charles Darwin
