It is not in Egypt only that the perdicium2243 is eaten; it owes its name to the partridge,2244 which bird is extremely fond of digging it up. The roots of it are thick and very numerous: and so, too, with the ornithogale,2245 which has a tender white stalk, and a root half a foot in thickness, bulbous, soft, and provided with three or four other offsets attached to it. It is generally used boiled in pottage.2246
