490 PHILOSOPHY OF STORMS. 



He does not pretend to deny that if the air did rise in 

 the centre it would form cloud by the cold of expansion, for 

 this seems to be generally admitted, and is demonstrated 

 by experiment. Nor does he contradict Mr. Espy's great 

 principle, on which his whole theory is founded, one which 

 he demonstrates both on acknowledged chemical principles, 

 and by experiments with the nephelescope, that latent 

 caloric enough is given out into a great storm cloud by the 

 vapor condensed in forming the cloud to cause the barome- 

 ter to fall as much as it actually does in great storms. 

 Now, when it is known that the storm was very violent 

 from the west as early as nine o'clock, on the coast of Ire- 

 land, arid that the wind continued to blow from that quar- 

 ter for several hours, while at the same time, on the eastern 

 coast of England and Scotland, the wind was getting round 

 to the eastward, increasing in violence at Hull, and blowing 

 a gale south east at Bridlington, I would ask Mr. Hopkins 

 what became of the mighty quantity of air rushing towards 

 England across Ireland for four or five hours? 



Did it spread out at the north and south? So far from 

 this being the case there was a violent wind all night all 

 along the southern coast of England, from the southward. 

 And at Aberdeen, George Innes, in his journal, says, the 

 wind, from being calm before, began to blow heavily from 

 the north west towards night, and in the early hours of 

 Monday, nearly a hurricane N. N. W. And all the ac- 

 counts from the west of Scotland give the wind north of 

 west after the change. The air, therefore, which blew with 

 such violence from the west on the western coast of Eng- 

 land till about midnight, must have gone upwards before it 

 reached the eastern coast ; and all the phenomena of cloud 

 forming, and giving out latent caloric, as demonstrated by 

 Mr. Espy, must have taken place. 



Indeed, as Mr. Espy says in his lectures, if the wind had 

 even been from the west on the eastern coast ; but moder-
