2*041 inches. 



Sept. 4. — In deducing the mean variation the noon observation 

 is rejected. 



Sept. 12. — The whole of this day's observations are rejected, on 

 account of the remarkable difference of the variation. 



Sept. 28. — The evening observation is rejected, on account of 

 the unusual smallness of the variation. On that day three currents 

 of air were observed, nearly in N., S., and E. directions. The 

 wind settled easterly, and blew hard for some days.
