The observations in these high southern latitudes are very conclusive ; from the 

 zone of the most prevailing westerly winds between 50° and 60°, we pass to a region 

 of southerly and easterly winds further south. The latitudes at Avhich these winds 

 become prevailing are not the same in the whole Antarctic Ocean. South of Cape 

 Horn W. and N. AV. winds largely prevail between 60° and 62° S., and further 

 south there are no observations in these meridians. Southeasterly winds are already 

 prevailing in the meridians of the Atlantic Ocean, between 60° and 65° S., and 

 also south of Australia, while again on the meridian of New Zealand 160° to 176° 

 E., westerly winds are the most frequent. This seems to depend much on the cur- 

 rents of the sea. Where warm currents carry a high temperature further south, 

 pressure will be lower there than in the same latitudes generally, and westerly 

 winds will also extend further southward. Between 65° and 70° S. Lat., on the 

 meridian of New Zealand, there is already a slight prevalence of southerly winds. 



Between 70° and 78° S. the observations of Sir James Ross show this to be largely 

 the case. 



Thus the hypothesis of Prof. CofRn as to the prevalence of polar winds (S. and 

 E.) is shown to hold good also for the southern hemisphere, notwithstanding the 

 small number of observations we possess from high southern latitudes. As to the 

 division-line from the W. and N. W. winds of the temperate regions, it cannot yet 

 be traced with precision.
