Another Paper was also read by Mr. Vernon, entitled, 
“ Examination as to the Truth of the Assertion that when 
November has a Mean Temperature above the average, it is 
usually followed by Excessive Cold between the December 
and March following.” 
In the table annexed to this Paper all the years since 
1771, in which November had a mean temperature above 
the average, are tabulated, as well as the differences from 
the mean of the succeeding months of December, January, 
February, and March. 
Following a warm November we find the following figures :

Or 91 months above the average against 70 months below

In place of a warm November preceding excessive cold, 
we find that in most of the years in which severe frosts have 
occurred early in the year, the November previous has had a 
mean temperature below the average. 
November, 1784, had a temperature 1*7° below the average, 
succeeded by December 7'8° below, January O’d 3 above, 
February 7 - 8° below, and March 7'0° below the average. 
The great frost which set in severely on January 0, 1814, 
was preceded by a November 2‘2° below the average, and 
December 2'2° below the average temperature ; January was 
8 8° below, February 4'2°, and March 5*8° below the average 
temperature. 
The cold period in January and February, 1838, was also 
preceded by a November 1*3° below the average, and
