that even the extreme southern record may be attributed to exceptional mixing, for prior 

 to and during the period in which Sts. 1466, 1469 and 1470 were worked, strong 

 northerly winds, reaching gale force, were experienced. 1

 Southern Pacific Ocean (Fig. 4) 



It may be mentioned that throughout the whole period of the cruise on which these 

 stations were worked, the weather was exceptionally bad, and may reasonably be 

 assumed to have favoured thorough mixing of the surface layers. As will be shown 

 later, St. 1475, which was worked in longitude 8o° W shortly after the stations discussed 



1 During the first three days the wind rarely shifted more than two points either side of north, which is 

 very unusual for strong winds in these latitudes. In the ordinary way the westerly component soon becomes 

 predominant, and the gale usually finishes in the south-west. This particular blow did not shift beyond 

 north-north-west until it moderated and held true in that quarter the day before St. 1470, which provides 

 the most southerly record of our species, was worked. Actual wind records covering this period were as 

 follows :
