degree below it. The numbers therefore 

 which have no o before them, fignify the 

 upper degrees. Some examples will make 

 this ftill more intelligible. On the 17th 

 of December it is remarked, that the ther- 

 mometer, at eight o'clock in the morn- 

 ing, was at 02.5. It was therefore at 2 

 degrees and T V, or half a degree, below 

 the freezing-point ; but at two in the af- 

 ternoon, it was at 00.0, or exactly upon the 

 freezing-point. If it had been 00.3, it 

 would have fignified that the thermometer 

 was fallen A of a degree below the freezing- 

 point ; but 0.3 would fignify, that it was 

 jifen T % of a degree above the freezing- 

 point. Thus likewife 03.0. is three de- 

 grees below the freezing-point; and 4.0. 

 four degrees above it. 



The numbers in the columns of the 

 winds fignify as follows : o, is a calm ; 

 1, a gentle breeze ; 2, a frefh gale ; 3, a 

 ftrong gale ; and 4, a violent florin or hur- 

 ricane. When, in fome of the laft tables, 

 the winds are only marked once a day, it 

 fignifies that they have not changed that 

 day. Thus, on the 2 1 ft of December, ftands 

 N. o fair. This fhews that the weather- 

 cocks have turned to the north all day; 

 but that no wind has been felt, and the 

 fky has been clear all the day long.
