364 THE ATOMIC WEIGHTS. 



TABLE OF ATOMIC WEIGHTS. 



The following table contains the values for the various atomic weights 

 found or a(loi)ted in the preceding calculations. As the table is intended 

 for ]-)ractical use, the figures are given only to the second decimal, the 

 third being rarel}^ if ever, significant. In most cases even the first deci- 

 mal is uncertain, and in some instances whole units may be in doubt.
