METEOROLOGICAL OBSERVATIONS. 



619 



through the mean vahie about 8 a.m. and 8 p.m. ; the whole daily 

 range being about 4" F. 



The observations at Port Foulke do not bear out the statements 

 of other observers, that it is coldest about the time of full moon. 



Daily Range of Barometer. 



The barometer is at its lowest between midnight and 4 a.m., 

 and then rises slowly until 8 a.m., but descends again until noon ; 

 it then rises to its highest point at 4 p.m., and then descends to 

 its lowest value at midnight. 



The yearly maximum occurs in April at Port Foulke and Port 

 Kennedy, and in May at Van Rensselaer. The minimum occurs 

 in October at Port Foulke and at Port Kennedy, and in September 

 at Van Rensselaer. At Port Foulke another maximum was also 

 observed in November, and a smaller maximum at Port Kennedy in 

 th« same month. 



" The resulting direction of the wind at Port Foulke is N.E. 

 " (true), Avhich agrees with the general movement of the atmosphere 

 " in Arctic regions, but the resulting direction at Van Rensselaer - 

 " is S.S.W. nearly." (Sm. Con., vol. 15, p. 237.) In June, July, 

 and August the winds on the West Greenland coast are variable, 

 but throughout the other nine months of the year they are mostly 

 from the north-east. The winds which prevail the least are the 

 south-west in January and the north-west in July. 



In proceeding north on the West Coast of Greenland, the 

 difference of temperature between the extreme seasons gradually 

 increases thus : —

Port Kennedy and Sabine Island are added for comparison, and 

 it will be seen that the range at Wolstenholme Sound and at 

 Sabine Island is nearly the same.
