Elwes provides some details of the 'dun-faced sheep' and suggests that Ewart impress on Claud Alexander the importance of photographing the results of his cross-breeding experiments, rather than breeding indiscriminately. He mentions the research of Professor Keller on the Bündner sheep of Switzerland and R.F Scharff in Ireland. He hopes to visit Ewart before going to Shetland.

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.
