Thomas Paton, has the distinction of appearing on the oldest known photograph of a veterinarian in South Africa, namely a group picture of officers and NCO's of the Cape Mounted Riflemen, taken between 1861 and 1870. He obtained his diploma from the Highland Agricultural Society in Edinburgh in 1855 and after service in the Crimean War (1853-1856) was sent to the Cape of Good Hope in 1861, where he remained until 1870. In 1863 the Fort Beaufort Advocate published a letter by him on "The Horsesickness of the Cape of Good Hope", and on 25 May 1867 the Kaffrarian Watchman a letter on "Horse breeding at the Cape and remounts for India". Both letters were reprinted in the British journal The Veterinarian. Several years after he had left the Cape, he published two articles in the Veterinary Journal: "Disease of the maxillary sinuses" (1875) and an observation on "The hereditary transmission of Glanders" (1876). The latter note described glanders in a week old foal. Paton died at sea that same year on his return home from military duty in India.
