Balfour states that she is returning Carl Hagenbeck's letter to Ewart. She states she has also written to Lord Stanley in connection with Ewart's hybrids in an attempt to persuade him to purchase them. She also enquires whether, during his experiments, he has noticed if offspring from two different species of horse, with strong markings, hark back to a more ancestral type. She enquires whether the mustang is a descendant of the Spanish horse.

Hagenbeck states that he will send Ewart a pair of black rats as soon as he is able to obtain them from the Zoological Gardens in Frankfurt. He is also sending him some photographs of the results of his male lion and tigress hybridisation experiments (not present).

Hagenbeck writes that he has not yet received a reply from Ewart concerning his two zebroids. He hopes Ewart has not sold them, as Hagenbeck would like to have them to show in Hamburg how useful they are. He states that no more experiments have yet been made with the Tsetse disease in zebras.

Hagenbeck sends Ewart details and photographs (not present) of his cross breeding experiments with a lion and a tiger born at the Hagenpark in Hamburg in 1897. He is also attempting to cross a female leopard with a Bengal tiger.

The latter part of the letter is not present.
