one to tliree days tlie pieces of wood will be fo perfcclly ce- 

 niCHtcd, that boards, thus cclicring, will as ri.-?.dily break in 

 any part as feparate at th? jiiiittioi;. Glued boards will not 

 fet in a freezing tempcratnre; the ilifFcning being occalloncd 

 by the evaporation of the fuperflnnus matter of the glue, 

 whicii is prevented by a confidcrable degree of cold.

Glue, Fyh, is a lort of glue made of the nervous and mu- 

 cilaginous jjarls of a large fiili, found chieily in the Ruffian 

 feas. 



Thcfe parts, being boiled, bear a near rcferr.hlance to that 

 vifcid matter found on the ftins of cod-fi(li Wlven boiled 

 to the confiftence of a jolly, thev fjinad it on a leaf of 

 •paper, and tonn itii;to cakes; in which ftatc it is fcnt to us. 

 Filh-glue is of confidorahle ;ife in medicine, and divers 

 others arts; where it is better known under the name of 

 ii'mglais and ichthvocolla. See IsiNtJLAW. 



A flrong ai.d nnc gluo may be prepared with ifinglafs and 

 fpirit of wine thus: fteep the ilinglafs for twenty-four houi's 

 M fpirit of wine or common brandy. When the meiiilruum 

 lias opened and mollified the ifinglafs, they mull be genllv 

 boiled together, and kept ihrring till they appear well 

 mixed, and till a drop th.ereof, fulTcred to cool, prefcntiy 

 turn? to a Itroii;;- jelly. Then Rrain it, while hot, through 

 a clean iinen cloth, into a veiTcl to be kept clofe Hopped. 

 A gentle heat luffics to diiTolve this glue into a tranfparent 

 and almoit colourlels fluid, but very ihxmg; fo that pieces 

 of wood, glued together with it, will feparate elfewhcre 

 than in the parts joined. Boyle's Works abridg. vol. i. 

 p. 130. 



A ftrong compound glue may be niade by infufing a mix- 

 ture of common glue, in fmall pieces, with ifinglafs glue, 

 ■in. as much Ipirit of wine as will cover them, tor about 

 twenty-four hours: then melt the whole together, and add 

 as much powdered chalk as will make it an opaque white. 



A ftrong glue, that will refill moifture, may be obtained 

 by diffolving gum fandarac and maftic, of each two ounces, 

 in a pint of fpirit of wine, and adding about an ounce of 

 clear turpentine: then take equal parts of ilinglafs and 

 parchment glue, and having pounded them into fmall pieces, 

 pour the folui ion of the gums upon them, and melt the mix- 

 ture in a covered veffel, with a heat lefs than that of boiling 

 water: then ilrain the glue through a coarfe linen cloth, 

 and putting it again over the fire, add about an ounce of 

 po\\'dcrcd glafs. 



Or, a llroiig ghie, that will refill water, may be made 

 bv adding lialf a pound of common ifinglals glue to two 

 . quarts of Ikimmcd milk, and evaporating the mixture to a 

 • Cupconfillcnce. 



A glue, that will hold againfl fire and water, may be 

 made by mixing a handful of quick-lime with tour ounces 

 ■of linfeed oil, boihng them to a good thicknefs, and 

 fpreading the mixtiiR^ on tin plates in the (liade : it will thus 

 become exceeding hard, but will eafily be dilTolved over a 

 ^re, and be fit for ufe. See C.t;MKXT. 



GLUMA, a h'lifk, in BoUmy, is the peculi.ir calyx of 



grafl'es and grafs-hke plants, and indeed their corolla, at 



-lead what is fo termed by Linnseus, is of the fame chafly 



■nature. Huflcs or Glumes are ufuallv comprelfed, embracing 



each other at the bafe ; more rarely thev are deprelied, flat- 



'ttned vertical! V, as i Onaking-grafsor Briza. To thehuilc 



belongs the ari/!a or awp, (fee AliLsiW,) which is a briille- 



ihaped appendage, ufnal'y fpiral, and poffeffing the pro- 



-pertics of an hvgi-omotcr. It originates from the midrib or 



kee! of the hul1<, and in either terminal or dorfal, being in 



-he latter cafe placed fometiincs verj' far do^vn the back of 



•!.f huik, i.s ill rriany fpcc es of jiiK'ia., and in thcfe inilanccs 



G L U 



it belong .^ to the glumes that conftitute the cQrolLi, not the 

 calyx. The arl/la, though fo remarkable, is by i;o means 

 always conflant in the fame fpeeics, tliough nearly invariably 

 foil! the flowers of the fame individual phmt. 



Hufes are moflly furnifl-.cd with one central longitudinal 

 rib, though the inner j/;/)?;* of the corolla in grafles have two 

 nearly marginal o:ies. They have in mod inllaiices, befidis 

 the centra! rib, a greater or lefs number of lateral ones, all 

 likewife longitudiirdl, of great ufe in difl.ingnifiiing fpccics of 

 Poa and other difficult genera. Tliiir margin is commonly 

 thiii and more or lefs membranous or fcariofc. Some glumg 

 always remain feparate and diftinft from the feed which they 

 commonly enfold ; others are clofcly incorporated with that 

 jiart as it ripens, of whicii a curious example n-.ay be fccn in 

 Bri%a. 



Some forts of viviparous grafles exemplify the trans- 

 formation of glumes into leaves in a remarkable maimer, the 

 awn remaining at (he fummit being perhaps the only indica- 

 tion of their original nature. See jlira Uvigalti, En^I. 

 Bot. I. 2 1 02. The fame metamoqihofis of a petal into a 

 leaf is indeed not rarely fecn in a Tuhp and other cultivated 

 flowers. We have a wild fpecirr.eii of a fimilar change in 

 tl;e ylnevKre a!pir.a, part of whofe leafy involucrum is be- 

 come a perfect petal. 



Glumes are, we believe, invariably permanent, never de- 

 ciduous, till the feed ripens, when thofe of the corolla fall 

 off along with the feed, ferving the purpofe of a fcricar- 

 p:um.
