308 ON THE METEOROLOGY OF IRELAND. 



Jan. 1, 9 A. M. Wind abated. 



Jan. 1, 9 P.M. Gale from S. W. and S. over the whole island, 

 except north-western extremity. Velocity (south-east) = 55 feet per 

 second. Absolute barometric minimum (north) = 28*975. 



In this case, therefore, there were two storms succeeding each 

 other on consecutive days, with a double fall of the barometer. 

 The direction of the wind on Jan. 1, 9 P.M. was remarkable. The 

 prevailing current was from S. W., and extended over the central 

 parts of the island ; while there appears to have been an indraught 

 towards it, from the north-western and south-eastern quarters. 



Jan. 12, 13. Storm from S. andS. W., beginning in the north* 

 west, and advancing in the direction from N. W. to S. E. Velocity 

 of wind = 60 feet per second. Least pressure in north-west 

 throughout. 



Jan. 12, 9 P.M. Gale in north-west. 



Jan. 13, 9 A.M. Storm advanced to line joining north-east and 

 south-west centres. Absolute barometric minimum (north-west) 

 = 29' 174 ; pressure least at Markree at noon. 



Jan. 27. Storm from S. and S. W. in the afternoon of this 

 day, chiefly along the western coast. Velocity of wind = 55 feet 

 per second. Absolute barometric minimum (north-west) = 29'309. 



June 15, 16. Gale from S. W. and W., on the western coast. 



June 15, 9 A. M. Wind from S. W. Velocity on western coast 

 = 50 feet per second. Least pressure in north-west. 



June 15, 9 P.M. Velocity = 45 feet per second. Absolute 

 barometric minimum (north) = 29'575. 



June 16, 9 A. M. Wind from W. Velocity = 50 feet per 

 second. 



July 13, 14. Storm chiefly in north-west, blowing at first 

 from S. S.W. and veering through S. W. to W. This appears 

 to have been a cyclonic gale, the centre of the cyclone passing to 

 the north of the island ; it is not included in the former series on 

 account of this circumstance. The velocity of the wind was greatest 

 in the north-west throughout ; the barometric pressure was least
