Photograph of a horse's cloven hoof.

Osborn thanks Ewart for his visit to Penicuik and asks him for some glass slides and photographs. He recommends that when Ewart visits the British Museum again he studies the hoofs of Onohippidium as they resemble a zebra more than an ass or horse. He asks Ewart to procure him a hoof of an ass or Przewalski's horse if he is able.

Hayes writes that he encloses five photographs of the feet of zebra (photographs not present), and that he wishes to have blocks made to scale. He offers Ewart cliches of the blocks. He asks if Ewart has a foot of a Przewalski's horse, as he would like to photograph it.

Lankester writes that he will be glad to have Ewart's horse paper in reprint and to publish some work on the hoof.

The year is not written on the letter.
