Table III. — Specific Gravity, Chlorine Content, and Salinity of Water Samples from 

 Bottom of St. Mary Bay Stations in 1915, 



The density of each -water sample "was determined at room temperature by means 

 of a delicate hydrometer, and corrected to read at 15.56° C. by Buchanan's Diagram.^ 

 The methods of analysis and of calculating the salinity were those of Dittmar.i
