Mackenzie provides background details of a particular filly.

Alexander writes that the Przewalski's mare has foaled, although he would have preferred a colt to a filly. He supposes the other foal will turn out to be a light bay without black legs.

Alexander asks whether Ewart wishes to purchase a Mysore bull from him. He is lame but well-behaved, and Alexander would take £10 to save him from going to the butcher. He reports that his filly was hard to handle but is settling down, while her dam should foal soon although she has not wintered well and looks in poor condition. He complains that his pair of Pallas's cats are not healthy.

Alexander writes concerning what money he would take for the sale of the filly, and invites Ewart to come and see his lambs. He adds that he has got a perfectly marked white calf from a pure fawn Jersey by the white bull.

Blunt reassures Ewart that he has not lost interest in his experiments and discoveries. He believes that the four varieties of horse distinguished by differences in their callosites is very important. He is pleased the grey arab given as a filly, has proved useful to Ewart and states that he will be unable to supply a friend of Ewart's with a bay Arabian mare due to the great demand for Arabian horses in the colonies.

Blunt replies to Ewart's acceptance of the gift of a filly. He encloses details of the filly's breeding. He also enquires in what published work he could find details of the fossil of the horse as originally traced by Huxley and Marsh, as he is hoping to begin a genealogy of the Arabian horse.

Mungall writes regarding the filly foal born in 1908 to the yellow dun Shetland mare 'Helen II' and says that due to the distance he cannot say whether the foal has chestnuts (callosities) or ergots. However, the second foal born to the mare does have chestnuts.
