at the bottom. The temperature of the lower warm ."stratum could uot ])e accurately 

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

 record, having passed through a warm layer of 37' "i^ F. (2''S'J C.) and a cold layer of 

 32'-5 F. (0''-28 C.).' 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 (1 46 ni.). 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 lOO 

 fathoms was 3r-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 3r-9 ; hence it is impossilile 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 3r'9.
