Amygdalin

a crystalline principle existing in the kernel of bitter almonds, the leaves of the prunus laurocerasus, and various other plants, which, by distillation, yield hydrocyanic acid. It is obtained, by extraction with boiling alcohol, from the paste or cake of bitter almonds, which remains after the fixed oil has been separated by pressure. When obtained pure, it has a sweetish, somewhat bitter taste, and is not poisonous, and, when treated with alkaline solvents, ammonia is expelled, and amygdalic acid, C20H20O12, is produced.

Amygdaloid

an igneous crystalline, or, as the case may be, vitreous rock (lava), containing numerous cells, which owe their origin to the segregation and expansion of steam, with which all lavas are more or less charged at the time of their eruption. The cells vary in size from mere pores up to cavities several inches, or even feet, in diameter. The cells are generally flattened or drawn out in the direction of flow of the lava, and are frequently filled with mineral matter (amygdules), subsequently introduced by infiltrating water. This is the origin of many of the agates and so-called "Scotch pebbles" of jewelers.

Amyl

the fifth in the series of alcohol radicals whose general for- CnH2n methyl mula is +1, and of which and ethyl are the first two members. It has an agreeable smell and burning taste. It enters into a large number of chemical compounds, most of which as, for instance, bromide, chloride, iodide, etc. are derived from amylic alcohol, which bears precisely the same relation to amyl that ordinary alcohol bears to ethyl, C2H5.

NITRITE OF (C6H11NO2), a valuable drug which must not be confounded with nitrate of amyl, may be prepared by the action of nitric acid on fusel oil (amylic alcohol). It is a very powerful remedy in all convulsive diseases, and is of especial value in angina pectoris, as well as in asthma. Owing to its volatile nature it is usually kept in small glass or composition globes containing from two to five drops, one of which, when crushed in the handkerchief, and the vapor breathed, will often give immediate relief.

Amyloid

a term used both in chemistry and botany, and generally equivalent to "starchy." Amyloids are substances like starch, dextrine, sugar, gum, etc., which consist of carbon, hydrogen, and oxygen. The animal body, chemically considered, is a mixture of proteids, amyloids or carbohydrates, and fats, plus. water and mineral constituents, and the normal food always contains these constituents. Of the three items, proteids are, however, absolutely essential, amyloids and fats only desirable accessories. A compound radical called amyl is formed by the decomposition of starch in a peculiar fermentation-the amylic fermentation.

Anabasis

a-nab'a-sis, a literary name from the Greek, meaning literally a journey upward. Xenophon's Anabasis is an account of the unfortunate expedition of the younger Cyrus against his brother Artaxerxes, 401 B. C. It is written in a simple style. It is the first Greek prose usually read in preparing for college. Xenophon was one of the commanders of a force of 10,000 Greeks, who started from the coast of Asia Minor in the spring of 401 B. C. and marched as far as Cunaxa near Babylon, where Cyrus was killed and the Asiatic portion of his forces routed. The 10,000, however, held together in the face of a host of half a million Persians. After many hardships they regained their native land. The retreat is one of the most famous in history. In celebrity it ranks with Napoleon's retreat from Moscow. The expedition demonstrated the superiority of Greek discipline, and paved the way for the final conquest of Persia two generations later. See Xenophon

Anaesthetic

in surgery, an agent used to produce unconsciousness during an operation. The anaesthetics used chiefly are chloroform, ether, and nitrous oxide or laughing gas. The use of anaesthetics may be said to date from 1800, when Sir Humphry Davy recommended the employment of nitrous oxide to render patients insensible to the pain of operation. Cocaine injected into the flesh is used to produce local numbness to the pain in a part that is to undergo an operation so slight as not to warrant the use of an anaesthetic. In 1910 Dr. Jonnesco of Bucharest, Roumania, visited the United States and demonstrated the use of stovaine and strychnine as a substitute for cocaine. This eminent surgeon performed serious operations without first producing unconsciousness. See Surgery ; Chloroform ; Ether ; Cocaine
