ts Mr. Redfield’s Reply to Dr. Hare. 299 
Per. XIl.—Reply to Dr. Hare’s Cuesiee & to she Whirlwind 
Theory of Storms; by W. C. Reprrexp. 
An article entitled “ Objections to Mr. Redfield’s Theory of 
Storms, with some strictures on his reasoning ; by Roserr Hare, 
M.D., Prof. of Chem. in the Univ. of Pennsylvania,” which 
lasitewe in the last number of this Journal, and is also found in a 
modified form in the London, Edinburgh and Dublin Philosoph- . 
ical Magazine for December, has given occasion for the notes 
and remarks which follow. 
The several series of facts and observations, showing both the 
rotary and progressive movement of great storms, which I have 
published, together with those which have also been adduced by 
Reid, Milne, Dové and Piddington,* are deemed sufficient to es- 
tablish the whirlwind character of these storms. In the absence, 
therefore, of contravening facts of a reliable character, it seems 
incumbent on an objector to set aside these facts and observations 
as unfounded and inaccurate, or to show that the results which 
they appear to establish have been deduced erroneously. This 
task Dr. Hare has not attempted; and I might therefore have 
been excused from replying to his objections and strictures ; as 
these cannot affect the results which it has been my chief aim to 
establish. 
But the nbecceniiens which I have published extend als to the 
So-called tornado or water-spout, and with similar results :+ while 
Mr. Espy and Dr. Hare have each in turn advanced his the- 
ory of tornadoes and storms, founded on a@ priori reasoning or 
Speculation, and on alleged deductions from phenomena observed. 
Hence, perhaps, originates this fourth attempt, from one or other 
of these sources, to discredit the results of my principal inqui- 
ries ; being, however, the first from Dr. Hare.
