65. Nitric acid holds tjie next place. When this acid, in a 

 ftate of concentration, is poured into a faturated folution of the 

 muriate, a precipitate immediately defcends. This confifts of 

 minute cryftals of the nitrate. An affufion of water reftores 

 fluidity. The liquor on evaporation affords the nitrate in cry- 

 ftals. 



66. Muriatic acid, as ufual, fucceeds the nitric. As it 

 forms a very foluble compound with Strontites, the decompofi- 

 tions accomplifhed by it are made apparent by evaporation. 

 The phofphate of Strontites is difTolved readily by this acid. 

 The liquor, when the moifture is diffipated by a very gentle 

 heat, yields cryftals of the muriate and phofphoric acid in a 

 concrete ftate. The arfenicate is taken up ftill more readily ; 

 and from the folution, by an evaporation not pufhed fo far as 

 to deprive the arfenic acid of its humidity, are obtained cry- 

 ftals of the muriate. The borate diflblved in this acid exhibits 

 phenomena fimilar to the phofphate. By adding this acid to 

 the acetite, and evaporating, we get the muriate. 



Succinic acid, if it do not rank before the two laft men- 

 tioned acids, without doubt, holds the place immediately fol- 

 lowing. 



67. Phosphoric acid comes next in order. It makes no 

 change in the combinations containing any of the acids already 

 noticed, but inftantly throws down a precipitate from the ace- 

 tite, arfenicate and borate. With regard to the two lafl of 

 thefe, care muft be taken not to add more phofphoric acid than 

 is fufficient, elfe the precipitate will be inftantly rediffolved, and 

 will elude obfervation. 



68. After phofphoric ftands acetous acid, which unque- 

 ftionably has a feebler attradtion than any of the preceding, 

 and I think a greater than the acid of arfenic, becaufe this 

 acid, dropped into, the acetite, difturbs not the tranfparency. 

 Boracic acid follows the arfenic, and laft of all comes carbo-
