Ti-RU \ de Baira, the name given by fome to an earth 

 of a white colour, found about Baira, near Palermo. 



It is cfteemed a very great medicine in the cure of ma- 

 lignant fevers, and in the (topping of hemorrhages of all 

 kinds. The powder of it is commonly fold m Italy under 

 the name of Claramont-powder ; a name it obtamed from a 

 norfon who firft found out its virtues, and communicated 

 them to the world in a treatife exprefsly written on the fub- 

 jcft. Boccone, Muf. de Fific.

Terra, Chio, in the Materia Medica of the Ancients, an 

 earth of the marie kind, found in the ifland of Chio, and 

 given internally as an aftringcnt ; but its chief ufe among 

 them was as a cofmetic, the ladies efteeming it the fineft of 

 all things for clearing the fl<in, and fmoothing wrinkles. 

 What title it has to thefe qualities the world has not of 

 late ages inquired into ; but the fubftance is ftill in being, 

 and to be had in any quantities from the fame place. And 

 the defcriptions Diofcorides and Galen have left us of 

 it are fo accurate, that there is not the leaft room to 

 doubt but that the earth now found there, was the very 

 kind they ufed. It is a denfe compafted earth, yet very 

 foft, and of a texture eafily difunited and broken by 

 water.

Terra Foliata Tartari, foliated earth of tartar, is a name 

 improperly given to a neutral acetous fait, with a bafis of 

 fixed vegetable alkali ; or to a combination of the acid of 

 vinegar, faturated with the alkali of tartar, or of other 

 vegetable matter. This fait has alfo been called regenerated 

 tartar, becaufe the alkali of taitar is united with an acid, 

 which is in fome refpeCls fimilar to the acid of tartar, but 

 is in others very different. 



The terra foliata is made by pouring upon a quantity of 

 alkaline fait of tai-tar, in a glafs cucurbit, a fufficient quan- 

 tity of good diftilled vinegar, at different times, to faturate 

 all the aikah, or even a little more than is neceffary for that 

 purpofe, till the effervefcence entirely ceafes. This faturated 

 liquor is to be filtrated and evaporated to dryhefs, with 

 a gentle heat. The dry fait thus obtained is to be diffolved 

 • in fpirit of wine, and the folution again evaporated to dry- 

 nefs ; by which means a fait is obtained more or lefs white, 

 of a filky appearance, and compofed of fmall fcales or leaves, 

 whence it has been c^&e A foliata. When the fait is di-ied, and 

 wliile it is hot, it muft be fhut up in a well-clofed bottle, 

 becaufe it quickly becomes moid by expofure to air. 



When diftilled vinegar is poured upon fait of tartar, little 

 or no effervefcence is made at firft, becaufe a part of the 

 alkaline fait employed is generally cauftic, or deprived of its 

 gas, which part unites with the acid preferably to the mild 

 part of the alkali, and abforbs any gas that is extricated 

 from the latter part ; and, therefore, tiU all the cauftic part 

 of the alkali be nearly faturated, little or no effervefcence can 

 happen. But when more vinegar is added, the effervefcence 

 becomes fo confiderable, that fome of the liquor will, 

 without care, flow over the velfel. This effervefcence is oc- 

 cafioned by a large quantity of air that is difengaged during 

 tlie faturation. When the faturation is advanced to a car- 



T E R 



tain degree, the effervefcence diminifhes ; but the combination 

 of the laft portions of the acid and alkali may be facilitated 

 by frequently agitating the liquor, whicl; will renew the 

 effervefcence. The tafte of the foliated earth is (harp, pun- 

 gent, a little cauftic, and partaking at the fame time of the 

 tafte of vinegar and that of fixed alkah. It is foluble in 

 fpirit of wine, and may be decompofed merely by the aftion 

 of fire, and from it may be obtained by diftillation, a very 

 penetrating and concentrated radical vinegar. It is little 

 ufed except in medicine. Macquer's Chem. Dift. 



Preparations of this kind are given in dofcs of ten or 

 twenty grains as mild aperients, and to a drachm or two as 

 purgatives and diuretics. Lewis.

Terra Sigillata Fufca, a bole of a beautiful brown colour, 

 found in Germany, England, and America. 



It is of a denfe texture, makes no fermentation with the 

 ftrongeft acids, and if thrown into water, it foon feparates 

 into a number of thin flakes. 



The Germans give it in fluxes and malignant fevers, being 

 an excellent aftringent, and worthy to be introduced into 

 our ftiops. 



Terra Sikfiaca, Silejian Earth, a fine aftringent bole, 

 called by fome authors axungia folis. 



It is very heavy, of a firm compaft texture, and in colour 

 of a brownifh-yellow. It breaks eafily between the fingers, 

 and does not ilain the hands, is naturally of a fmooth furface, 

 and is readily diffufible in water, and melts freely into a 

 butter-Hke fubftance in the mouth ; it leaves no grittinefs 

 between the teeth, and does not ferment with acid menftrua. 

 Thefe are the charaAers by which it is known from all other 

 earths of a like colour ; it is found in the perpendicular 

 fiffures of rocks near the gold-mines at Strigonium, in Hun- 

 gary, and is fuppofed to be impregnated with the fulphur 

 of that metal. It is, however that be, a good aftringent, 

 and better than moft of the boles in ufe. Hill. 



The terra Silefiaca is alfo called terra Jigillata Strigonienjit.

Terra SoUs, a name given by the German naturalifts to 

 a kind of black fpungy earth, fomewhat approaching to the 

 nature of that Englifh black earth which we call kella-w, but 

 contjiining gold. It is not properly an ore of gold, but is 

 an earth into which fame fm.all particles of gold have been 

 wafhed from fome other place, and there detained. A good 

 microfcope will difcover thefe particles in the richer pieces 

 of the earth, and they are bright and pure, though very 

 fmall : the earth is found in fiiTures of the other ftrata, not 

 in any beds or ftrata of itfelf. It is not to be had in any 

 great quantity, nor does it contain any large portion of 

 gold.
