“ But though the light of Shining Fish be usually (as far as I have observed) more vigorous and durable, than that of Shining Wood; yet I cannot say, that it will hold out against Cold so well as the other: For having ordered one of my Servants to cut off a good large piece of the luminous Whiting, and bury it in Ice and Salt, when I call'd for it in less than half an hour after, I found it much stiffen'd by the Cold, and to have no light, that I could discern in a place dark enough. ”

“ The first difference I observed betwixt a Live Coal, and Shining Wood, is, That whereas the light of the former if readily extinguishable by Compression (as is obvious in the practice of suddenly extinguishing a piece of Coal by treading upon it) I could not find that such a Compression, so I could conveniently give, without losing sight of its operation, would put out, or much injure the light, even of small fragments of Shining Wood. ”

“ He hath spent 3 or 4 months without sleep, and his greatest divertisement during that time was, to tear the Clothes that were given him, to run naked abroad, and to burn in the Houses where he was whatever he could meet with. He mov'd to compassion all good people that saw him, and especially those in the Marais du Temple, where he was known to most, and where he had been wont to be seen before this distemper as well cloathed and fashioned, as any one of his condition could be. ”

“ For, though the beholder's Eye, that looks upon those Stars, be advantag'd by being in the dark, which enlarges the pupil of the Eye, yet the Object it self is freely exposed to the beams of the Sun, which if they were intercepted, those Planets would quickly be darken'd, as experience manifests in Eclipses. ”

“ So that if that spungy substance, which grows out of the edge of the Uvea, be so great, or the number of them such, as that they grow in several places about the pupil of the Eye, where it contracts it self, the pupil or sight is very much (if not totally) obstructed, and consequently the Horse sees very little or nothing at all: As I have many times taken exact notice in some Horses, which being brought into the Sun-shine, could not see at all but suffer'd me to touch the sight of their Eye with my finger without the least winking ”

“ And therefore inviteth those that are studious in that part of Philosophy, to consider, that our Body is an Engine made up of a thousand subordinate Engines, whose true knowledge whoever thinks that it can be investigated without Mathematical assistance, must also think, that there is matter without Extension, and Body without Figure. ”

“ For 'tis not to be doubted, but measures are to be taken to dispose the body for Transfusion, as well as for all other operations to be undertaken with success. But we need not repent for not having observed them in this case; it appeared much better what the Transfusion all alone could do, and no cause hath been given to prejudiced men to impute this cure to the Preparation, rather than to the Operation it self. ”

“ As a Quick Coal if not to be extinguisht by the coldness of the Air, when that is greater than ordinary; so neither is a piece of Shining Wood to be deprived of its light by the same quality of Air.
As much of this Observation as concerns the Coal, will be readily granted, and for proof of the other part of it, I could relate to you more Trials than one, but that I suppose, one may suffice, circumstanc'd like that, which I shall now relate. ”

“ A Square of Cells being given, even or odd, filled with Numbers, either in an Arithmetical or Geometrical Progression; so to dispose all those Numbers into another like square of Cells, that all the Numbers of each band, whether to the right or left, upwards or downwards, or diagonally, the Number given being in an Arithmetical Progression, added together, do always make the same Sum, and those in a Geometrical Progression, multiplied into one another, do always make the same Product. ”

“ Others, considering the pain in his Kidneys during the Transfusion and the swelling of his Stomach, which was presently follow'd by Evacuations above and below, do believe, that the new Blood entring in great quantity, caused a plenitude, and a fermentation in the great Vessels, which could not but be follow'd by all those effects. To which may be added, that almost all those, into whose Veins other Liquors than blood have been injected, have found the same Accidents. ”

“ Both of them are Luminaries, that is, give Light, as having it (if I may so speak) residing in them, and not like Looking-Glasses or white Bodies, which are conspicuous only by the incident beams of the Sun, or some other Luminous Body, which they reflect.
This is evident, because both Shining Wood and a Burning Coal shiner the more vividly, by how much the place wherein they are put is made the darker, by the careful exclusion of the adventitious light. 'Tis true, that the Moon and Venus appear brightest at or about Midnight, and yet have but a borrowed light ”

“ In the third (the Dioptricks, that consider Rays refracted) he treats largely of Telescopes of all sorts, Spherical, Elliptical, Hyperbolical' as also of Microscopes, and the effects of all of them: Where, among many other particulars, he delivers and commends, as an invention of Eustachio Divini, the way of furnishing a Telescope, with two Eye-Glasses, outwardly flat, and inwardly convex, so as that they touch one another in the center of their convex Superficies. ”

“ He subjoins a Letter to Monsieur Thevenot, in which, among other things, he alledges several Experiments, to shew, that the motion of the Heart is like the motion of Muscles; and answers those who pretend, that the true Fabrick of the Heart hath already been observed heretofore; and those likewise who think, that these new Observations of the Muscles are uncertain, concluding this Subject with an enumeration of the Particulars, yet remaining to be be search'd into in the History of the Muscles. ”

“ This Author pretends to have comprised in this Treatise, containing 58 Propositions, besides many Corollaries, all what hath been hitherto discover'd in Opticks, and to have added thereto many curious and useful remarks, not mentioned in other Authors.
He begins with that part which is the most simple, and considers the streight Ray, called by the general name of Opticks; where he shews, what is the cause of those surprizing effects of the Perspective, which so pleadingly deceive the eye; examining there many curious Experiments. ”

“ Some say, it proceeded from the disorder consequent to the entry of new blood into his Veins: Others have look'd upon it as the effect of a kind of Rhumatism he had got, lying stark naked in the streets; and have thought that he became not sensible of those pains, but after the recovery of his reason; just as those that have a hot Feaver do never complain of weariness, but after the abatement of the Fit.
There hath also been very differing discourse of that black colour in his Urine some days after the Transfusion ”

“ The former part of this, particular Tryals have often shewn you to be true, when kindled Coals, that seem to be extinguisht in our exhausted Receivers, were presently reviv'd when the Air was restored to them: And the latter part is abundantly manifest by the Experiments, to which this Paper is an Appendance.
4. Both a Quick Coal and Shining Wood will be easily quench'd by Water and many other Liquors. ”

“ Observations and Tryals about the Resemblances and Differences between a Burning Coal and Shining Wood. An Observation concerning a Blemish in an Horses Eye, not hitherto discover'd by any Author, which may be of a great use in the choice of Horses. An Extract of a Letter, written out of Italy, concerning divers Spots, not long since observed there in the Planet Venus. ”

“ But in pieces of Shining Fish I found the case much otherwise, as was to be expected.
6. The last Difference I shall take notice of betwixt the Bodies hitherto compared, if, That a Quick Coal is actually and vehemently hot; whereas I have not observed Shining Wood to be so much as sensibly lukewarm. ”

“ That wherein a Coal, as it burs, sends forth store of smoak or exhalations; Luminous Wood does not so.
5. A fifth, flowing from the former, is, That whereas a Coal in shining wasts it self at a great rate, Shining Wood does not.
These two unlikenesses I mention together, not only because of their affinity, but because what concerns the Coal in both, will need no proof; and as for what concerns Rotten Wood, it may be verified by an Observation, that I find by my Notes I made in a piece of it Hermetically sealed up in a small clear Glass ”
