Dec. 7, 9 A. M. — Gale from S. S. W. in the south-west. 



Dec. 7, 9 P. M. — Storm over the whole island. Greatest velocity and least 

 pressure in north-west. Velocity = 70 feet per second. Absolute baro- 

 metric minimum = 29-267. At Cahirciveen the barometer fell until 7 p. m. ; 

 and tlie wind shifted from S. to W. at the same time.* 



Dec. 9. — Storm from S.W. along the western coast. Least pressure in 

 north-west throughout. 



Dec. 9, 9 A. M. — Velocity of wind in west = 50 feet per second. 



Dec. 9, 9 P. M. — Velocity = 60 feet per second. Absolute barometric mini- 

 mum = 29-632. 



Dec. 20. — Gale blowing from S. S. W., beginning on western coast, and ad- 

 vancing to eastern. Least pressure in north and north-west. 



Dec. 20 A. M. — Gale on west coast. Velocity = 55 feet per second. 



Dec. 20 p. M. — Gale transferred to east coast. Velocity = 50 feet per second. 

 Absolute barometric minimum (north) = 29-457. At Markree there was a 

 sudden shift of the wind from S. S.W. to N. W.at 7"- SS""- p. m. 



From the foregoing facts we may draw the following conclusions : — 



1. The greater gales are much more frequent on the western, than on the 

 eastern coast, the numbers denoting the relative frequency being nearly as 5 to 1. 

 The frequency of storms is nearly the same in the northern and southern portions 

 of the island. 



2. The direction of the wind, in all the cases enumerated, was between S. 

 and W. In about half of these cases the wind blew, throughout, from the 



The following extra observations were taken at Cahirciveen on this day: —
