have been pl(jtted in figure 35. In view of Meinardus's opinion that the stations on the 

 edge of the Antarctic Continent are under cyclonic influence this is an important result 

 and one which will prove useful when we come to discuss the pressure and wind conditions 

 of tlie Antarctic as a whole. To make the investigation complete the observations taken

during two years on the drift of the Fram (1894 and 1895 between latitudes 79° and %b\'^ 

 N.) were analysed in the same way. The first group, — 4 miles per hour, contained only 

 8'7 per cent, of the observations, while the second group was the maximum with 41-4 per 

 cent., thus the frequency curve in north polar regions is of the cyclonic type.
