Meteorological Report for the year 1828. 



Several important inferences are to be drawn from the 

 foregoing facts. First, that the barometer has, during the 

 past year, been remarkably low, the annual mean beuig to 

 that of 1827, only as 29.81 to 30.03 ; secondly, that the differ- 

 ent seasons of the year have varied much from each ofiier, 

 the difference between the winter and the summer months 

 being .18, while in 1827 it was only .03 ; and, thirdly, that 

 the mean for the summer is the lowest, being only 29.73, 

 while in 1827, it was the highest, being 30.09, that is, higher 

 by .36 of an inch. 



The greatest height of the barometer occurred in January, 

 and was 30.62. During the month of July, the maximum 

 was only 29.86, and the mean only 29.62 ; and during the 

 succeeding months, quite to the end of the year, the mercury 

 but a few times reached the height of 30 inches. 



The minimum for the year, is 28.96. It occurred on the 

 night of the 22d of November, and was accompanied by 

 high wind and violent rain. In our climate, the barometer 

 seldom falls below 29 inches. The minimum of 1827 was 

 29.02. The range of the barometer for the two years is 

 nearly the same, and is in both very limited, being only a 

 little more than \\ inches. 



III. Winds. 



Comprehending all the winds except those which blow ei- 

 ther directly from the east or the west under the heads of 

 northerly and southerly, we arrive at the following result.
