Abstracts of the Makerstoun Observations, 1843. 
Atmospheric Pressure with reference to the Moons Age. — From the means in the Table, and the following 
means of groups, it is distinctly evident that a maximum of pressure occurs about two days after full Moon, 
and a minimum of pressure about two days after new Moon ; the same result has been obtained, Table X., for 
that portion of the atmospheric pressure due to the aqueous vapour.

Atmospheric Pressure with reference to the Moon's Declination. — The means in the previous Table, and in 
the following means of groups, indicate two maxima and two minima. The principal maximum occurs about 
two days before the Moon is on the equator moving northwards ; the two minima are nearly equal, the one 
occurring when the Moon is farthest north, the other about two days before it is farthest south ; the secondary 
maximum occurs about one day before the Moon is on the equator moving southwards.
