BULLETIN OF THE BUREAU OF FISHERIES 
Table XIII. — Distribution op Heat to the Several io-Meter or s-Meter Strata. 
[In the tables the upper figures of columns 2 and 4 show the number of calories per square centimeter of surface of the lake 
necessary to raise the temperature of the water from 4 ° to the summer temperature in 1910 and 1911 , and the remaining figures 
show the number of such calories remaining at the several depths. Columns 6 and 7 show the number of calories present at each 
depth per square centimeter of the area at that depth. They are derived from the numbers of columns 2 and 4 by dividing them 
by the per cent of area given in column 3 , tables xv-xvii. Colunms 10 and 12 show the number of calories per square centimeter 
of surface left between the depths specified. They are computed in the same way as the data in table xii. The data for Otisco 
and Canadice Lakes refer only to 1910 .]
