March 18, 9 a. m. — Centre of vortex near Markree. Absolute minimum ol' 

 pressure (= 29-328) at Armagh; increase of pressure — O'lO. Mean velocity 

 of the wind = 45 feet per second; greatest do. (west coast) = 50 feet. 



March 18, 9 p.m. — Centre of vortex north of the island. Absolute mini- 

 mum of pressure (= 29'371) at Portrush; increase of pressure = 0'13 inch. 

 Mean velocity of the wind = 35 feet per second; greatest do. (north-west) 

 = 50 feet. 



March 19, 9 A. m. — Rotatory movement broken up, and wind lessened. 

 Barometer fell, and wind rose again to a gale in the evening ; greatest velocity 

 (north-west) = 65 feet per second. 



March 25. — A distinct rotatory movement at 9 a. m. of this day, the centre 

 of which was a little to the north of Westport. Absolute minimum of pressure 

 (= 29'408) at Westport ; increase of pressure = 0'13 inch. The velocity of wind 

 uniform, and about 30 feet per second. The wind was very light at the pre- 

 ceding and subsequent observations, so that the progressive movement of the 

 vortex cannot be traced. 



June 11, 12. — Cyclone crossing the island from S.W. toN. E., with a velo- 

 city of about 260 miles per diem. 



June 11, 9 p.m. — Centre of the vortex a little to the west of Cahirciveeu. 

 Least pressure at Cahirciveen. Mean velocity of wind = 40 feet per second. 



June 12, 9 a.m. — Centre over the island, between Kilrush and Westport. 

 Absolute minimum of pressure (= 29"347) at Kilrush; increase of pressure 

 = 0'04 inch. Mean velocity of wind = 25 feet per second. 



June 12, 9 p. m. — Centre over the channel, to the east of Killough. Least 

 pressure at Dublin. Mean velocity of wind = 20 feet per second. 



July 27, 28. — Cyclone traversing the western coast, in direction from 

 S. S. W. to N. N. E, Velocity of wind - 30 feet per second. 



July 27, 9 a. m. — Centre of vortex west of Cahirciveen. Least pressure at 

 Cahirciveen. Greatest velocity of wind in south-west. The wind at the north- 

 eastern stations uninfluenced by the vortex.
