assumed, and the directions of the wind which follow from 

 such a supposition may be compared with the observations. 



As the march of the minimum is from Brest to Cape Linde- 

 naes, France, Italy, Germany, Denmark and Russia are on the 

 southeastern side of the main path of the storm, Ireland, Scot- 

 land and Iceland are on the northwestern side, and England is 

 nearly in the middle of its course. 



On the supposition of a centripetal inflowing according to 

 Brande's view, as the phe- Fig. 1. 



nomenon passes over a sta- 

 tion on the southeastern 

 side, a wind vane at that 

 station should be seen 

 to pass successively from 

 E.N. E. through E., K 

 S. E., S. E., S. S. E. and 

 S., to S. S. W. ; and at a 

 station on the northwest- 

 em side the vane should 

 pass from N. N. E. through 

 N., N. N. W. 5 N. W., W. 



N.W.andW.,toW.S.W. 



(Fig. 1.) If, on the other hand, the storm is rotatory and turn- 



x 



ing 



in the opposite direction to that of the hands of a watch, the 



wind at a southeastern sta- 

 tion will pass from S. S. E. 

 through S., S.S.W., S. 

 W., W. S. W., and W., to 

 W. N. W. ; and at a sta- 

 tion on the northwestern 

 side, from E. S. E. through 

 E.,E.N.E.,N.E.,N.N.E., 

 N. and N.N. W. (Fig. 2.) 

 At places situated in the 

 middle of the phenomenon 

 the wind should change 

 suddenly, according to the 

 first view, from N. E. to 

 to S. W. j and, according to the
