Hayes enquires how he could get a copy of Ewart's paper about 'Callosities and the wartless pony'. He also would like to know whether the breed Equus caballus came directly from North America or through its ancestors pliohippus or protohippus. He mentions a paper that Professor William Ridgeway has sent him on the origin of the thoroughbred horse. He also invites Ewart to visit him for hunting.
