Discussion op the Preceding Table. 
In going over the 77 reports embodied in this table, we see that although the con- 
centration of the waters is- very different, the percentage composition of the dissolved 
material is almost the same in all cases ; the mean values being as follows : — 
(In 100 parts of Total Salts.)
