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 
Feroe 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°9C., 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 bottom 
temperature of —1°2C. Here we took another 
serial sounding, and its results corresponded generally 
with those of No. 52. The surface temperature was . 
lower, and the temperature down to 200 fathoms some- 
what lower; at 350 fathoms it was a little higher :—
