 flill fleering NNE: latitude obferved at noon 65° 18' 

 17^''. At three in the afternoon, founded with 300 fa- 

 thom of line, but got no ground. Longitude by the

20th.. Almoft calm all day. The water being per- 

 fedly fmooth, I took this opportunity of trying to get 

 foundings at much greater depths than I believe had ever 

 been attempted before. I founded with a very heavy 

 lead the depth of 780 fathom, without getting ground; 

 and by a thermometer invented by lord Charles Cavendifh 

 for this purpofe, found the temperature of the water at 

 that depth to be 26° of Fahrenheit's thermometer; the 

 temperature of the air being 48'
