Draft letter of introduction to Charles Alexander Sheldon from Henry Fairfield Osborn (unsigned), 18 February 1905

Osborn introduces himself and Ewart and describes their research in Mexico on the common breeds of horses which are the offspring or descendants of the horses originally introduced by the Spaniards. He states that they wish to gather as much information as possible about the behaviour and character of the horses, as they can only stay ten days in Chihuahua, Mexico.
