Letter to James Cossar Ewart from Richard Francis Scharff, 02 December 1910

Scharff writes that a great deal has been written about the domestication and place of origin of Bos taurus primigenius, but that Professor Keller has shown conclusively that its domestication took place in Greece around 1500BC and that it never existed in Northern Asia or North America. Scharff remarks that the Bison bonasus is undoubtedly a near relation to the American bison.
