at the bottom. The temperature of the lower warm stratum could not be accurately 

 determined, for the thermometers, being maximum and minimum ones, were unable to 

 record, having passed through a warm layer of 37° '2 F. (2°'89 C.) and a cold layer of 

 32°*5 F. (0 o, 28 C.). 1 The general result may be thus stated : — A cold intermediate 

 stratum of water was traced from the Antarctic Circle as far north as 54° S., where its 

 temperature was 32°-5 F. (0°'28 C.) at 80 fathoms (146 m.). Towards the south the

temperature of this cold stratum decreased till at the Antarctic Circle it was 29° F. 

 (- 1°'67 C.) from immediately below the surface to a depth of 200 fathoms (366 m.). 



1 Thus we find that at Station 156, 1975 fathoms, the surface temperature was 33°'5, the temperature at 100" 

 fathoms was 31°-9, and at 150 fathoms 34°, and below the depth of 150 fathoms the thermometer came up, showing on 

 the maximum side 34°, and on the minimum side 31°-9 ; hence it is impossible to say what the precise temperature of 

 the sea was below 150 fathoms : all that can be asserted is that it ranged between 34° and 31 0, 9.
