28 ACCOUNT of a MINERAL 



nic acid, which is expelled by all the others, as appears from 

 the narration already given. 



Order of AttraBions among the Principal Acids for Strontites. 

 Strontites. 



Sulphuric acid. 



Oxalic. 



Tartarous. 



Fluoric. 



Nitric. 



Muriatic. 



Succinic. 



Phofphoric. 



Acetous. 



Arfenic. 



Boracic 



Carbonic. 



69. The attradlion of the new earth for acids ranks high. 

 For fulphuric acid, barytes has unqueftionably a fhronger at- 

 tradion than Strontites. I added barytic water to a folution of 

 fulphate of Strontites ; and though only an extremely minute 

 portion of this earthy fait be contained in the fluid, yet an im- 

 mediate milkinefs end precipitation was the confequence. This 

 earth however comes next ; for I find that, when I pour Stron- 

 titic water into folutions of fulphate of potafs, of foda, or of 

 lime, the liquor becomes turbid, and the Strontitic fulphate falls 

 to the bottom. 



70. I HAVE not afcertained how the attraction of Strontites 

 ftands with oxalic acid further than that the force of its attrac- 

 tion for this acid is fuperior to that of potafs, and confequently 

 of all thofe fubftances that are inferior to it.
