92 URANIUM, ANTIMONY, CHROMIUM, &c. 



we suppose the experiments of Rose perfectly 

 exact) 9^37 ^ 6%579, a quantity which certainly 

 exceeds the truth somewhat. 



The constituents of titaniate of potash, de- 



titaniate of . . 



potash. termmed in the same way, from a mean 01 two 

 experiments, are 



Titanic acid 82-33 or 27'955 

 Potash . 17-6? - 6 



100-00 



Hence it would seem to be a compound of 5 

 atoms of titanic acid and 1 atom of potash. 

 Now, ^p- 5 = 5-591, which constitutes the 

 weight of an atom of titanic acid, according to 

 these experiments. Thus we have two atomic 

 weights of titanic acid : 



1. From titaniate of soda 

 2. potash 



Mean 



a number which does not exceed 6 by much 

 more than 1 per cent. 



(5.) Rose found that titanic acid is likewise 

 capable of combining with acids. Let us see 

 w ^ lat deductions can be drawn from these com- 

 pounds. 



Titaniate of potash was dissolved in muriatic
