Naski discusses the patterns and colouring of foals hide in comparison with that of their parents and with respect to different breeds and the progeny of hybridisation experiments. He concludes that in most cases, stripes on the foals shoulders and legs tend to disappear when these horses reach maturity. Stripes are most common with white horses and are conversely very rare with brown ones.

Cecil discusses the West Highland pony 'Mulatto' and her suitability for the zebra hybrid experiments. He asserts that 'Mulatto' was never served before she came to Ewart and mentions that 'all my fellows are immensely excited about the zebra cross, in fact they always speak of her [Mulatto] as 'the zebra's lass''.

Cecil suggests where Ewart might procure whole-coloured Arabian ponies in the Edinburgh area for hybridisation purposes

Shipley says how he hopes Ewart's hybrid experiment will succeed. He goes on to recommend a certain Mr Lefroy for his abilities as a field naturalist.

Mitchell informs Ewart that the Council of the Zoological Society of London have granted Sir Clement Hill's request of a loan of a a zebra mare for a hybridisation experiment in the Orange River Colony. He informs Ewart that the mare is now at his disposal.

Blunt says how much he agrees with Ewart's volume about animal hybridisation. He explains that his latest horse sale was not a great success. He also includes a list of the dams, sires and their produce at his horse farm for the year 1900.
