The author thanks Ewart for sending him the hair samples of his zebras 'Romulus' and 'Matopo', and explaining that he has been much preoccupied by analysing the shell structure of ostrich eggs in the Masai country. He expounds his theories on what the markings and legstripes of zebras can reveal about which species they are. He analyses the colourings and markings of 'Matopo', 'Romulus' etc, and discusses the ramifications of telegony.

The end of the letter, including the author's signature, is wanting.
