Some of these I broke in the open air, by snapping off a little of the small stem with my fingers, others by crushing it with a small pair of Plyers; which I had no sooner done,...

This is a Creature so officious, that ’twill be known to every one at one time or other, so busie, and so impudent, that it will be intruding it self in every ones company, and...

And this seems to be the reason, why _Aqua fortis_, and other _saline_ liquors, if they come to touch the sensitive parts, as in a cut of the skin, or the like, do so violently...

As for the make and contexture of the Down it self, it is indeed very rare and admirable, and such as I can hardly believe, that the like is to be discover’d in any other body i...

There is indeed in _Piso_, a very odd History, which this relation may make the more probable; and that is in the 2. Chapter of the 4. Book of his Natural History of _Brasil_, w...

I procur’d me a small Pedestal, such as is describ’d in the fifth Figure of the first _Scheme_ on the small Pillar AB, of which were two movable Armes CD, which by means of the...

One of these Gnats I have suffer’d to pierce the skin of my hand, with its _proboscis_, and thence to draw out as much blood as to fill its belly as full as it could hold, makin...

A Fourth Argument may be drawn from this Experiment; Take a Glass-pipe, and fit into a solid stick of Glass, so as it will but just be moved in it. Then by degrees heat them whi...

But I found the proportion of Brine to fresh Water to be near 13 to 12: Supposing therefore GHM to represent the Sea, and FI the height of the Mountain above the Superficies of...

I took the creature, I had design’d to delineate, and put it into a drop of very well rectified spirit of Wine, this I found would presently dispatch, as it were, the Animal, an...

In all which I observ’d, that if they were of any regular Figures, they were always branched out with six principal branches, all of equal length, shape and make, from the cente...

In the fifth place, that the droppings or trillings of Lapidescent waters in Vaults under ground, seem to constitute a kind of _petrify’d_ body, form’d almost like some kind of...

I have little more to add of the Teeth of a Snail, besides the Picture of it, which is represented in the first _Figure_ of the 25. _Scheme_, save that his bended body, ABCDEF,...

It is evident therefore by this _Hypothesis_, that at the same time that ef touches f. EF is arrived at c. And by that time efkn is got to n, EFKN is got to d and when it touche...

I have never seen nor been enform’d of the true manner of the growing of Sponges on the Rock; whether they are found to increase from little to great, like Vegetables, that is,...

Whil’st I was examining and considering the curious _Mechanism_ of the wings, I observ’d that under the wings of most kind of Flies, Bees, &c. there were plac’d certain _pendulu...

And the first I shall propound is, Whether there may not be made an artificial transparent body of an exact Globular Figure that shall so inflect or refract all the Rays, that,...

Next, it seem’d nothing more difficult to give an intelligible reason, why Cork is a body so very unapt to suck and drink in Water, and consequently preserves it self, floating...

But to proceed; I observ’d several kind of hairs that had been Dyed, and found them to be a kind of horny _Cylinder_, being of much about the transparency of a pretty cleer piec...

Next we learn, that the great reason why _pellucid_ bodies beaten small are white, is from the multitude of reflections, not from the particles of the body, but from the _contig...

The lower end of this wreath’d Cylinder being stuck upright in a little soft Wax, so that the bended part or _Index_ of it lay _horizontal_, I have observ’d it always with moist...

But there is one Instance more, which was first shewn to the _Royal Society_ by Mr. _Clayton_ a worthy Member thereof, which does make this Assertion more evident then all the r...

Now, if these Cods have a seed in them so proportion’d to the Cod, as thole of _Pinks_, and _Carnations_, and _Columbines_, and the like, how unimaginably small must each of tho...

From which Experiments, I think, we may safely conclude, that the Elater of the Air is reciprocal to its extension, or at least very neer. So that to apply it to our present pur...

And secondly, as to the other of these operations on colours, that is, the deepning of them, Limners and Painters colours are for the most part also uncapable. For they being fo...

Suppose we therefore AB in the eighth _Figure_ of the sixth _Scheme_, to represent a tinging _Globule_ or particle which has a greater refraction than the liquor in which it is...

Moscovy-glass, or _Lapis specularis_, is a Body that seems to have as many Curiosities in its Fabrick as any common Mineral I have met with: for first, It is transparent to a gr...

Having, in the last Observation, premis’d some particulars observable in the _medium_, through which we must look upon _Cœlestial_ Objects, I shall here add one Observation of t...

And therefore, what ever is by some, who have written of it, and particularly by _Francisco Stelluto_, wrote a Treatise in _Italian_ of that Subject, which was Printed at _Rome_...

In which Experiment, there are three Observables that seem very manifestly to prove the porousness of these seemingly close bodies: the first is their acquiring a transparency,...

Nor are the other three so perfect, but that _diligence_, _attention_, and many _mechanical contrivances_, may also highly improve them. For since the sense of _smelling_ seems...

Or further in the _third figure_, let AILD represent an including _solid_ medium of a cylindrical shape (as suppose a small _Glass Jar_) Let FGEMM represent a contain’d _fluid_,...

And this was undertaken in prosecution of the Design which the _ROYAL SOCIETY_ has propos’d to it self. For the Members of the Assembly having before their eys so many _fatal_ I...

These threads that compose this fine contexture, though they are as small as those that constitute the finer sorts of Silks, have notwithstanding nothing of their glossie, pleas...

I have further taken notice, that not onely the Sun, Moon and Starrs, and high tops of mountains have suffer’d these kinds of refraction, but Trees, and several bright Objects o...

_The texture of _Muscovy_ Glass; its Figures: what other Bodies are like it: that it exhibits several colours, and how: several Observations and Experiments about those colours:...

And that we may the better finde what the _cause_ of _Congruity_ and _Incongruity_ in bodies is, it will be requisite to consider, First, what is the _cause_ of _fluidness_; And...
