TAR 



Tartrite of Soda, a fait produced in fmall needled cryf- 

 tals from a due cvaporatii)n of tartareous acid faturatcd with 

 foda. This fait, formerly confounded with the Rochelle 

 fait, OT fill Riip.'IL'iifts, is not very foluble in water ; however, 

 when tartrite of potalh is added to this fait, each in faturated 

 folution, large cryftals of the triple tartrite, or Rochelle 

 fait, are immediately depolited. 



k. fuper-lartrite of foda is formed by partially faturating 

 tartareous acid with foda, and alfo by adding a ftrong acid 

 to the faturated tartrite, which, being lefs foluble tlian the 

 faturatcd compound, precipitates. It is obferved, however, 

 that tartareous acid will not form (vifibly) an acidulous tar- 

 trite, when added to the fulphate and other falts of foda, as 

 it will do wit!i the falts of potafli. 



TARrRlTE o/'y^mmOHW, a fait formed by faturating the 

 tartareous acid with ammonia or its carbonate. This fait 

 cr)-ftallizes readily, and is decompofed by the fixed alkahes 

 and alkaline earths. 



h. fuper-larlnle of ammoma is formed in a fimilar manner 

 to the luper-tartrite of foda, and with the fame exception 

 of the acid not vifibly decompofmg the other ammoniacal 

 falts. See Ammonia, and Tartrate of Ammoma under Salts. 



Tarthites, Earthy. See Earthy Salts. See alfo Tar- 

 trate of I.'ime under Lime. 



The tartrite of lime is produced in a white precipitate, by 

 adding tartareous acid to any foluble fait of lime, or lime 

 to a foluble tartareous fait. Although this fait is infoluble 

 in mere water in a common temperature, it diffolves readily 

 in an excefs of its own, or of any other acid that does not 

 decompofe it, fuch as the acetous or muriatic. It is alfo 

 rendered foluble in water by the addition of potafh. When 

 it is heated flrongly in an open fire the whole acid is con- 

 fumed, and carbonate of hme remains. 



Tartrites of Barytes and Strontiam, are formed in the 

 fame manner as tartrite of lime ; but they are not fo infolu- 

 ble in water as this fait ; and the tartrite of ftrontian will 

 even cryftaUize from its hot-faturated folution by cooUng. 

 With magnefia and alumme this acid forms very foluble com- 

 pounds, which do not cryftaUize by evaporation, but dry 

 up into a gummy mafs. Aikin's Dift.

TARVIN, or Tarven, in Geography, a townfliip and 

 parilh in the hundred of Edilhury, and county palatine of 

 Chefter, England, is fituated on the London road, five miles 

 N. by E. from Chefter. It had for fome time a weekly 

 market, procured by fir John Savage, in the reign of queen 

 Ehzabeth ; but this has been long difcontinued. An annual 

 fair was alfo held here till within the laft thirty years, but was 

 then abolilhed. Tarvin was one of the parliamentary gar- 

 rifons during the civil wars : in Auguft 1644, it was a Ihort 

 time in the pofleflion of the royahfts ; but in the following 

 month it was retaken for the parhament, and fortified with 

 ftrong works. This and Nantwich were the only garrifons 

 in Cheftiire not abandoned on the reported approach of the 

 king, in May 1645 ; and the parhament retained it till the 

 end of the war. A grainmar-fchool was founded here in 

 the year 1600. John Thomafen, a celebrated penman, was 

 mafter of this fchool thirty-fix years in the early part of the 

 laft century. On the outfide of the parilh church is an in- 

 fcription to his memory, ftating that he " highly excelled in 

 all the varieties of writing, and wonderfully fo in the Greek 

 charafter. Specimens of his ingenuity are treafured up in 

 the cabinets of the curious and in the pubhc hbraries through- 

 out the kingdom." The townfhip of Tarvin was ftated in 

 the population return of the year 181 1, to contain 180 

 houfes, occupied by 921 perfons. The parifli is very ex- 

 tenfive, and includes 1 1 townfhips, containing in the whole 

 2877 inhabitants, the number of houfes being 525. — Ly-
