Another fact observed during the past year, is that of the " rotation" of the 

 wind. The hiw of rotation, noticed by Dr. Dalton, and more fully developed 

 by Redfield and Dove, that the winds have a rotation from the north to the 

 north-east, then east, south-east, and so through the points of the compass 

 round to the north again, was sustained, with few exceptions. The number 

 of circuits which have been made in this manner during the year, I am unable 

 to state. Not thinking of this law of " rotation" of winds, until reminded of 

 it by the fact here observed, proper care with respect to this point was not had 

 in the observations. In the absence of mountains to act as disturbing local causes, 

 we may have here an opportunity of establishing or verifying this law in this 

 country. Our strongest winds are those from the south-west; next to this the 

 west and north-west. The wind very seldom blows for any length of time from 

 the north-east or east.
