A new physical system of astronomy : an attempt to explain the operations of the powers which impel the planets and comets to perform eliptical revolutions round the sun, and revolve on their own axis : in which, the physical system of Sir Isaac Newton, is examined, and presumed to be refuted ; to which is annexed, a physiological treatise ; in which the first stage of animation is considered, and the means shewn, by which circulation is performed in the first rudiments of the incipient animal, before the vessels are completely organized, &c. ; together with an explanation of the general laws, by which the animal economy is governed ; and particularly, the mode whereby the operations of the vis medicatrix naturae, or the unassisted powers of nature, are exerted to obviate and cure disease ; also, successful methods of curing cancerous ulcers, the quartan ague, putrid fevers, stopping mortifications, and extracting frost, so as to leave the frozen member perfectly well / by Joseph Young, M.D. of New-York.

    when there should happen what is called a spring tide, a little after the moon has passed the meridian, and he will find the water flowing up the river to- wards Albany : it is demonstrable, that the waters are propelled to the northward and southward, by a repulsive influence of the sun and moon ; and that when they have passed, and cease to repel, the water flows back towards the equator, until it is repelled again by the same power. So far we have proceeded tolerably well; but the most difficult question remains yet to be answered, to wit :—What causes the tides on the opposite side of the earth to correspond so exactly with those on this side? This must be explained, and that without hoops too ! otherwise, our whole fabric falls to the ground. Let us then say, that the most dense and weighty part of the earth's atmosphere, is always in a point opposite to the centre of the repelling body, whether it be the sun or moon, or both acting in conjunc- tion ; therefore the pressure is greatest on that part of the ocean, where the apex of the atmospherical cone is vertical, which produces the same effect on that side of the globe, by appulsion, as is produced on the other side by repulsion ; and this will continue to be the case, as long as action and re-action con- tinue to be equal. By this means high tides are pro- duced to the northward and southward, and little or none at the equator; at which place they should be most considerable, agreeable to the Newtonian hy- pothesis of attraction.
