a stag, or male-deer, in the fifth year. See Cervus, Mammalia Index.

Hart-Beef, or Quanga. See Capra, Mammalia Index.

Hart's-Horns, the horns of the common male deer.—The scrapings or raspings of the horn of this animal are medicinal, and used in decoctions, tisanes, &c.

Hartshorn jelly is nutritive and strengthening, and is sometimes given in diarrhoeas; but a decoction of burnt hartshorn in water is more frequently used for this purpose, and is called hartshorn drink.

The coal of hartshorn, by being calcined with a long continued and strong fire, is changed into a very white earth, called hartshorn calcined to whiteness: This earth is employed in medicine as an absorbent, and administered in dysenteries and labour pains, which are supposed to be caused by acid and ill-digested matters. This earth levigated is the basis of Sydenham's white decoction, which is commonly prescribed in these diseases.

The salt of hartshorn is a great sudorific, and given in fevers with success; and hartshorn also yields, by distillation, a very penetrative volatile spirit.
