380 Meteorological Observations, 



will be found to bear some relation to the range of the barome- 

 ter. In the column of easterly storms, are included those which 

 were unaccompanied with rain, amounting to about one third 

 of the whole number. The column of electrified clouds indicates 

 the number of days on which electrical phenomena occurred, to 

 any considerable extent. In some remarks, published in the 5th 

 No. of this Journal, the manner of obtaining the results in most 

 of the remaining columns, is explained. For the sake of compari- 

 son, the summary for the year 1830 has been added.
