Lobsters.
IF a lobster is fresh, the tail will be stiff, and pull up with a spring; but if it is stale, the tail will be flabby, and have no spring in it. This rule, however, concerns lobsters that are boiled; but it is much better to buy them alive, and boil them yourself, taking care that they are not spent by too long keeping. If they have not been long taken, the claws will have a quick and strong motion upon squeezing the eyes, and the heaviest are esteemed the best. The cock-lobster is known by the narrow back part of his tail. The two uppermost fins within his tail, are stiff and hard; but those of the hen are soft, and the tail broader. The male, though generally smaller than the female, has the higher flavour, the flesh is firmer, and the body of a redder colour, when boiled.
