"The sight and smell of raw meat are especially odious to me, and I have often thought that if I had had to be my own cook, I should inevitably become a vegetarian, probably, indeed, return entirely to my green and salad days."
1897, Robert Hunter and Charles Morris, Universal Dictionary of the English Language, volume 4, page 5045:
Vegetarian Society(..) A society (..) formed at Manchester in 1847, to promote the use of cereals, pulse, and fruit, as articles of diet; and to induce habits of abstinence from fish, flesh, and fowl, as food.
vegetarian... One who abstains from animal food, living exclusively on vegetables, milk, eggs, and the like. The more strict vegetarians eat vegetables and farinaceous food only, abstaining from eggs, butter, milk, and in some cases, honey.
