Camels, a llama, a markhor and a mountain zebra are among the animals in the prints by W. S. Berridge, which are photographs rather than engraved zoological illustrations. They were published in 1912 in The Standard Cyclopedia of Modern Agriculture and Rural Economy, edited by Sir Robert Patrick Wright and issued by the Gresham Publishing Company. The camels include a Bactrian and a young dromedary, and the horned animals a Hunia ram and a West African buffalo identified with Senegal, reaching well beyond the familiar British livestock of an agricultural reference work. The captions keep the descriptive terms of their day.
