* 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 ol)servatinn, when it was drawn up, the cover 

 removed, and the bulb of the thermoinoter inserted iu the water. The depth at the point of oh.servation 

 was from eight 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.
