Note. — To obtain the mean thermometer temperature, the lengths 
in the first column were multiplied by the corresponding tempera- 
tures in the third column, and the sum of the products divided by 
the total length. 
It will be seen from the previous statement that the short length 
of shallow water at each end of the line is only sufficient to raise 
the mean temperature one-third of a degree above the minimum
