![thin transparent membrane, situated be- tween the amnion and the chorion. 2. A vehicle or sac projecting at the lower end of the alimentary canal, in the embryo. 1. Allantoic Acid. A compound de- scribed by Vanquelin under the name of amniotic acid, and said to exist in the liquor amnii of the cow. It was found by Dzondi to be present solely in the liquor of the allantois, and to be in fact the urine of the foetus. 2. Allantoin. A crystalline substance found in the allantoic fluid of the cow, and produced artificially by boiling uric acid with the pure-coloured oxide, or peroxide, of lead. [ALLIACEOUS (alium, garlic). Be- longing to, or of the nature, of garlic] ALLIGATION (alligo, to bind). An arithmetical formula for ascertaining the proportion of constituents in a mixture, when they have undergone no change of volume by chemical action. When alco- holic liquors are mixed with water, there is a condensation of bulk, which renders this arithmetical rule inapplicable. The same thing occurs, to a certain extent, in the union of metals by fusion. ALLIUM (oleo, to stink). A genus of plants of the order Asphodelece, containing an acrid principle. 1. Allii Radix-.

It need scarcely be stated that such a defi- nition, so applied, is only an invention of the homoeopathic fraternity, to serve their own purposes. Mayne.] See Homoeopathy. [ALLOTROPIC (flXA0f, other; r9onn, change). That modification of elementary bodies, by which, when to a well marked organic compound type, a certain quantity of carbon and hydrogen is added, every such addition produces a new compound, analogous in proportion to the first.] [Allotropiam. The capability of certain elemeuts of existing in two or more condi- I tions, in which they possess different physical and chemical properties.] ALLOXAN. The erythric acid of Brug- natelli, discovered in the decomposition of uric acid. Alloxunic acid is produced by the meta- morphosis of alloxan by caustic alkalies. Alloxantin. A crystalline substance observed by Dr. Prout among the pro- ducts of the decomposition of uric acid by nitric acid. ALLOY. A term applied to a combi- nation of metals by fusion, except when mercury is one of them, in which case, the compound is called an amalgam. ALLSPICE. Pimento berries, or Ja- maica pepper; the fruit of the Eugenia Pimevta, a Myrtaceous plant. ALLU'VIUM (alluo, to wash near to).

A. serrulata. Common American Alder. This species has analogous proper- ties to the preceding.] ALOE. A genus of plants of the order Asphodelece; characterised by an intensely bitter taste. 1. Aloes SpicatcB Extraction. L. Aloes; an extract prepared from the Aloe Spi- cata, or Socotrine Aloe. In this species the bitter taste is accompanied by an aro- matic flavour. 2. Aloe Hepatica; Extraction. E. D. Barbadoes Aloes ; an extract prepared from the Aloe Hepatica, formerly Bnrbadensis: of a much stronger and less pleasant odour than the preceding. 3. Fetid or- Caballine Aloes. A very impure variety, having the appearance of bitumen, and used chiefly for horse medi- cine, as one of its names imports. 4. lied Aloes. A variety supposed to be a natural exudation from the Aloe Spi- cata, which has concreted in the sun. 5. Mocha Aloes. Probably only a variety](https://iiif.wellcomecollection.org/image/b2103753x_0039.jp2/full/800%2C/0/default.jpg)
