In the case before us, I can find no strict observations directed 
to this point, except my own; which, on the afternoon of the 
6th, show the wind from N. N. E. and the storm-scud from N. E., 
ae the not unusual difference. 
_ Acceteratep Roration 1x THE Bopy or THE Storm.—We 
find in this case, as in other storms, a greatly accelerated velocity 
of rotation in the wind as we proceed from the exterior limits 
towards the axis of the gale, till we reach that interior portion 
where the destructive force of a hurricane was exhibited. This 
is in accordance with the universal law of vortical revolution, 
which seems no other than the law of equal areas in equal times. 
“ Like the vortical involution, this acceleration finds its principal 
limit externaliy to the region of central inactivity in a storm ; 
and, in some storms and localities, at a very great distance from 
the geographical center of revolution; the active portion of the
