* The observations on the bottom temperature were obtained by sinking a closed tin can to the bottom 

 and keeping it there at all times except at the moment of observation, when it was drawn up, the cover 

 ronuiv.d, and the bulb of the thermometer inserted in the water. The depth at the point of oli.servation 

 -wa.s from rii;lit to ten feet. The surface temperature was measured at the same place as the bottom 

 temperature, and the position was changed several times during the summer.
