In London in June 1769, William Stark aimed to find the cause of scurvy with a series of dietary experiments on himself. He devised a series of 24 dietary experiments and kept accurate measures of temperature and weather conditions, the weights of all food and water he consumed, and the weight of all daily excretions. He started with a basic diet of bread and water and became 'dull and listless'. When he recovered, he resumed experimenting by adding various foods, one at a time - olive oil, milk, roast goose, and others. After two months, he had symptoms of scurvy. By November 1769 he was living on nothing but honey puddings and Cheshire cheese. He considered testing fresh fruits and vegetables when he died in February 1770.
