Letter to James Cossar Ewart from A.J Pressland, 27 January 1899
Pressland offers information on heredity, following a paper Ewart gave at the Royal Society in London. He cites several instances of cattle with exceptional colouring.
Letter to James Cossar Ewart from James Hay Caird, 25 January 1899
Caird states how interested he had been to read Ewart's article in The Scotsman about experimental contributions to the theory of heredity. He provides example of cross-breeding from his own horses, cows and rabbits.
Letter to James Cossar Ewart from James Wilson, 28 November 1910
Wilson writes that he can give no opinion on the descent of the hornless cattle from the Etruscan, but he suspects they can be traced backwards along the North of Europe. He wonders whether they were the same as cattle from Egypt, and if so, how the geographical divide happened.
