“ The Osteocolla being thus found, is altogether soft, yet rather friable than ductil: Wherefore if one hath the curiosity of getting out of the ground a whole piece of it with its branches, he mutt very carefully remove the Sand every way from it, and then let it lie so a while; its quality being, That remaining exposed to the Sun for half an hour or somewhat longer, it growes to that hardness, as 'tis found in the shops of Apothecaries. ”

“ The Groove is supported by Timber of a Divers bigness, as the place gives leave. A piece of an Armes bigness will support 10 tun of Earth. It lasts long; that which was put in beyond the memory of man (nay, which by the difference in the manner of working their mines, they know to have layn above 200. years) will serve in new VVorks. It is tough and black, and being expos'd to the Sun and Wind for 2 or 3 dayes, will scarce yield to an Axe. That which hath layn 40 yeares to their own knowledge, they have taken up, and set again. ”

“ Eight ounces being put in, after a little while there were seen to rise by little and little out of the Mercury a thousand small Silver-like branches or threds, spreading themselves every where through the whole Liquor, and shooting up even above the surface of the Water, on which appear'd here and there an oleosity, that was taken off, as being some matter of a grosse excrementitious nature, and heterogeneous to the substance it self of the Mercury, hindring the coagulation of the Mercury, but being remov'd, the Mercury runs and sticks close together, and becomes a firm Mettall. ”

“ That in salt, how -much soever depurated, there will be found a true Earth, which though seemingly destitute of all salt, yet being for some dayes exposed to a clear sky and the Sun, will be again impregnated with new salt. To which he declares, that if Kircher had continued his method of purging salt to the utmost, he would have found, that the whole body of salt would have been at last thus changed into a saltless Earth, altogether inefficacious, save a little adstringency ”

“ Painting and Sculpture are the politest and noblest of Antient Arts, true, ingenuous, and claiming the Resemblance of Life, the Emulation of all Beauties, the fairest Records of all Appearances whether Celestial or Sublunary, whether Angelical, Divine or Humane. ”

“ Take one drachme of crude Antimony powder'd for one Horse, and when you give him his Oats in a morning, shake it out upon his Oats in a little heap in the middle: If he be hungry, and you keep off his head from every other part of the Oats, he will snap it up in his mouth at one bite, when you let him goe. ”

“ A black Stone is of bad signification, and leads to a Jam (a black thick Stone, that hinders their work.) A grey cleer dry one they account best. They seldome encounter Damps. If in linking they come to wet moorish Earth, they exspect a Jam, and to be closed up with Rocks. ”

“ There is a flight in the smoak, which falling upon the Grass, poysons those Cattel that eat of it. They find the taste of it upon their lips to be sweet, when the smoak chances to fly in their Faces. Brought home, and laid in their houses, it kills Rats and Mice. ”

“ The branches are not of an equal thickness, but, like plants growing above ground, some of them thicker, some slenderer; and the farther they are distant from the common stem, the thinner they are, the stalk being thickest of all, usually equalling the thickness of an ordinary Arm or Legg, and the branches, the thickness of on's little linger. ”

“ They cut a Trench, at a little distance from the top of the Groove, covering it with Turf and Rodds disposed to receive into the pipe, which they contrive to come in, sidewayes, to their Groove, 4 foot from the top; which carries down the Air to a great depth. When they come at Ore, and need an Air-shaft, they sink it 4 or 5 fathom distant, according to the convenience of the breadth, and of the same fashion with the Groove, to draw as well Ore as Air. ”

“ Beetles, Axe, Wedge, unless so hardned as to make a deep Impression upon the head of an Anvill, are not Ht for their use; and yet they sometimes break them in an hour; others last 3 or 4 dayes, as it happens. ”

“ He examins also, whether common Salt may be changed into Vitriol, Alum, Niter. Some (among whom is Kircher) esteeming that the common Salt, according as 'tis variously tinged by Minerals, is sometimes converted into Niter, sometimes into Alum, sometimes into Vitriol, and yet may be reduced into common Salt again. But our Author finds not this in Laboratory's, but that Niter by a flaming fire degenerateth into an acid liquor; being burnt by coals, into a Lixiviat Salt highly different from the nature of Common Salt ”

