Foulke and Rensselaer Bay resultants are also computed for the vAimher of miles 

 travelled by the wind, but they do not differ much in direction from those com- 

 puted for time only ; and at both these places monsoon influence can be perceived. 

 At the former it is southwesterly in summer and northeasterly in winter. At the 

 latter it is northwesterly in summer and southeasterly in winter. 



Z01\E IVo. 4. 



Latitude 70° to 75° North. 



The data for the study of the winds of this zone consist of observations made in 

 the following portions of it : — 



1st. Arctic seas of North America and Greenland, and islands in the same, for 

 an aggregate period of more than twelve and a half years, beside the observations 

 on Baring's Island by McClure, which were not regularly recorded, but appear only 

 in the form of incidental allusions. 



2d. Western Greenland, at Upernavik, for eight years. 



3d. Arctic Ocean, between Greenland and the coast of Norway, for an aggregate 

 period of 432 days. 



4th. Finmark, at tvvo stations, for periods severally of eight and fourteen years. 



5th. Arctic Ocean, north of Europe, for two months. 



6th. Eastern part of Nova Zembla for four and a half years. 



7th. Northern Siberia and the adjacent seas for an aggregate period of over two 

 and a half years, besides numerous notices and remarks by Wrangel in regard to 

 the winds of this part of the Arctic Ocean. 



The aggregate length of time during which observations were regularly recorded 

 in this zone, and incorporated into this work, is therefore over 51 years. 



(Nos. 1 to 14.) Western Arctic Ocean and its Islands.
