184 METEOROLOGICxiL OBSERVATIONS 
The results of the preceding journal I shall now state, 
confining myself at present to the recording of the simple 
facts as they appeared on calculation. i)r Brewster sug- 
gested to me the best mode of drawing the most interesting 
results, which I followed with all possible care and atten- 
tion. 
Having taken the averages of each twenty-four hour>s' 
observations (which were as follows) 
1822, July, 
August, 
September, 
October, 
November, 
December, 
1823, January,

and the mean of these, (which proved to be 48°.71-}-), I cal- 
culated the average temperature of each hour in the twenty- 
four, as it occurred throughout the twelve divisions of the 
series- This gave

The mean of these temperatures, again, is 48°.734- 
varjing only .02-}- from the mean of the whole, obtained 
by taking the average of the mean temperature of each 
twenty-four hours'* observations. In this manner, I got 
data for future calculations, the final results of which I 
shall now state. In doing so, I propose to use the mean
