    Class: AVES. Birds. GrALLIN/E, Lirw. The Gallinaceous Order. GrALLTJS BAKCXXYA, var. BOMESTICUS, Temmimh. The Domestic Cock and Hen. Zoological Character.—Bill of medium size, strong, naked at the base ; upper mandible arched, convex, bent towards the point. Head surmounted by a dentated comb. Ears naked. Throat wattled. Comb and ivattles of the female less than those of the male. Toes, 3 anterior, united to the first joint; 1 posterior, raised from the ground. Tarsus with a long curved spur.

Habitat.—Domesticated in all parts of the globe. Galli Banckivse Domesficse Ovum. The Egg of the Hen. General Characters.—The eggs of the hen are too well known io need much description. Their specific gravity varies from 1*080 to 1*090. The relative weights of the different parts of the egg are, according to Dr. Prout, as follows:—shell and membrane 106-9 ; liquid albumen 604*2 ; yolk 288*9 = 1000. The liquid white [albumen) and yulk are both official. [§ Albumen Ovi. Egg Album-en. The liquid white of the egg of Gallus Banckiva, var. domestieus, Temrn/mck.] Composition.—Glaire or white of egg consists, according to Gmelin, of albumen 12*0, mucus 2*7, salts 0*3, and water 85*0. According to Dr. Bostock, white of egg consists of water 80*0, albumen 15*o, uncoagulable -matter 4*5 = 100. The coagulability of albumen by heat, and its incoagulability by acetic acid, distinguish it from casein e. Albumen is coagulated by corrosive sublimate. Albumen or glaire is distinguished from albumen of the serum of the blood by its being coagulated by ether. Physiological Effects and Uses.—Highly nutritive, demulcent, and emollient. White of egg is a valuable agent in the treatment of poisoning by coirosive sublimate, sulphate of copper, and bichloride of tin. Its efficacy in these cases depends on the combination of the albumen with the oxide or chloride of the metal. It is used as a demulcent or sheathing agent in all cases of corrosive or acrid poisoning. The white or glaire is also employed as a clarifying agent for wines and some other liquids. Its efficacy depends on its
