Thefe are known by their action on the 

 above-mentioned acids, when they are joined 

 together, whereby a fermentation arifes, and 

 a precipitation enfues of fuch bodies as either 

 of them had before kept in diflblution ; 



* The dry volatile fait of amber, which difcovers itfelf to 

 poflefs the qualities of an acid, is, according to Mr. Bourde- 

 lin's experiments, communicated to the French Academy, 

 compout.ded of the acid of common fait, and a phlogifton, 

 both which fubftanccs are faid likewife to make ouc the con- 

 flituent parts of the yellow amber itfelf, though in different 

 proportion than in the fait : for this reafon, and until this 

 opinion is refuted by other experiments, the fait of amber 

 cannot be confidered as a mineral fait, that is different from 

 the others, and confequently exigent by itfelf; nor can the vi- 

 triolic acid be faid to coagulate the yellow amber.
