The [[underline]] VIS INETIÆ [[/underline]] of matter is only a consequence of [[underline]] Gravity [[/underline]]; for if any motion be given to a body it is only destroying the action of Gravity upon it; as a stone drawn along the ground overcomes the action or gravity that pins it to the ground, and alwa [[insertion]] y [[/insertion]] s endeavours to keep the body in the present state.  The [[underline]] vis inertiæ [[/underline]] of matter cannot be different from [[underline]] gravity [[/underline]], because it conspires with all its Laws; if it were different, then by giving a body motion the [[underline]] vis inertiæ [[/underline]] will act different [[strikethrough]] fro [[/strikethrough]] and in different directions, at sometime, from that of Gravity, and so there cannot be less than three forces in all moving bodies. W.J.

There is no [[underline]] resistance [[/underline]] of the air in the motion of a wind-mill; a ship under sail meets with no resistance from the wind; because the wind is the cause of both these motions; and a Cork put into a stream of water, running swiftly down a channel, will be carried a long without meeting with any resistance from the water, because the water is the cause of its motion (and a fluid both to give & resist ^ [[insertion]] the [[/insertion]] motion of the same body at the same time is an absurdity) in this manner the fluid of Light imping upon a pendulum in motion tends to pin or keep it to the middle of the arch of vibration, or perpendicular to the earth's surface; because the rays of light (the cause of gravity) issue from the sun & strike the earth perpendicular to its surface in every part: Therefore this medium or fluid is the cause of the pendulum's continuing in motion, so cannot resist it at the same time (as above) tho' in two different editions of the [[underline]] Principia [[/underline]] of S. [[superscript]] r [[/superscript]] I. [[underline]] Newton [[/underline]], He adopts this for his subtle fluid, first, to give no resistance to bodies in motion, but in another edition the very same experiment is brought to shew that it does resist motion and so it remains with all the Newtonians to this day. W.J.
There may be an inequality of pressure upon bodies in an exhausted receiver, because, from the prismatic Colours, it is evident light is in different conditions, and that the [[underline]] red [[/underline]] making rays are constituted of the very smallest particles, & those of the [[underline]] violet [[/underline]] of the very largest, and particular bodies will receive only one particular sort of rays, and that of the finer sort (exclusive of those bodies that are transparent, which admit all the rays, so will be of the same colour as before passing the body) and those of the coarser press upon the surface with a much greater force than the Air can do.  W.J.
The ingenious and great D. [[superscript]] r [[/superscript]] [[underline]] Boerhaave [[/underline]] in making [[underline]] oleum tartar per deliquium [[/underline]] found the dry mixed salt, in open air, to spontaneously dissolve by water, and encrease much in weight, even to three times the original weight of salt imploy'd, and to obtain this water seperate, he distilled the [[underline]] oleum tartari per deliquium [[/underline]] to dryness. then remarks that this water performs the solution in a different manner from common water, because being
