The value of an ox rose from five solidi, (fifteen shillings,) at Christmas to two marks, (four pounds,) and afterwards much higher; a kid or lamb, from one shilling to eighteen of our present money: in the second famine, a loaf of bread, or the head of an animal, sold for a piece of gold. More examples might be produced; but it is the ordinary, not the extraordinary, prices, that deserve the notice of the philosopher.
