134 PHILOSOPHY OF STORMS. 



yond them ; especially in the extreme west and north east, 

 (see Lexington, and Montreal, and Providence, and Middle- 

 town.) 



It appears, also, what might naturally be expected from 

 the fall of the barometer within the storm, that the wind at 

 the borders, and for some distance beyond, blew inwards, 

 towards the storm. The information which we have at 

 present does not enable us to know whether the barometer 

 stood lowest in the very middle of the storm or not. If it 

 did, and there was no general currents in the atmosphere 

 to produce oblique forces, the laws of dynamics justify us 

 in expecting the wind in such case to blow inwards from 

 the circumference, exactly towards the centre, just as we 

 would expect the wind to blow outwards from the centre 

 of a storm, if there was any cause in nature to make the 

 barometer stand constantly higher at that point than in the 

 circumference. 



By casting the eye on the map accompanying the report, 

 it will be seen that there is no one point at which all the 

 arrows, if prolonged, would meet. There is, indeed, much 

 irregularity in this respect. For example, the arrow near 

 Jamestown, North Carolina, which is south of the centre of 

 the storm, still shows the wind north east ; as if the point 

 of greatest depression of the barometer, was near the south- 

 ern border of the storm ; somewhere in North Carolina ; 

 while in the northern part of the storm, the arrow for Silver 

 Lake shows the wind to be north west; as if the point of 

 greatest depression of the barometer was near the north 

 part of the storm. 



And yet, if the strong winds be considered in the extreme 

 boundaries of the storm, for example, Springfield and Wil- 

 mington, in Ohio, and in the east (all the observations from 

 the Chesapeake to New York,) these arrows being prolong- 

 ed will meet very little south of the centre of the storm : 

 and, as these winds were all strong and steady, for many
