1833 to May 1834, at 7 a.m., noon, and 8 p.m., and these are also 

 corrected by Dove's formula for Toronto. 



The register for York Factory, Hudson's Bay, was kept by chief 

 factor Joseph Charles, from June 1830 to end of May 1831, the tem- 

 peratures being recorded in the morning, noon, and afternoon, but 

 the exact hours of the morning and evening are not specified. They 

 have been corrected by Dove's table, on the supposition that the hours 

 were sunrise and sunset. 



The observations at Rupert House, on the east side of James's 

 Bay, were made at sunrise, an hour and a half after noon, and at sun- 

 set, and Dove's corrections have also been applied to them. 



An examination of the several columns will show clearly the effect 

 of open water in Hudson and James's Bays, in tempering the atmo- 

 sphere in the months of October, November, and even December, and 

 of the presence of ice in those seas, keeping down the summer heat.
