Horse serum laboratory at Elstree, 1915
The laboratory of the horse serum farm at Elstree, 1915. One unusual contribution of the horse to the war effort was as a supply of serum which acted as an antidote to tetanus poisoning, also known as lockjaw. Serum, or blood fluid with the clotting agents removed, is collected from the blood of specially selected horses, who have carefully infected with the disease, and so built up an immunity to it
