LIX. On Dr. Hare's "Additional Objections" relating to 

 Whirlwind Storms. By W. C. Redfjeld*. 



T N my reply to Dr. Hare's first series of " Objections " and 

 ■*■ " Strictures," I attempted to show that these could have 

 no. weight or efficacy in disproving the whirlwind character 

 of violent storms and tornadoes; and, furthermore, that con- 

 vincing evidence of whirlwind action in the tornado of New 

 Brunswick was found in those very facts which he had set 

 forth and relied on for disproving its rotation f. 



Besides correcting, on that occasion, certain grave errors 

 into which my opponent had fallen, I also referred to the ad- 

 ditional proofs of rotation which are found in my published 

 survey of the effects of this tornado J. This was deemed suf- 

 ficiently conclusive in replying to Dr. Hare, who had chosen 

 to " enter the lists " as my assailant and in support of his own 

 and Mr. Espy's notion of the centripetal course of the wind 

 in these storms; for the effects produced by the New Bruns- 

 wick tornado had been greatly relied on by each of these 

 writers, as proving such centripetal course in the wind of tor- 

 nadoes. 



At that time I possessed, in my field-notes and surveys, 

 abundant evidence of a constant rotative action in several 

 other tornadoes, and plans or diagrams which exhibit portions 

 of this evidence had long been prepared ; but I saw no defect 

 in the proofs of rotation previously shown that required their 

 publication. 



One of the tornadoes which I had thus prepared to illus- 

 trate, was that which passed near Providence in 1838, some 

 account of which had been published by Dr. Hare; and, as 

 partiality for his own electrical hypothesis may have induced 

 him to engage in this controversy, I now refer to a paper con-
