B. The letter b placed over any figure, signifies that the Mercury was so many degrees below 0. Thus on the 31st of December 1765, you find b15, b29, that is, 15 and 29 below zero; or 47 and 61 below the freezing point. Again, on the 5th of January 1766, the numbers are 25 and b25, which is 25 above, and 25 below 0. So that the difference between the highest and lowest degrees of heat on that day, is 50 degrees. On the 27th of May (1765), when the Mercury rose to 85, and fell no lower than 58 (the mean of which is 71½) at Quebec, at a place down the river, called Mont Louis, was a heavy storm of snow, which continued the whole day: the distance of these places is about 260 miles.
