Not indexed.

This ratio represents the proportionate elevation or depression of the barometer above or below its mean height, that should be caused by the earths rotation, and it corresponds very nearly with the actual disturbance at stations near the equator. From Oh. to 6h. the air has a forward motion greater than that of the earth, so that it tends to fly away; its pressure is therefore diminished, and the mercury falls. From 6h. to 12h. the earths motion is greatest; it therefore presses against the lagging air, and the barometer rises. From 12h. to 18h. the earth moves away from the air, and the barometer falls; while from 18h. to 24h. the increasing velocity of the air urges it against the earth, and the barometer rises. If the force of rotation at each instant be resolved into two components, one in the direction of the radius vector, and the other parallel to the earths orbit, it will be readily perceived that whenever the latter tends to increase the aerial pressure, the former tends to diminish it, and vice versa. Let B the height of the barometer at any given instant; Mthe mean height at the place of observation; 0--90 the hour angle; c the earths circumference at the equator;--24 hours; g the terrestrial gravity; J the latitude; and a simple integration gives the theoretical formula, r sin. 0. cos. 8. cos. I 2c---m(i----jy This formula gives a maximum height at 9h. and 21h. , and a minimum at 3h. and 15h. The St. Helena observations place the maximum at lOh. and 22h. , and the minimum at 4h. and Kill. , an hour later in each instance than the theoretical time. This is the precise. . .
