Lower Settlement, in 1847, under the superintendence of 

 Captain Moody *, from which extracts were permitted to

The mean temperature for January 1847, was — 12°*5. 

 Observations being taken at 9 a.m., 3 p.m., and 9 p.m. 

 During twenty-two consecutive days of this period, from 

 the 5th to the 26th inclusive, the thermometer never once

 the highest 30°, giving a range of 78°. On the coldest 

 day, the 20th, when the thermometer showed — 48° at 

 the Stone Fort, and — 47° at Fort Garry, mercury froze 

 in fifteen to twenty minutes when exposed in bullet

 over so long a period as those instanced above, yet cold 

 terms of great intensity are not uncommon in Lower 

 Canada. In the excellent observatory of Dr. Smallwood's 

 at Isle Jesus, nine miles west of Montreal, the following 

 records of cold terms have been preserved f : —
