BULLETIN OF THE BUREAU OF FISHERIES. 
TABULAR DATA COVERING ALL LAKES EXAMINED. 
Table 11. — Depth, temperature, dissolved gases, and transparency of lakes examined. 
[The depth is given in meters, the temperature in degrees centigrade and Fahrenheit, and the gases in cubic centimeters 
per liter of water. The last column shows the per cent of saturation of the oxygen for a few of the important lakes. In the free 
carbon dioxide column a minus sign indicates that the water was alkaline, a plus sign that it was acid, a “neut.” that it was 
neutral to phenolphthalein, and 7 ‘ Tt.,” a trace. The degree of alkalinity or acidity is indicated by the number of cubic 
centimeters of carbon dioxide that would have to be added or removed to make the water neutral.]
