neither the Nitre with the Oy/, nor the Oy! with the Spirit, nor the 
Nitre wich the Spirit, will make the leatt Ebullition: yetall three mingled 
together, make a very confpienaus one. The Spirit of Wine being asihe 
Sulphur 5 and fo that, and the Nitre together, (kanding,as it were, in the 
ftead of an Alkalizate, that is, a Suphurions Salt, againk the Oji of 
Vitriol.  Diversother Experiments may be (hew'n of the like Nature. 
7: $. Yo the laft place, for the Imitation of a Mineral Body, Twill 
inftance in two, fè, Nitre and Marine Salt if Imay have leave to reckon 
them among Mineral Bodies... As for Nire, by mixing of four Lie 
quors together, and then fetting them to fhoat 5 I have obtained Chry- 
als of true and perfect salt; which have had much Of a nitrom taft; 
and would be melted with a gentle Heat, as Nitre iss and even as ealily 
as Butyr it felf; 1 mean not, by the addition of any fort of Liquor, 
or any other Body, to diffolwe it; but only by the frre. 
8. $. Andasfora Sea-salt, that I might Imitate Nature for the ma- 12 
king thereof, I confiderd, That the (aid Salt is nothing elfe 
but that of Animals; and Vegetables, freed from its true Spirit and Sul- pio 
phur, andfome Saline particles, fpecifically Animal or Vegetable, together of 
with them. For both Avimal and Vegetable Bodies bein 
ig continually 5 as 
carried by all Rivers into the Seas and many likewife by Shipwrack y “athe 
and divers other waysimmerfed therein: they are at laft corrupted, that 
is, their Compounding parts are opened and refolved. Yet the Refolu- 
tion being inthe Water, is not made precipitately „ as it isin the Air 5 
but by degrees, and. very geztly 5, whence the Sulphnrions and other 
Volatile parts, in their Avolation, make not ‘fo much hafte, as to care 
ry themore fixed Saline parts along with them ; but leaveth them be- 
hind in the Water, which izebibeth them as their proper Menftruum. 
And the Imitation of Nature herein, may be performed thus 5 Put 
asmuch of aLixivial Salt as you pleale, into a wide-mouth’d Bottle, 
and with fair Water makea {trong Solution of it 5 fo as fome part there- 
of may remain w#refolved at. the bottom of the Bottle, Let the Bot- 
tle ftand thus for the fpace of about half or three quarters of a year, all 
the time unftopped. In which time, many of the Sulphurions and other 
Volatile parts gradually flying away 5, the. top of the smmrefolued 
Salt will be ¿ncruffate, or as it were frofied over, with many fmall and 
hard Coxcretions, which, in their nature, are become a true Sea-Salt, 
Whereof there is a double Proof; Firf, In that moft of the faid Con- 
erections are of aCubical, or very like Figure, Efpecially on their upper 
+ parts; becaufe having a fixed Body for their Bafis, their under parts, 
therefore, contiguousthereto, are lef regular. Whereas the parts of 
the Salt inthe Sea, being environed on all fides with a Fluid their Fi- 
gure is on all fides regular. Secondly, In. that: a {trong Acid Spirit or 
Oyl being poured upon a full body d. Solution hereof; yet it maketh Y 
herewith no Ebullition, which is alfo the property of Sea-Salt. And A 
thus much for the more General Imitation of Bodies. Ry
