Gluteus
or GLUTÆUS, three muscles of the hip, the G. maximus, the G. medius, and the G. minimus. The culated muscle, which makes the buttock first is a very large and coarsely fasciprominent in man; its use is to extend the thigh. The second is smaller; it is partly covered by the muscle already mentioned, and acts when one stands. The third is the smallest; it is covered by the second one, and acts as an abductor of the thigh.

Glutin
or GLUTINE, vegetable gelatine. It is obtained along with mucin by heating gluten in small fragments, with alcohol of 80 per cent., and then with alcohol of 70 per cent.; the alcoholic solutions are united, and the half of the alcohol distilled off. On cooling it deposits a mixture of glutin and mucin. The deposit is dissolved in 50 per cent. alcohol, and filtered through calico while hot, and then agitated till it is cold; most of the mucin is precipitated, the filtered liquid is evaporated in a water bath, and the glutin dissolved in alcohol.

Glutton
in zoology, the popular name for the wolverine, a carnivorous mammal of the family Melidæ (badgers). Its length is from two to three feet. It occurs in high latitudes in Europe, Asia, and North America. Its motions are slow, but it manages to feed on mice, marmots, and other rodents, and, when it can obtain them, on larger quadrupeds, alive or dead. Its fur is of little value.

Glycerals
in chemistry, compounds analogous to acetals, obtained by glycerin with aldehydes for 30 hours at a temperature of 170° to 180°; as acetoglycerale, C5H10O30 It boils at

Glyceramic Acid
in chemistry, CHNO or C₂H₂(OH) NH.CO serin. OH, a monobasic, triatomic, amido-acid, obtained by boiling silk with water and evaporating the filtered solution, adding a quarter of its volume of sulphuric acid and boiling for 24 hours; then it is neutralized with excess of calcium hydrate, the filtrate is evaporated and a little H2SO4 added to neutralize it. Tyrosin and calcium sulphate first separate out on evaporation, then serin, and lastly a little leucin. The serin is dissolved in 40 parts of cold water, filtered, the filtrate neutralized by ammonia, and the calcium salt is then decomposed by carbon dioxide.

Glyceryl Oxide
in chemistry, glyceryl ether (C3H8) 2O3. It is obtained by distilling glycerin with calcium chloride. It is a colorless oily liquid, boiling at 172°. It mixes with water, alcohol, and ether.

Glycine
in botany, the typical genus of the sub-tribe Glycerineæ the species, all but one of which are decumbent if not even twining, have alternate leaves with axillary racemes or fascicles of yellow flowers. Locality, the warmer parts of the Old World. G. soja, the erect species alluded to, is cultivated in the East Indies for its beans. From these the Japanese make a sauce called sooja or soy.

Glycocholic Acid
an acid occurring as a sodium salt in the bile of most animals. It is obtained by covering fresh with a layer bile in a tall glass cylinder of ether, and adding 1 c. c. of strong c. of bile; in a few HCl. to every 50 c. days a crystalline mass is formed, which is filtered, washed with cold water, and crystalled out of boiling water; it forms fine needles, which melt at 100°, and are soluble in alcohol; when boiled with barito water it is decomposed into cholic acid and glycocine, C2H4, NO+ H2O = C2H4O5 + C2H5NO2. GI Glycocholic gly acid forms salts which are called glycocholates, the glycocholates of the alkalies and earth metals are soluble in water and in alcohol. Glycocholate of sodium is presolution cipitated from its alcoholic by ether; acetate of lead gives a precipitate which is soluble in alcohol.

Glycodrupose
in chemistry, the strong concretions in pears, produced by thickening and hardening of the cell walls, consists of this substance, together with a small quantity of mineral matter, which is removed by digesting them with dilute acetic acid.

Glyn
ELINOR, (MRS. CLAYTON), an English novelist. the daughter of Douglas Sutherland, of Toronto, Ontario. In 1892, she married Clayton. Glyn, of Kent, England. Mrs. Clayton first attracted wide attention by the publication of her book, "Three Weeks" (1907), a work which produced a sensation by its suggestive qualities. Among her other works are; "Visits of Elizabeth" (1900); "The Damsel and the Sage" (1903); "Destruction" (1919).

Glyoxalic Acid
also called glyoxylic acid, C₂H₂O₃ or CO:OH a dyad compound, containing an aldehyde and an acid radical. Obtained along with glyoxal by oxidation of ethyl-alcohol with nitric acid; also by heating at 140° one part of dichloracetic acid, CHCI COOH with 10 parts of water for 24 hours. Glyoxalic acid is a thick syrup, which can be crystallized over H2So4. It is very soluble in water, and can be distilled in a current of steam. It is a monobasic acid, forming crystalline salts called glyoxalates. By oxidizing agents it is conacid; by nascent hydroverted into oxalic calic gen it is reduced to glycollic acid. It has also the properties of an aldehyde, reducing ammoniacal solutions of silver mirror; also salts, forming a a metallic min unites with alkaline bisulphites. Glyoxalic acid, when boiled with excess of lime water, yields calcium glycollate and calcium oxalate.

Glyoxylic Acid
CHO COOH or CH (OH)2 COOH, a thick liquid, readily soluble in water, but can be prepared in the crystalline condition by long standing over sulphuric acid, in which case the compound has the second formula given above. It is found in young beets, unripe apples, plums, gooseberries, rhubarb, currants and grapes. GLYPHIPTERYGIDE (glif-ip"te-rij' i-dē), a family of moths, group Tineina. The larva has 16 legs or is apodal. It generally mines in leaves.
