DISSOLVED GASES. 
The depth is given in meters, the temperature in degrees centigrade, and the gases in cubic centi- 
meters per liter of water. The last column shows the per cent of satmration of the oxygen. In the 
free carbon dioxide, a minus sign indicates that the water was alkaline, a plus sign that it was acid, 
and neut. that it was neutral to phenolphthalein. 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.
