46 OF THE ATOMIC THEOJIY. 



1*75 azote combines with 1, 2, 3, 4, 5 of oxy- 

 gen. Hence 



1. ^1-75 azote + 1 oxygen = 2-75 protoxide of azote. 



2. 1-75 + 2 =3-75 deutoxide of azote. 



3. 1-75 4" 3 = 4'75 hyponitrous acid. 



4. 1*75 +. 4 = 5-75 nitrous acid. 



5. 1-75 +5 = 6-75 nitric acid. 



(4.) After determining in this way, the atomic 

 weights of some of the most common and impor- 

 tant acids, I examined the neutral salts which 

 these acids formed by uniting with the salifiable 

 bases, and determined the proportion between 

 the weights of the acid and base in each. From 

 this I deduced the atomic weight of the base. 

 Thus, knowing that the atomic weight of sul- 

 phuric acid is 5, and that sulphate of potash is a 

 compound of 



Sulphuric acid 5 

 Potash 6 



- 



11 



I drew as a conclusion, that the weight of an 

 integrant particle of sulphate of potash is 11, 

 and that an atom of potash weighs 6. By this 

 method, I determined the atomic weights of 

 most ofthe salifiable b as es. 



(5.) I now combined some .of the most com- 

 mon and important of these salifiable bases with 

 the other acidsthus forming a new set of 

 neutral salts. These were analyzed with great
