70 Fall, in the Proportion of the Squares of Distance from the Center; so that a Tun at the Surface of the Earth would weigh but ¼ of a Tun, removed one Semi-Diameter of the Earth higher; and at three Semi-Diameters, but the $1/16$ of a Tun. In like manner their Velocities of Descent decrease: A Body at the Surface which would fall 16 foot in a Second, at 12000 Miles high, or three Semi Diameters, would fall only $1/16$, or one Foot in a Second; but at all given Distances, something, &c.

Now, according to this Rule, heaving a Lead in great depths of Water, the Velocity should increase with the descent or sinking of it; since in the Progress of Gravity, the falling Body in every space of Time receives a new Impulse, and continually acting, the same Gravity super-adds a new Velocity; so that at the end of two Seconds, to be double what it was at the end of the first, and so on, which here the Weight of the super-incumbent Medium should still more accelerate. Yet a Lead-line is drawn out perceptibly slower at the second,than the first hundred Fathoms; But perhaps this proceeds from the increasing quantity of Line to be drawn with it, not so equally apt to demerge. and a Nisus in all Bodies of Water, from below upwards, contrary to Gravity.

4. The Winds were more Southerly than above, checking the Land-Breeze, which
