Influence of the Moons Declination 



[May, 



gistered at Calcutta, there are (6) six instances in which the barometer has 

 fallen below the height of 29-200 inches. — I here add the dates of each instance, 

 with the heights of barometer and declination of moon three days before, and three 

 days after; also the day of nearest new or full moon. The hour of 4 p. m. has 

 been chosen, as corresponding better than any other to the hour of noon at Green- 

 wich, at which time the declination of the moon was taken.
