Letter to James Cossar Ewart from Theodore Dru Alison Cockerell, 25 April 1902

Cockerell writes regarding the notes that he had sent about Equus scotti, and the apparent differences between this species and Equus caballus, an opinion he has now had to alter in the light of information supplied by James Gidley. Cockerell doubts whether the bones of any species of horse would indicate from which hemisphere it originated.
