From the observations made on the 14th of May, that have 

 already appeared, it seems that the barometer was not so sta- 

 tionary on that day in some parts of the country, as it was here, 

 and at Manchester. According to the observations of Mr. Gary 

 in page 400, it appears to have been steady from nine o'clock 

 to one, at the place where they were taken ; but at Bushy-Heath, 

 and Northampton, its fluctuations were frequent, and consider- 

 able. 



It has not yet been ascertained, I believe, over what extent 

 of country it is usual for the variations of the barometer to be si- 

 milar on the same day; nor in what manner these variations are 

 influenced by the force and direction of the wind. 



To determine these two important points with a tolerable de- 

 gree of precision, would require a well arranged plan of observa- 

 tion, and the mutual co-operation of a number of individuals 

 stationed in different parts of the kingdom : and when it is con- 

 sidered what curious and interesting subjects of inquiry these are, 

 they will not be thought undeserving of the particular attention 

 of meteorologists. I am, sir, your obedient servant.

Sir, — I send you the Barometric Observations made at this 

 place, on the i4th of May, and 1 1th of June. The height of the 

 basin of the Barometer above the level of the sea, at low Water, 

 I estimate to be about G8 feet. Yours obediently.
