Summary

Philosophical Transactions, Volume 3…

Why Comets are almost never perceiv'd' by Us, when they first emerge out of their Atmosphere? That, the motion of Comets hath a conformity with that of Ships. That the Sun does the same in the deviation of Comets, what a Pilot or Ship-master doth by the meanes of Cables in the direction of Sayling. That Comets, like Ships, describe sometimes an entire, sometimes a Semi-parabola.

That the matter and figure of a Comet, and the impetus at first impressed, make much to its motion: That Comets, which come out of larger Atmospheres, and from about their Equator, and are of a compact body, are swiftest, and especially those, that have their rise from the Sun, How the motion of the Spots of the Sun may be compared with that of Comets? How the greatest velocity and tardity of the motion of Comets may be limited? That there is a Libratory motion in Comets as well as in the Moon, &c.

THe Vessels, commonly called Lymphatick, have two Coates, betwixt which there are innumerable very small and very fine vessels like Filaments, resembling the Mosse of Trees, without any Valves, containing a nutritious Juyce convey'd into all the parts of the Body by a motion thereof from the center to the circumference; but returning through the inner pipes (furnisht with Valves,) of the same Water-vessels; at which time they are no more to be call'd Water or Dew, but Ferment, the vessels deferring also the name of Ferment-vessels.
