“ It not being our Authors present Task, to deliver a Body of Hydrostaticks, but only some Paradoxes, which he conceives to be proveable by his New way of making them out, he delivers them in as many distinct Propositions ”

“ Where he intimates, that though Fishes have not true Lungs, yet they want not a Succedaneum thereto; to wit, the Gills and if water may be to Fishes, what Air is to terrestrial Animals, for Respiration: asserting, that whereas nothing is so necessary for the conservation of Animal life as a reciprocal Access and Recess of the Ambient to the sanguineous vessels, tis all one, whether that be done by receiving the Ambient within the body, or by its gentle passing by the Prominent vessels of the Gills. ”

“ Which latter I the rather add, because I have sometimes observed in Sunshiny weather, when there have come Clouds for some considerable time (suppose an hour or two) the Quicksilver has fallen; and then, upon the Suns breaking out again, it has risen as before.
In Rainy weather, it useth to fall (of which the reason is obvious, because the Air is lightned, by so much as falls:) In Snowy weather, likewise, but not so much as in Rain. And sometimes I have observed it, upon a Hoar-frost, falling in the night. ”

“ Those others are often changed by Dews, which do not at all alter the Ballance, nor alter the state of the weather: And the open Weather-glass is known to signifie nothing at certainty, having a double obedience to two Masters, sometimes to the Weight of the Air, sometimes to Heat, as the service is commanded. ”

“ He hath also considered it in relation to an unmovable point, which he has supposed to be the first point of Aries, because we thither refer here upon Earth the beginning of all the Celestial motions, and there is the Primum mobile, that one would imagine, if we were in Jupiter, as we do here imagine Ours of 24. hours.
The Discovery is one of the best, that have been yet made in the Heavens; and those, that hold the Motion of the earth, find in it a full Analogy. ”

“ Whence he inclines to infer, that, since every fœtus; takes in at the mouth the liquor it swims in, and since the Chicken receives the white of the Egge into the mouth, and the yolk by the new discover'd ductus into the Intestins, it cannot be certainly made out, that a part of the Chyle is conveyed into the Liver, before it passes into the Heart: Exhorting in the mean time the Patrons of the Liver, that they would produce Experiments to evince their Ratiocinations. ”

“ But, contrary to what would have been expected, it was at 9. of the Clock at night, higher by 3/8 of an inch, than it had been at 4. occasioned by the change of weather, the Frost suddenly breaking, with us, between 5. and 6. of the Clock; about which time also it began to rain, and continued raining that Evening and good part of the Night. And the next morning I found the Liquor yet higher by half an inch, vid. 151/4 inches: (by reason of the Air that night being so much warmer, than it had been the day before;) whereas commonly it is considerably lower in the morning, than over night. ”

“ Besides, that its motion differed from that of the Shadows, which is almost equal, as well towards the Edges as towards the Middle of Jupiter: Whereas, on the contrary, this Spot hath all the accidents, that must happen to a thing, which is upon the surface of a round Body moving; for example, to move much more slowly towards the Edges, than towards the Middle, and to pass over that part, which is in the middle of the Diske, equal to the half of the Diameter, in the sixth part of the time, it takes to make the whole revolution ”

“ Yet this I have often observed; that the Air by the Thermoscope has appeared considerably colder (and the liquor lower) at sometimes when there is no Frost, than at some other times, when the Frost hath been considerably hard.
In my Baroscope, I have never found the QUicksilver higher than 30. inches, nor lower than 28. (at least, scarce discernably, not 1/16 of an inch higher than that, or lower than this:) which I mention, not only to shew the limits, within which I have observed mine to keep, vid. full 2 inches, but likewise as an Estimate of the Clearness of the Quicksilver from Air. ”

“ That a Body, immersed in a Fluid, sustains a Lateral pressure from the Fluid; and that increased, as the depth of the immersed Body, beneath the Surface of the Fluid, increaseth.
8. That Water may be made as well to depress a Body lighter than it self, as to buoy it up. ”

“ The lowest descent of the Mercury in all the time, since I have observed it, was Octob. 26. 1665. in the Evening, when it was very near at 271/2 Inches. Which I find thus circumstanced with the weather in my notes.
Inch.
Oct. 25. Morning; Mercury at 281/2. Great storms and much rain.
Oct. 26. Morning; Merc. at 28. winds quiet, thick dark clouds.
Oct. 26. Evening; Merc. at 271/4. That day, and some daies following, the weather was variable, frequent rain, and as you see, the Mercury lower, than usual. ”

“ Besides, that the Hydrostaticks may be made divers waies serviceable to Chymists, as the Author intimates, and intends to make manifest, upon several occasions, in his yet unpublisht part of the Usefulness of Natural and Experimental Philosophy. ”

“ And the like account I have had from some others in Oxford, who yet did not think of an Earth quake; it being a rare thing with us. Hearing afterwards of an Earthquake observed by others; I looked on my Notes concerning my Thermoscope and Baroscope, to see if any alteration considerable had then happened.
My Thermoscope consists of a round large Glass, containing about half a pint or more; from whence issues along Cylindrical neck of Glass, about two foot and a half in length, and less than a quarter of an inch diameter ”
