From Robert Swinhoe   10 February 1870

My dear M^r. Darwin,

I must apologise for troubling you again so soon.¹ You told me some time ago of a gentleman who made a study of the skulls of Cattle, and was doing good work with them. Could you kindly inform me where I could find this gentleman?² I have a series of Skulls of the small Chinese Yellow Cow³ together with a photograph of a fine Bull of the same breed and I should like much to get him to examine them before I put them into the Museum.

Your’s very truly, | Robert Swinhoe.
