Meteorology. A89 
The heights of January, February, October, 
November and December, are all below the 
mean; those for November and December, 
are nearly +, of an inch below the mean. 
These results were quite new tome. On 
looking over the observations in the 4th vo- 
lume of the Memoirs, however, I found that 
similar results had been obtained by Mr. 
Hutchinson, from ‘an average of 25 years’ 
observations at Liverpool, namely, from 1768 
to 1792 inclusive ; and this period being en- 
tirely anterior to the one above, is of course 
totally independent of any fortuitous events 
in that period. Mr, Hutchinson’s results, 
corrected for temperature, will stand as 
under; namely, 
Jan. Feb. March, April. May. June, 
29.75 29.61 29.82 29.79 29.78 29.79 
July. Aug. Sept. Oct. Nov. Dec. Mean. 
29.78 29.77 29.67 29.71 29.67 29.68||29.73 
Here the months March, April, May, June, 
July, and August, are all above the mean, 
and the remaining six months are all below 
it, except January. 
Wishing to have further corroboration of 
the fact, I had recourse to the Register kept 
by order of the President and Council of the 
Royal Society, and collected the whole series 
of observations of the barometer for 38
