The schemes of Brinton, Friedrich Midler, de Quatrefages, Topinard, Haeckel, Flower, and Kollman, will be found in the sum- maries of "Progress in Anthropology," published in the Smithsonian Reports from 1880 to 1891. The latest classification published is Deniker's, who makes 29 races and sub-races of man in 5 main divisions: (A) ^Yoolly hair, broad nose; (B) Curly, or wavy hair; iC) Wavy brown or black hair, dark eyes; (D) Fair, wavy, or straight hair, light eyes; (E) Straight or wavy hair, dark, black eyes; (F) Straight hair.

A radi- cle, or group of atoms, often found in chemical compounds of carbon, but incapable of inde- pendent existence. See Carbon Compounds. ETH YLAIITNE (from ethyl + -amine, from om-monia + -ine), C^H^NHj. An organic base produced when a mono-halogen substitution product of the hydrocarbon ethane is heated with a solution of ammonia in alcohol. The most con- venient method of preparing ethylamine consists in gently warming propion-amide (C 2 H 5 CONH 3 , the amide of propionic acid) with bromine and an excess of caustic potash, the transformation taking place in two steps according to the follow- ing chemical equations: 1. C,H 5 CONH 2 + Br, + KOH = Propionamide GH.COXHRr + KBr + H 2 Bromo-propionamide 2. CYILCOXHBr + 3KOH = Bromo-propionamide C,H S XH 2 + KBr + K 2 CO s + H»0 Ethylamine Ethylamine is a colorless, inflammable liquid boiling at IS.; . It resembles ordinary am- monia in odor and in other properties; combines willi acids to form crystalline salts; and forms double -alts with the chlorides of gold, platinum, etc. When treated with nitrous acid it is changed to ammonia; and when warmed with chloroform and caustic |Mila-li. it is converted into ethyl- iso-eyan ide (a carbylamine having the formula C II NO), which may be readily recognized by its remelj disagreeable smell. See also Amines. ETH'YLENE (from ethyl + -cue), or Oi.k- fiant Gas, C : Hj. A gaseous com pound of carbon and hydrogen Inning a peculiar sweetish odor. It i- colorless and but sparingly soluble in water.
