METEOROLOGV. 



Communicated hy the Right Hon. Lord Gray. 

 To Mr. Tillock. 



Sir, — I have sent inclosed for insertion in your Philoso- 

 phical Magazine, two Meteorological Tables tor last year ; 

 the one kept at Gordon Castle, the residence of the Duke 

 of Gordon, the other at Kinfauns Castle near Perth. 



I think, a more general publication of such results than 

 what has heretofore taken place, would be of infinite use to 

 meteorological science, by inducing gentlemen more par- 

 ticularly to exert themselves to keep regular journals of the 

 pressure and temperature of the atmosphere ; thereby ob- 

 taining, in the course of a series of years, a more perfect 

 average kuowhi] ye, by which to judge of the changes that 

 are to take place in the weather. 



I beg to say, that I have His Grace the Duke of Gordon's 

 sanction for sending his Table. 



I reiTiain, sir. 

 Your most obedient humble servant, 



Twickenham, April 1 7, 1812. GrAY.
