Cecil outlines details of a dun-coloured mare that he has just purchased, with a chestnut stripe down its back. He also mentions some hybrids that he is hoping to transport to India.

Cecil thanks Ewart for 'the photo of Mulatto and Romulus' (Ewart's first zebra/horse hybrid and dam) and mentions that the Scottish Farmer should be sending 'Reid of Wishaw' (Charles Reid, the photographer). Cecil suggests that Reid should photograph Ewart's various animals (zebra, mule, donkey as well as Mulatto and Romulus) to highlight the differences in stripes between father and son, and the absence of stripes in the non-hybrid animals.

Cecil explains the breeding and ancestral history of the West Highland pony 'Mulatto', describing the possible reasons for her colouring and markings. He also refers to documents and sketches enclosed for Ewart (not present).
