140 Objections to Mr. Redfield’s Theory of Storms. 
Should these specimens be considered of sufficient interest by 
scientific gentlemen, it would afford me great pleasure, on being 
informed of the fact, to exchange casts of them as soon as prac- 
ticable, for other fossil remains or casts, and to learn their opin- 
ions upon the subjects of this communication.

P. 8. addressed to the Editors, Sept. 8, 1841.—Since my com- 
munication was sent to Dr. Jackson, I have discovered among 
the fragments of bone in my possession, the body of a dentate 
vertebra, and what appears to be part of a clavicle, which, from 
their strong external resemblance in color and texture, would 
seem to have belonged to the same animal with the humerus. 
Arr. XVII—Objections to Mr. Redfield’s Theory of Storms, 
with some strictures upon his reasoning ; by Roserr Hare, 
M. D.,; Prof. of Chem. in the Univ. of Pennsylvanie. 
1. Mr. Reprienp’s idea, that tornadoes and hurricanes are all 
whirlwinds, involves some improbabilities. It requires that, du- 
ring every hurricane, there should be blasts of a like degree of 
strength coinciding with every tangent which can be applied to 
a circle. Thirty two ships equidistant from the axis of gyration, 
and from each other, should each have the wind from a different 
point of the compass with nearly equal force. The only modifi- 
cation of which this view of the case admits, is that resulting 
from the progressive motion which tends to accelerate the wie 
on the side on which this motion concurs with that of the whirl, 
and to retard it upon the other side. Moreover, as respects any 
one station, the chances would be extremely unfavorable that the 
same hurricane should twice proceed from the same quarter! 
Yet in the course of time it would be felt, at any station, to ae 
eeed from many different directions, if not from every point of 
the compass. 
2. The fact that during the same storm different vessels various- 
ly situated are found to have the wind in as many different direc- 
tions, may be explained by the afflux of winds from all quarters 
to a common focal area, as wellas by supposing them to be in- 
volved ina great whirlwind. - Mr. Redfield has —— that he
