A red-brown fluid of musky odour, obtained by the action of weak chlorine water on aloisol. It boils and is decom- posed at 250° C. (482° F.) Insoluble in water, soluble in alcohol and ether; it becomes resinous on exposure to the air. Al'oes-WOOd. (F. bois d'aloes, calam- bac; Gr. Aloeholz.) Considerable doubt has existed as to the tree from which this sub- stance is obtained. It would appear that the true aloes-wood is a product of the Aloexylum agallochum. It is of ashy brown colour, veined, soft when recent, becoming hard when kept; of agreeable odour, and bitter, aromatic taste and gives a pleasant perfume when burnt. It is supposed to consist largely of resinous concre- tion. It is used as an analeptic and as a stimulant perfume, when burnt, in vertigo and paralysis. It is also called Agila wood. An aloes-wood is obtained from a species of Aquilaria ; also a cordial, and used in gout and rheumatism. A., false.

According to some, an orange powder obtained by the action of nitric acid on aloes with heat, and distinct from chrysammic acid. Aloet'ica. Aloetic remedies; medicines containing aloes. Al'oetine. The purified juice of aloes. It crystallises in prismatic needles of a beautiful sulphur-yellow colour. Its taste, at first imper- ceptible on account of its insolubility in water, soon becomes intensely and persistently bitter. It is probably an impure substance containing Aloin. Aloex'ylon. A synonym of Aloes-wood. Aloex'ylum. ('A\drj, aloe; ^xiKov, wood.) A doubtful Genus of the Suborder Ccesalpinice, Nat. Ord. Leguminosce. Sepals four, caducous, one larger than the others, and falciform; petals five, unequal; stamens ten; ovary compressed; fruit woody, smooth, falciform, monospermous ; seed arillate. A. ag^al'locbum. Hab. Cochin China. Yields Aloes-wood. A lofty tree, with alternate, simple, lanceolate, petiolated leaves, and terminal many-flowered peduncles. A. ova'ta. Also yields Aloes-wood.

Aloin is a glucoside, and is obtained by crystal- lization from a concentrated aqueous solution of aloes and recrystalli^ation. It consists of minute
