SPECIFIC GRAVITY OF SEA WATER.

TABLE IX. 
SPECIFIC GRAVITY OF SEA WATER. 
In the first part of this Table the specific gravity of the surface of the sea, reduced to the 
temperature of 60®, and corrected for the error of the hydrometer, is given for every second de- 
gree of latitude. In the last it is arranged according to the passages, and the observations are 
uncorrected. In reducing them it will be necessary to apply -P .0375 for the error of the in- 
strument, at the temperature of 60“.
