18 REPORT OF THE SECRETARY. 



and southerly until they reached the longitude of 9G^ west; thence 

 returned along Barrow's strait to the east, and southerly down Prince 

 Regent's inlet to the mouth of Bellot strait, where, at a place named 

 Port Kennedy, the vessel remained from the 27th of September, 1858, 

 till August 9, 1859. From this point various excursions, with sleds, 

 were made in different directions. The expedition returned to Eng- 

 land in September, 1859. 



During the whole continuance of the expedition a series of meteor- 

 ological and other observations was made. Those of the first year 

 were taken while the vessel was in a constant state of motion either 

 sailing through the water, or drifting down Baffin's bay with the im- 

 mense field of ice. Those of a considerable part of the second year 

 were made while the ship was stationary at Port Kennedy, 



The observations have all been arranged in four parts : the first 

 relating to temperature ; second, to winds; third, to atmospheric 

 pressure; fourth, to miscellaneous phenomena, such as auroras, 

 weather, specific gravity of sea-water, ozone, <fec. 



In the discussion of the records, the whole series has been divided 

 into two groups, one of which is referred to a point in Baffin's bay, 

 and the other to Port Kennedy. 



The discussion of the temperatures of each group embraces — 

 1st. Diurnal variation. 

 2d. Annual variation. 



3d. Relation of temperature to the phases of the moon. 

 4th. Temperature of different winds. 

 5th. Temperature of sea-water. 

 The discussion of the winds includes — 



1st. Resultant direction for each month, season, and year. 

 2d. Velocity for each of these periods. 

 3d. Frequency of winds from different quarters. 

 4th. Quantity of air which passed over the station, 

 oth. Rotation of the winds. 

 6th. Investigation of particular storms. 

 A similar series of discussions is also given with regard to the barom- 

 eter. These discussions have all been made at the expense of the 

 Institution by Charles A. Schott, of the Coast Survey, according to the 

 methods adopted by Sir John Herschel, in his admirable article on 

 meteorology in the last edition of the Encyclopedia Britannica. They 

 bring out a number of interesting results, particularly in regard to the 

 rotation of the wind, the effect of the moon on the temperature, and the
