Another cause, figs and fried foods, such as rice781 and boiled wheat; things that give rise to vapours,782 such as leeks, and onions, and garlic; and every fat indigestible food, such as beef, hard-boiled eggs, and inwards of animals, and every water-fowl possessing web-feet783: and things that cause eructations, such as new ale, fruits and watery things; lack of evacuation, repletion of food, especially at supper, and a late drink with food.784 A great cause of this sickness is bad order of meals, that is to eat gross food first, then subtle food, and finally gross food again;785 for the alternation is harmful to them, as also eating to excess.
