 cury. 



The experiments related in this section, con- 

 stitute the best of a very great number which I 

 have made upon this difficult metal. They leave Atomic 

 no doubt on my mind that the atomic weights of 

 mercury and its compounds are as follows : 





At the same time, it is proper to state, that I 

 have made no attempts to analyze the iodides of 

 this metal.

OF THE ATOMIC WEIGHT OF SILVER. 



I HAVE already stated an experiment in page 105 

 of this work, from which the atomic weight of
