I shall now arrange these different bodies in the three classes to 
which they respectively belong, reducing the specific gravities in the 
first column of the preceding table to the numbers which will repre- 
sent them when we suppose the specific gravity of a volume of 
oxygen gas to be 1. bab Fei 
Set First.—Bodies having the weight of their atoms equal to the 
specific gravity of their volumes :—
