THE DEPTHS OF THE SEA.

plateau, and about twenty miles north of the pre- 

 vious station, with a temperature of 6'9 C., and so 

 found that we had passed the limits of the cold 

 basin. 



Our first two soundings after leaving Thorshavn 

 (Stations 61 and 62) were in shallow water on the 

 Fseroe Bank, 114 and 125 fathoms, with a tempera- 

 ture of 7'2 and 7'0 C. respectively ; but the next 

 Station, No. 63, after a run of eighty miles, gave 

 317 fathoms and 0*9 C., showing that we were 

 once more in the cold region. From that point, 

 passing in a south-easterly direction across the 

 channel towards the northern point of Shetland, we 

 traversed the cold area in its most characteristic 

 form, finding at Station 64, lat. 61 21' N., long. 

 3 44' W., a depth of 640 fathoms, with a bottoi 

 temperature of 1*2 C. Here we took another 

 serial sounding, and its results corresponded generall; 

 with those of No. 52. The surface temperature 

 lower, and the temperature down to 200 fathoms som< 

 what lower ; at 350 fathoms it was a little higher : 



Surface 9- 8C.
