(Plate X. Figs. 1, 2, 3.) Mean velocity of wind on the 29th = 45 feet per 

 second.* 



Sept. 29, 9 A. M. — Centre of vortex off the south-western coast, to the west 

 of Cahirciveen. Force of wind greatest at the same station at 3 a.m. ; but the 

 barometer continued to fall until noon, when the pressure was 28'970. Increase 

 of pressure = 0"22 inch. Greatest velocity of wind (north-west) = 60 feet per 

 second. 



Sept. 29, 9 p. M. — Centre over the island, about midway between Kilrush 

 and Dublin. Absolute minimum of pressure (= 29030) at Markree ; increase of 

 pressure = 0-12 inch. Least pressure in south-east at 6 p.m. Greatest velo- 

 city of wind (north-east) = 55 feet per second. 



Sept. 30, 9 A. M — Centre near Malin Head, at northern extremity of the 

 island. Absolute minimum of pressure (= 29'020) at Portrush ; increase of 

 pressure = 015 inch. Mean velocity of wind = 35 feet per second; greatest 

 do. (north-west) = 55 feet. 



Sept. 30, Oct. 1.— Cyclone moving apparently in curvilinear path, its course 

 being at first from W. to E., until it reached the centre of the island, and 

 afterwards from S. S. W. to N. N. E. Mean velocity of wind between 25 and 30 

 feet per second.
