 subject, which promises to be of general interest, as I understand 

 that shoes composed of brass or bronze, more or less like those,

HUMPHREY LLOYD, D. D., President, 

 in the Chair. 



The President communicated the following account of the 

 Cyclone of the 1 9th of November. 



" The leading phenomena of revolving storms at a given 

 place are, — 1. the veering of the wind through an angle rang- 

 ing from 0° to 180°, its magnitude depending on the proximity 

 of the centre of the cyclone ; 2. the gradual increase and sub- 

 sequent decrease of its force ; 3. the fall and rise of the ba-

 the forenoon of the 19th, it blew from the S. ; at noon from 

 S.W. ; at 6 p. m. from W. ; and between 1 and 2 a. m. of the 

 following day its direction shifted suddenly to N. N. W., and 

 it continued between N. and W. the whole of the day. The 

 barometer underwent a corresponding series of changes, the 

 mercury falling rapidly until near noon, and then rising again. 

 The least observed height was 28*290 inches, at 10 a* m. 



" I soon after received from Dr. Robinson and Mr. Cooper 

 detailed accounts of the gale, as observed at Armagh and 

 Markree, from which its rotatory character was still more evi-
