ALLISON — ON THE METEOROLOGY OF HALIFAX. 



87 



A fooc next morninf?. All the chief features I have mentioned 

 agree perfectly with the theories of Redfield and Reid, embodied by 

 Dove, and the observations of numerous men of science. Note 

 especially the sudden Barometrical decrease, the shift of wind with 

 the sun, and comparative lull as the hurricane's centre was nearest 

 to Halifax. The lightning flash, succeeding the rain, speaks for 

 the electric consequence of the latter. 



Let us pass on to consider this storm at other points in and 

 near Nova Scotia. From Glace Bay, Mr. Poole (whose valuable 

 record I have just had the honour of reading) sends me the follow- 

 ing notes : 4th September, 1870, 8 a. m. corrected Barometer 

 29.740; 3 p. m. 20.333, wind 11 a. m. S. E., 50 miles per hour.

During the evening the wind there was variable both in force 

 and direction, swinging back even to west. ** Force according to 

 Beaufort's scale" — where 8 represents a " fresh gale." At 9 a. m. 

 the *' Valorous" "dragged and got up steam;" at 10 a. m. 

 ** weighed and shifted berth," 



Several observers have kindly forwarded reports of this storm, 

 but our present purpose will be accomplished, and time best suited, 

 by reference to observations from a point S. E. of this. On board
