ERRATUM. 



I regret tliat, owing to the circumstances under which the last of the Meteorological 

 data were obtained, an error has crept into one of the tables, and from the table, some- 

 what into the text also. The Meteorological data for the quarter ending December 1862 

 were obtained from the Observatory, on slips of paper, from time to time, as they were 

 reduced. I was obliged in this way to anticipate their publication, as the time for reading 

 my paper was fixed for the 2d of February. Unfoi'tunately, in constructing Table B, the 

 slip of paper with the figures representing the number of rainy days, the rainfall in inches, 

 and the direction and force of the winds for November 1862, was employed in the October 

 column, the figures which ought to have been there finding their way into the November 

 column. This error in Table B still exists. 



The errors in the smaller tables of the text, arising from this transposition, are not of 

 serious import ; and indeed, if they had not occurred, the inferences drawn from the tables 

 would generally have been only more apparent. The errors do not exist in Tables A and C, 

 nor in the Diagrams ; and in order to correct the errors of the smaller tables, it is only 

 necessary to test the accuracy of the figures, by reference to one of the latter tables, in the 

 few instances in which the rainfall and winds of October and November 1862 are quoted 

 as illustrations.
