Ewart writes that he is sending Douglas another paper on the development of the horse, but that he will require financial help to continue with the work. He supposes that the Development Commissioners are not worth approaching, but asks Douglas to consider the matter favourably.

The writer, a former student of Ewart's, asks whether Ewart has published a book about his research into the development of the horse.

Author's signature is unclear.

Mettam thanks Ewart for the reprint of his work on the three weeks foetus, and looks forward to further work on the development of the horse. He wonders whether Professor Robinson will give him a copy of his publication on the model constructed from the sections of the foetus.

Hurst requests a copy of Ewart's paper on the Development of the Horse. He has been 'soldiering' since August 1914 and has not had time to keep up with developments in experimental work.

Leach thanks Ewart for the book on the development of the horse. He wonders why mares even after foaling do not get stinted so easily in cold weather as in mild, and why maiden mares do not come into season or get in foal until the end of March or early April and postulates that the cold retards development.

MacBride thanks Ewart for his paper on the development of the horse, and hopes to read the other parts when they come out. He has been asked by Nature to write the obituary for Arthur Darbishire, and asks Ewart for details concerning his regiment and the circumstances of his death.

Letter is unsigned.

Dry asks Ewart for references for his studies on the pre-natal development of sheep, as a graduate student at the Massey Agricultural College, a Miss N. Galpin, is studying the pre-natal development of the coat of the Romney lamb.

Parry writes on behalf of Arthur James Balfour regarding a sum of £500 that is being made available to him to help with his scientific work on the development of the horse.

Catchpole enquires whether copies of Ewart's pamphlet 'A critical period in the development of the horse' are still available, as he is working on problems surrounding the appearance during early pregnancy of sex hormones in the blood stream of the mare.

Robertson comments on Ewart's paper on the development of the horse, particularly on the 'three-toed phase' in early embryonic life. He wonders whether there is any appreciable difference between the embryo of an Arab or thoroughbred mare and a Shire. He imagines that the three-toed stage would persist for two or three days or longer in the case of heavy, coarse breeds.
