J CLII. Metals miner atifed by tbe Muriatic Acid. 



THE muriatic acid is more rarely found unit- 

 ed with metals. As yet it has nut been difco- 

 vered in any other than filver, quickfilver, and 

 copper. The two firft contain with it the vitri- 

 olic acid likewife *, 



{ CLII i. Metals miner alifed by tbe Aerial Acid. 



THE aerial acid is often prefent in calciform 

 metals. We meet wkh it in lead, copper, iron, 

 and zinc. Of its connexion with oiiiu* mculs 

 we have no certain intelligence. 



CLI v. Metals mineral'* fed by tbe Pbofpboric Add. 



OF all the acids, that of phofphorus is the 

 fcarceft, and has hitherto been found with a 

 fpataceous kind of lead only. 



j CLV. Metals mincraliftd by tbe Arfenical Acid. 



THE arfcnical acid, if I miftake not, is the 

 true mcntlruum of the red cobalt, that is fome- 

 times beautifully cryflailifed. It is certain, that 

 a red colour is ouing to an acid, and that, from 

 all the experiments as yet made, no other has 

 .been difcovercd.
