Forchhammer first definitely proved, what indeed was 

 almost a priori evident, that, although the salinity of the 

 ocean varies with locality, season, depth, etc., yet the 

 ratio of dissolved salts to one another remains practically 

 constant. Of course slight variations are only to be 

 expected in coast waters, especially if landlocked or if 

 receiving extensive river drainage, but in deep sea-waters 

 the circulation of ocean currents etc., could fairly certainly 

 be reckoned on to thoroughly mix the dissolved salts. The 

 detailed work of Professor Dittmar 1 (undertaken in con- 

 nection with the Challenger Expedition) was especially