“ And it often happens, that that stroke loseth it self by little and little, and the Osteocolla in the middle grows clear; which comes to passe, when the Root by the corruption, begun in the Osteocolla, is reduced to powder. Yet have I found a place hereabout, where the Osteocolla was not hollow at all ”

“ They work cloath'd in Frocks and Wait-coats, by Candle-light of Tallow; 14 or 15 to the pound, each whereof lasts 3 houres, if they have Air enough: which if they want to keep in the Candle, the Work-men cannot stay there. A Vein-being lost, they drive 2 or 3 fathom in the breast, as the nature of the Earth directs them. ”

“ This he illustrates by that substance, call'd Cornu Lunæ, which is nothing else, but Silver, whose texture is changed by the particles of acid Spirits, which is fusible at a Candle, and sequacious, and may be reduced into small leaves, transparent, and somewhat obedient to the Hammer. Farther, having taken notice that Glass is a very brittle body, because the surfaces, according to which its particles touch one another, are exceeding small ”

“ The Ore tends to the bottom, and the Refuse lies at top. And these are the Preparations, they make use of, before 'tis fit for fusion. Then they have a Hearth about 5 foot high, set upon Timber, to be turn'd as a Wind-mill, to avoid the inconvenience of smoak upon a shifting VVind. ”

“ Another Observation is of a Ductil Salt, said to have been made by himself of Sal Armoniack, often dissolved in a large Glass, and frequently and slowly Chrystallised, whence at length proceeded Chrystals as long as the Vessel was large; some of them being at times 6 inches long, flexible, and apt to be restored again into a streight line ”

“ If they rind a Swallet, they drive an Adit upon Levell, till 'tis dry. Seldome Damps.
To the 41, 42. I referr to a Melius inquirendeum: Only they find no prejudice from any Iron-ore.
To the 43, 44. If they cannot cut the Rock, they use Fire to aneale it, laying on Wood and Coale, and the Fire so contriv'd, that they leave-the Mine before the Operation begins, and find it dangerous to enter again, before it be quite clear'd of the Smoak; which hath killed some. ”

“ The 15th, 16th, 17th, and 18th give the measuring of a Sphere, Spheroid, Parabolick Conoid and Hyperbolick Conoid, as well the whole as their parts.
The 20th measureth Circular and Elliptick Spindles.
The 21. measureth the 2d Section in a Sphere and Spheroid, which may be of use to measure the midle Zone of a Spheroid, cut by a Plane parallel to the axis; i.e. when the superfice of the liquor cuts the head of the Cask. ”

“ Yet this he grants to Kircher, that common Salt will turn into Niter, Alum, and Vitriol, when it hath changed its particles by the motion of subterraneous Fires, and so being comminuted into small particles hath converted its former Salt-taste into a present acid one, yet so as that for the composition of Niter there must be mixt some ramenta of Lixiviat Salt ”

“ Sed & duo puncta duobus punctis, tria momenta tribus momentis, decem spiritus decem spiritibus; numero æquales esse possunt; utut non habeant, secundum quam comparentur, corporis molem. Requiritur utique ad Æqualitatem atque Inæqualitatem, non quidem sola quantitatum comparatio; verum etiam ut quantitates comparatæ sint Homogeneæ; (quod ex Euclide modo diximus;) ut juæta corporis molem amplitudinemve comparentur, non requiritur: ob causas modo dictas.
Neque tam ego ipsi hac in re contradico, quàm ipse sibi. Quippe (tanquam dictorum sect. 13. oblitus,) subjungit sect. 14. ”

“ Verum hoc non ille primus docuit, sed Euclides olim; (ut modo dictum est;) atque post illum alii, nedum qui illo suerunt superiores. (Quamquam hoc ipsum à Dulaurensio vix tuto dicitur; ut qui Æqualitatem atque Inæqualitate non in ipsa Qunatitatum Homogeneorum natura fundatem esse vult, sed in rerum Distinctione; adeoque Heterogeneis, utpote non minus inter se distinctis pariter convenire debent, atque Homogeneis:) Id autem requiritur, ut quoad saltem illud mensuræ genus, quo comparantur, sint homogeneæe; ut autm illud sit moles corporea, non requiritur. ”
