WINpDs oF EUROPE. 
By Purny EARLE CHASE. 
(Read before the American Philosophical Society, June 16, 1871.) 
In my desire to give proper weight to considerations which favor the 
hypothesis of normal cyclonic currents, I stated in a recent communica- 
tion to the Society (March 17, 1871), as one of the admitted facts, ‘that 
most of the European winds are cyclonic.’’ 
Further study has satisfied me that this admission is altogether too lib- 
eral, and that, although a majority of the European winds are cyclonic, 
the majority is not a large one. The daily weather maps of the French 
“Bulletin International,’”? and the Quarterly Weather Reports of the 
British Meteorological Office for 1869, seem to show conclusively that in 
France and Great Britain, anticyclonic are nearly as frequent as cyclonic 
currents, and that it is only by a discussion of continuous records that the 
prevailing cyclonism, such as is indicated in the following table, can be 
demonstrated. 
I have deduced the average direction of the winds from the tables in 
Coffin’s ‘‘ Winds of the Northern Hemisphere.’’ Those marked (C) were 
computed by Prof. Coffin; the others were obtained by combining, 
with some regard to weight, the observations which he records for the 
respective districts.
