coil was reeled out to 800 fathoms, and the readings taken as it 

 was drawn up. 



In the last series of observations in reeling back the cable ; the 

 temperature at 50 fathoms was 54'f>, and fell to 51 '5 at 30 

 fathoms. Immediately after another series was taken with the 

 Miller-Casella thermometer, and the same increase of tempera- 

 ture from 30 to 50 fathoms was observed. The cable was 

 lowered three separate times to 50 fathoms, and the readings 

 being taken both when lowering and reeling in with the following
