Irving writes that he has compared a horse skull at the Geological Museum with that of the Stortford skeleton and concludes that the former resembles the two skulls of Ewart's from Newstead. The skull was found in a brick yard in Melton Mowbray. Irving provides a table of comparative measurements for the Stortford and Melton Mowbray horse skulls.

Osborn states that the pony has arrived safely in New York. He will have the animal photographed for Ewart soon. He mentions not having read the papers by Mendel and Bateson. He announces that he will be writing to the Duke of Bedford to say that he would be interested in receiving the skeleton of one of his Russian horses if one should die. He also states that James Gidley is revising the species of their miocene, and he criticises Othniel Charles Marsh's phylogeny.

Scope and Contents Osborn reports the safe arrival of the Equus caballus and Equus caballus celticus. He feels strongly that the Museum should have Ewart's original type specimen of Equus caballus celticus because it agrees more closely with his original characterisation of the species in the small size of the head. He asks whether it would be practical to have the skin removed and the skeleton sent to them, as the specimen Ewart...

Osborn writes that he will shortly send Ewart a revision of the Equidae, which he calls 'a dry, exhausting piece of work, which is, however, absolutely essential for the more interesting monograph which I trust will follow one day.' He reports that the Celtic pony is now in full coat and is not typical. As it lacks many of the specific characters on which Ewart established the subspecies, he requests again the skeleton and skin of the type.

Osborn writes that he is still working on developing the horse collection at the Museum and preparing his memoir on the Evolution of the Horse. He hears from Director Hornaday that the Scandinavian and Celtic ponies will have to be disposed of as they are eating too much. He once again requests the skeleton and skin of the original Celtic pony to be sent to him.
