My dear Sharpe[,]

Do not trouble about the ^lost letter, as you have answered me half. The other point is to know whether you have, in the course of your Catalogue work, made any detailed measurements of numerous specimens of a species, showing then variability, in the way Mr J. A. Allen¹ has done in his "Winter Birds of Florida."² If you [2] have done so can you lend me any tables of a few such sets of measurements or refer me to where they are published.

Will you also ask your colleagues in the Reptile department whether any such measurements exist showing the individual variability of Lizards & Snakes ^{or in any other animals} when numerous specimens are compared. I want them for a book I am preparing on the Darwinian Theory. I will write to Keulemans³ about the slides.

Yours faithfully | Alfred R. Wallace [signature]
