From the preceding catalogue it appears that 

 a considerable proportion of the salts of barytes 

 are anhydrous. Indeed, it would have been 

 easy to have added to the list of anhydrous ba- 

 rytes salts, if I had not been anxious to confine 

 myself to those which I have myself examined. 

 For the arseniate, tungstate, molybdate, sele- 

 niate, and sulphite of barytes are all anhydrous. 

 So also is the borate, which I believe to be a 

 compound of 



1 atom boracic acid 3 

 1 atom barytes 9*75 



12-75 



Those barytes salts which contain water seem 

 never to have more than 1, 2, or at most 3 atoms 

 of that liquid ; so that barytes in this respect 

 agrees with ammonia and potash.

 barytes, contains no water of crystallization ;
