actly one inch in that time. Thinking it might have been a 

 typographical error, I was induced to add up and find the 

 mean of the month's pressure at Boston, but found that 29-75 

 inches in the morning of the 12th of October had been added 

 to make up the mean pressure 29-43 for the month. — If the 

 pressure that morning was only 28-75 inches, as I have rea- 

 son to suspect it was from the quiescence of the barometers, 

 in that case the mean for the period is 29-40 inches. — I merely 

 mention this circumstance for Mr. Veall's consideration, as I 

 intend to give the monthly and annual results of the tables ; 

 and if he admit it as an inadvertent error, an erratum to that 

 effect should either be made in your next Number, or at the 

 end of the volume*. 



In a close collation of the tables for this year, I also find 

 that Mr. Veall's barometer in the morning of the 24th of July, 

 was -63 of an inch lower than mine, that is nearly -4 of an 

 inch less than its comparative mean level. The weather then 

 being fine and very dry at both places, and for some days be- 

 fore and after, it would be difficult even to attempt to investi- 

 gate the cause of so great a difference in the pressure of the 

 atmosphere at the respective places, without the precise state 

 of the hygrometer and wind, which I can only get from my 

 own register. If Mr. Veall could conveniently register the 

 position of the wind when he takes the altitude of his baro- 

 meter, it would certainly tend to throw, some light upon the 

 subject of great deviations from the comparative mean pres- 

 sures at Gosport and Boston ; and it were much to be wished 

 that your London register gave the state of the barometer at 

 8, or half-past 8, A.M., instead of at 1, P.M. ; as one of the 

 chief objects of a monthly meteorological table in your valu- 

 able Magazine, is comparison, which will be materially obvi- 

 ated without simultaneous observations on the instruments at 

 the time proposed. 



I am, gentlemen, 



Your obedient servant, 

 Gosport, Nov. 25, 1824. William Burney.
