Letter to James Cossar Ewart from Carl Hagenbeck, 09 November 1903
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.
