424 Dr BARNES'S Remarks on, and Tabular Results of, 



nals and the Tables be found useful in promoting the advance- 

 ment of the science of Meteorology, I shall feel highly gratified, 

 by having contributed my mite to so desirable an object. 



It is not improbable that these meteorological journals might 

 be made useful and valuable, by comparing them with similar 

 journals kept at the same time by other observers, at different 

 and distant places. They would shew the agreement and diffe- 

 rence of atmospheric phenomena in different regions of the 

 earth ; and perhaps important conclusions may be drawn from 

 their comparison. As I have had few opportunities of examining 

 journals of this kind, I shall not offer any opinion respecting 

 them, neither shall I at present attempt to draw any conclusions 

 from the comparisons I have made. I shall merely observe, that 

 I have met with some instances of remarkable simultaneous fluc- 

 tuations of the barometer, occurring in places at a considerable 

 distance from one another. Among them, the following may be 

 mentioned. On the 30th of November 1816, the barometer at 

 Carlisle stood uncommonly high. According to the register, it 

 was as high as 30,77, morning ; 30,77, afternoon ; and 30,80, 

 night, wind north-west. On the same day, at Edinburgh, there 

 was the greatest elevation of the barometer that had been ob- 

 served for several years. The mercury, 135 feet above the level 

 of the sea, stood at 30,640 in the morning, and 30,602 in the 

 evening, wind west *. On the night of the 4th of March 1818, 

 the barometer at Carlisle was unusually low. It was as low as 

 28,24 ; the following morning 28,43 ; in the afternoon 28,60 ; and 

 at night, 28,81, wind south-west. The weather had been very 

 stormy, with violent hurricanes, and heavy showers of hail and 

 snow for several days. A hurricane occurred during that night. 

 At Edinburgh, there was similar weather, with hurricanes ; and 

 on the 5th of March, at 8 o'clock of the morning, the barometer
