Letter to James Cossar Ewart from Professor J.U Duerst, 20 July 1908

Duerst writes that he would like to read all of Ewart's works as they are both researching similar subjects concerning the horse. He describes his work on the subspecies Equus caballus nehringi and Equus caballus Pumpellii and states that he is sending Ewart all of his own papers and requests that Ewart do the same.
