ATOMIC WEIGHTS 



541 



TABLE OF ATOMIC WEIGHTS. 



In the following table the results of the foregoing calculations are 

 brought together, each atomic weight being rounded off to five significant 

 figures, or sometimes fewer. For convenience, the values are given in 

 two columns, referring to the two ultimate standards, = 16 and H = l. 

 Many chemists prefer the latter, and their wishes are, in a work like this, 

 entitled to respectful consideration :
