Fruit (BETEL-NUT), astringent and narcotic; husk of fruit (PENANG or PINANG), sialagogue and stomachic; both are used as masticatories; wood and nut yield an inferior or bastard sort of catechu; charcoal of the nut highly esteemed as tooth-powder; also given in tape-worm in doses of 1⁄4 oz. and 1⁄2 oz.; said to be more efficacious in coarse than in fine powder.—Doses for Animals. HORSE, 4 to 6 drachms; CATTLE, 4 to 8 drachms; DOG, 30 grains to 2 drachms.
Areca Globulif′era. [L.] Properties similar to the last.
Areca Olera′cea. [L.; Willd.] Cabbage-palm.
ARENA′CEOUS (ăr-e-). Syn. Arena′ceus, L.; Arénacé, Sablonneux, Fr.; Sandig, Sandartig, Ger. In agriculture, mineralogy, &c., sandy; resembling sand; friable.
ARENA′′RIOUS (-nare′-). Syn. Arena′′rius, L.; Arénaire, Fr. Sandy, arenaceous. In agriculture and botany applied to soils (ARENARIOUS SOILS) in which sand is the prevailing and characteristic ingredient; also to plants that grow in sandy or arid soils.
ARENA′TION. Syn. Saburra′tion; Arena′tio, L.; Arénation, Fr.; Sandbad, Ger. In medicine sandbathing; a practice formerly prevalent, in dropsy, of applying hot sand, either by immersion or otherwise, to the feet, legs, or even the whole body.

AREOM′ETER (ă-re- or ăr-re-; āre-e—Smart). Syn. Areom′etrum, L.; Aréomètre, Fr. Literally, a ‘measure of lightness’ or ‘rarity,’ originally applied to any instrument for determining the specific gravity of alcoholic and ethereal liquids; but since applied, like the word ‘hydrometer,’ to instruments adjusted to the densities of all liquids. In this country the term is principally confined to the aréomètres of Baumé, on account of their general use by Continental chemists. The relations and equivalents of Baumé’s scales, as now adopted in France, are shown in the first two of the following Tables:—
