Galton suggests that Ewart contact Dr Walter Heape for research into insemination and fertilisation. He suggests how beneficial it would be for the Duke of Portland to keep records (including photographs) of his adult pedigree stock. He enquires when Ewart will next be publishing anything concerning hybrid zebras.

Heape writes that he is looking forward to learning of Ewart's conclusions on the ancestor of the coarse-legged horse, which he guesses to have been a wetland horse, and compliments Ewart on his horse handling ability.

Heape writes that it is very difficult to get money, but that Ewart should apply to wealthy breeders. He expresses his approval of Darbishire as the new Lecturer in Genetics.

Heape writes that he will help Ewart to get funds in any way he can, but remarks on his own unsuccessful track record in seeking money. He states that it is hard to make breeders see the value of research and that Ewart should stress the 'practical' side of his experiments.

Heape thanks Ewart for his paper on the Development of the Horse, which he considers an interesting contribution to embryological work.

Heape offers advice on how to compose a scheme of recording the following data from experiments: details and date of service of mare, date of birth of the foal, in conjunction with the number of times the mare was served. This information might indicate any retardation of ovulation, or any hindrance to the passage of sperm into the uterus.
