then examined separately. At St. Helena and the Cape, the easterly- 

 day- disturbances exceed the easterly night-disturbances, and the 

 westerly day-disturbances exceed the westerly night-disturbances. 

 These results are compared with those at Toronto and Hobarton. 



At St. Helena, although but comparatively few disturbances occur 

 during the night hours, those disturbances are almost all westerly 

 (183 disturbances, in all, occurred in nine night hours during five 

 years, of which 174 were westerly and but nine easterly). In the 

 day hours the westerly only slightly exceed the easterly disturbances. 

 At the Cape, the westerly excess is less in the night and greater in 

 the day than at St. Helena, and the night excess much greater than 

 the day excess. 



At St. Helena, the fact of the disturbances being more frequent in 

 the day than in the night is consistent in every month of the year ; 

 this appears worthy of remark when it is remembered that at St. 

 Helena the curve of the diurnal variation of the declination is pre- 

 cisely reversed at two opposite periods of the year ; in one case cor- 

 responding to the curve of diurnal variation in middle northern lati- 

 tudes, and in the other to that in middle southern latitudes. 



The mean effect of the disturbances which have been separated 

 as described, and which comprise all of largest magnitude, is a con- 

 stant westerly effect at every hour both at St. Helena and the Cape 

 of Good Hope, acting more energetically in the night than in the day. 

 At Toronto the mean effect is westerly in the day and easterly in the 

 night ; at Hobarton, easterly in the day and westerly in the night.
