[77] These instruments were originally adjusted at the temperature of 12¹⁄₂° Cent., or 54¹⁄₂° Fahr. Those now made in France are adjusted at 15° C., or 59° F.; and those made in England, at either 59° or (more usually) 60° Fahr. The standard temperature of the instrument must be known for its correct application.

AREOM′ETRY. Syn. Areome′tria, L.; Aréométrie, Fr. The art or operation of ascertaining the specific gravity of liquids, and hence also their strength or commercial value; hydrometry. See Areometer (above), Hydrometry, Specific Gravity, &c.

ARE′CINA. C₂₃H₂₆N₂O₄. An alkaloid discovered by Pelletier and Comol, in white cinchona bark from Aréca. It is extracted from the bark by the same process as Quinine, viz., by boiling the bark with acidulated water, treating the liquor with lime, and digesting the lime-precipitate in alcohol. The solution filtered at the boiling heat yields a very dark-coloured liquid, which, after a time, deposits the greater part of the aricine in crystals. An additional quantity may be obtained from the mother-liquor by expelling the alcohol by distillation, treating the residue with a slight excess of hydrochloric acid, separating the greater part of the colouring matter by means of a saturated solution of common salts, then throwing down the aricine by ammonia, dissolving the precipitate in alcohol, decolourising with animal charcoal and crystallising.

ARGAMONE MEXICANA (nat. order Papaveraceæ). A tropical American plant, now a common weed growing in almost every part of India. A fixed oil is obtained from the seeds by expression, which has long been employed as an aperient in the West Indies. In half-drachm doses it is said to act as a gentle aperient, and at the same time it allays, apparently by its sedative qualities, the pain in colic. The smallness of the dose, and the mildness of its operation, commend it to the notice of the medical practitioner. Its efficiency is impaired by keeping, the freshly prepared oil proving more active and uniform in its action than that which has been long on
