that luminary; also the greatest and least heights of the barometer on the same days, 
with the other circumstances relating to the moon, winds, and weather, in an interval 
of years from the common diary, we shall not be led to the conclusion, after a particular 
examination, that the moon has any material influence in the changes of the atmosphere 
here stated as shewn by the barometer: nor indeed shall we be able to conclude that 
her influence, like the sun’s, is at any time considerable, as regards the ordinary changes 
and motions of the atmosphere. While the moon raises the waters of the ocean, and 
gives light to the earth, we should be led to conclude from such experiments, that she 
exerts only a steady attractive power upon the air, and that her influence as relates to 
the changes often attributed to it, is not by any means so great as is commonly supposed. 
With respect to the changes shewn by the observations here noticed, they are effected 
by regularly-ordained causes for the purpose of rendering the atmosphere suitable for 
the purposes intended, and of course for the benefit of the noble creation it surrounds; 
it being essential that these changes should take place in the atmosphere regularly at or 
near the same times every twenty-four hours, while the times of the flux and reflux of 
the ocean are daily changing.
