Glucose {glu'-kos) [yAvuvg, sweet], C 6 H 12 6 , Grape- 

 sugar, Starch-sugar. A substance obtained from 

 starch by the action of the natural ferment, diastase, 

 and by the catalytic action of mineral acids. It 

 is less soluble, and therefore less sweet, than cane- 

 sugar, but equally nutritious. It is much used as an 

 adulterant of cane-sugar. Its varieties are numerous, 

 dextrose andlevulose being the best known. Dextrose 

 differs from levulose in its behavior to the polarized 

 ray of light, which is turned by the former to the right, 

 and by the latter to the left. Glucose crystallizes in 

 nodular masses, melting at 86° F. See Carbohydrates, 

 Table of. G. Vinegar. See Vinegar. 



Glucosid {glu'-ko-sid) \yAvnbg, sweet]. Any member 

 of a scries of compounds that may be resolved by the 

 presence of an acid into glucose and another principle. 



Glucosin [glu'-ko-sin) [y't.vKvg, sweet]. Any one of a 

 series of ptomaine-bases obtained by the action of 

 ammonia on glucose. One of these, C U H 10 N !! (C = 6), 



corresponds in formula and genera^ properties with a 

 remarkable unnamed base formed during the alcoholic 

 fermentation of sugar or molasses, — Aforin's base, 

 C 7 H 10 N 2 : a colorless, strongly refracting, very mobile 

 oil, with a nauseous, pyridin-like odor. It causes 

 stupor, paralysis, impairment of sensibility, dilatation 

 pi the pupils, slowing of the pulse and depression of 

 the temperature, coma, and death. Similar alkaloidal 

 bases have also been found in petroleum, paraffin-oil, 

 chloroform, benzole, ether, amyl alcohol, and in most 

 solvents in common use. 



Glucosis (glu-ko'-sis). Same as Glycosuria. 



Glucosuria [glu-ko-su' '-re-ah) . See Glycosuria. 



Glue (glu) \_gluere, to draw together]. A decomposi- 

 tion-product of many nitrogenous animal tissues. 

 These lose their organized structure, on heating with 

 water, swell up, and gradually go into solution. 

 The solutions, even when very dilute, gelatinize on 

 cooling, forming a jelly that dries to a horny translu- 

 cent mass. This mass is glue, or gelatin, as the finer 

 grades are termed. It dissolves in hot water and 

 forms a liquid possessing notable cementing-power. 

 Two proximate principles seem to be present as char- 

 acteristic in all preparations of glue : glut in, ob- 

 tained chiefly from the hide and larger bones, and 

 chondrin, from the young bones while yet in the soft 

 state, and the cartilages of the ribs and joints. Of 

 these the former much exceeds the latter in adhesive 

 power. Hide-glue is the variety that shows most 

 strongly the adhesive property. Its color may vary 

 considerably without any impairment of its adhesive 

 power. It is usually of a gray to amber or brown- 

 yellow color, and translucent or partially opaque. It 

 should be clear, dry, and hard, and possess a glassy frac- 

 ture. It should swell up but not dissolve in cold water, 

 but should dissolve in water at 62.5 C. (144. 5° P.). 

 Cologne Glue is manufactured from scrap-hide which, 

 after liming, is carefully bleached in a chlorid-of-lime 

 bath and then thoroughly washed. Russian Glue con- 

 tains some inorganic admixture. It is of a dirty-white 

 color, and contains from four to eight per cent, of white 

 lead, chalk, zinc-white, or barytes. Size-glue and 

 Parchment-glue are both skin-glues prepared with 

 special care. Bone-glue or Botie-gelatin is a clear 

 product free from offensive odor. It is much used for 

 culinary purposes and for medicinal applications, 

 and for fining or clarifying wines, etc. It is largely 

 uSed in the manufacture of gelatin capsules, of 

 court-plaster, and of gelatin emulsions with bromid 

 and chlorid of silver for coating photographic dry 

 plates. Patent Glue is a very pure variety of bone- 

 glue of deep dark-brown color. It is very glossy and 

 swells up very much in water. Isinglass, or Fish-gel' 

 a tin, is the finest and best of animal glues. It is pure 

 white, nearly transparent, dry and horny in texture, 

 and free from smell. It dissolves in water at from 

 35 to 50 C. (95 to 122° F.) without any residue, 

 and in cooling produces an almost colorless jelly. 

 Liquid Glue. By the action of nitric or acetic acid 

 upon a solution of glue its power to gelatinize may be 

 completely dissipated, while its adhesive power is not 

 at all interfered with. 



Gluge's Corpuscles. Compound granular corpusi 

 compound granule-cells. Larger or smaller cells 

 densely crowded with droplets of fat, occurring in 

 tissues that are the seat of fatty degeneration. By 

 transmitted light the globules of fat show as black 

 dots, and the whole corpuscle looks like a mulberry. 

 They are the only pathognomonic evidences of soften- 

 ing of nerve-tissue. 



Glumaceous {glu-ma f -she-us) \gluma, a husk]. In 

 biology, possessing chaff-like bracts or glumes.
