300 Mr. Redfield’s Reply to Dr. Hare. 
Moreover, I have sometimes ventured to offer summary skete 
es of other results or conclusions which seemed to follow from — 
the above mentioned and other developments, which came under 
notice in pursuing my meteorological inquiries.* These sketches 
or conclusions were given, partly as notifications and partly be- 
cause I was not willing it should appear in after years, that such 
results or conclusions as I have noticed had been overlooked in 
conducting my examinations. These inceptive statements seem 
to have occasioned many of the “strictures” and criticisms which 
Tam now to notice. ; 
Dr. Hare says that my “idea that tornadoes and hurricanes are 
all whirlwinds, involves some improbabilities,” and that it requires 
that ‘‘during every hurricane, there should-be blasts of a like de- 
gree of strength coinciding with every tangent which can be ap- 
plied to a circle,” and that “ thirty two ships equidistant from the 
axis of gyration, and from each other, should each have the wind 
froma different point of the compass with nearly equal force.” 
The only modification he admits, “is that resulting from the pro- 
gressive motion which tends to accelerate the wind” on one side, 
“and to retard it upon the other.” 
I could never have imagined that any “ idea” of mine necessa- 
rily involved the conditions here specified; and if the fact be such, 
Dr. Hare would have rendered some service by making it manifest. 
The modification admitted by him, vitally important as it is, shows 
only one of the conditions which would doubtless prevent any 
such perfect symmetry of results as he demands; to say nothing 
of the practical error of supposing that the course of the wind in 
a whirlwind must coincide with the tangents of a circle. He 
alleges also, “that as respects any one station, the chances would 
be extremely unfavorable that the same hurricane should twice 
proceed from the same quarter.” If by this is meant that the 
changes of wind at any one station in the same gale, are not 
likely to come back to the same point of the compass from which 
it had before blown, except by an extraneous force or influence, 
we'shall in this be able to agree. He states further, that “in the 
course of time it would be felt, at any station, to proceed from 
many different directions, if not from every point of the com-
