REPLY TO MR. HOPKINS. 491 



ate during the hours of great violence from the west, on the 

 western coast, even then there must have been an upward 

 motion of the air over England, and the generation of 

 cloud, &c., would have been the result. 



In conclusion, I would remark that the simplicity of the 

 theory, and the beautiful explanation which it gives of a 

 vast variety of phenomena, afford a strong presumption in 

 favor of its truth.
