New eggs have always a rough fresh-looking shell, but this appearance may be effected by artificial means, and the purchaser be cheated with rotten ones, instead of getting fresh. A new-laid egg will sink in water, bad ones are more or less buoyant; but this is a tedious way of testing eggs. The best way is to form a sort of tube with the left hand, holding with the right hand the egg, close and opposite to this tube, in the light. If the egg is good the meat will look clear, and partly transparent; if bad, it will look dark with black spots in it.

Stale fish have always a loose, limber feel, especially about the vent; their eyes are sunk and dim, the scales loose and flabby, and the whole has a dingy, disagreeable appearance. Lobsters and crabs are to be judged by their weight; if they feel light, they have wasted themselves by long keeping.
