Mr. Redfield’s Reply to Dr. Hare. 301 
The first of these conditions is verified by observation, 
cept as I have shown that the changes in a regular whirlwind 
iin will not, in the true wind of the gale, be likely to exceed 
sixteen points of the compass at any one station. It will be diffi- 
cult, however, for Dr. Hare to show, that the regular changes in 
itvobreatve whirlwind storm, as truly exhibited at any fixed 
station, should run through every point of the compass; although 
this may sometimes happen to a ship moving in the storm. 
Dr. Hare does not appear to perceive, that the several condi- 
tions above referred to, are for the most part, no more predicable 
of the whirlwind storm, than of the affluent theory of storms 
which he advocates. 
Dr. Hare states, that “the fact that during the same storm dif- 
ferent vessels variously situated, are found to have the wind in 
as many different directions, may be explained by the affiux of 
winds from all quarters to a common focal area, as well as by sup- 
posing them involved in a great whirlwind.” This might be 
true, as [ have virtually stated elsewhere, provided that the di- 
rection of the wind at such vessels was found, at a given time, 
to be towards such a “focal area ;” which does not happen: the 
observed differences of the winds from these centripetal direc- 
tions being nearly equal to ninety degrees, (or a right angle,) 
as has been repeatedly shown.* 
T have formerly stated that “I have observed in the effects of the 
New Brunswick tornado, numerous facts which appear to demon- 
Strate the whirling character of this tornado, as well as the inward 
tendency of the vortex at the surface of the ground.”+ But Dr. 
Hare thinks, “that the survey of Bache and Espy shows that it 
Would be inconsistent with the facts to suppose such motion, un- 
lets as a contingent result.”” Now, without inquiring whether the 
constant whirling action to which I alluded be a contingent or a 
necessary result, it is proper to notice, that the great question be- 
tween us is and has been, have storms a gyratory character? 
To me, the facts established by all the strict observations which 
have been made and properly stated, proclaim the affirmative. 
We shall probably find, on a strict examination, that even the
