By about 1750 the Dutch, interested in the East Indies trade, and the British, with their expanding navy, had discovered that fresh fruit and fruit juices helped to keep their sailors well. But on long naval voyages scurvy continued to injure large numbers of the forces. The famous Captain John Cook, in his voyage around the world, man- aged to keep his crew in very good condition for over three years through the use of lime-juice. For this achievement he received a medal from the Royal Admiralty in 1776. Within twenty years the use of lime-juice or lemon-juice became obligatory in all the ships of the British navy, with satisfactory results in preventing scurvy.

After a short period of time they lose control of their bodies and at times draw back their necks in typical polyneuritic fits. Such animals can be quickly re- stored to health by feeding them vit
