 Ahstrticto/a Paper on Triple Salts: 5y Mr. jb:AYX 



HE object of this paper is to show: I, that;1n trrpfeTh^ acid of 

 salts the acid is commonly divided between the bases in two *"^"'^" '-P"'" 

 equal proportions. This is the case m the triple tartrates equafly be- 

 and oxalates; in theammoniaco-raagnesian sulphate; in the f^*^^" '•^^^ 

 triple sulphate of zinc and ammonia; &c. 



2. That in a triple compound the elements united two Elements of 

 and two form possible binary compounds* For example, triple com- 



. „ ■ r,- u • J p • • PO""<^^ would 



the nitrate or ammonia, which is composed .or oxigen, ni- form binary 

 trogen, and hidrogen, when decomposed by fire yields wa- ones; 

 ter, anci gaseous oxide of nitrogen : while, on the other hand, 

 this salt is the result of two binary compounds, nitric acid 

 »nd ammonia. 



3. That the vegetable and animal substances, which are ss well as those 



composed of three or four different matters, also give rise to of^^ighercom- 



. pounds, 



binary compounds, that are possible, or generally known. 



4. That we may form an idea of the different nature of The same ele. 

 eeveral substances containing the same elements and in the 'nentsinthe 



■r 1 .L .1 . I 1 • . „samepropor- 



same proportion*. ; if we admit, that the binary products of tions may 



the elements combine in different ways with each other, or form different 



merely with one of the elements.
