and $ths. Sal Gemme, 6 Inches, and ¿ts Common Salt, 6 Inches and 
ats Salt of Tartar, not above 4 Inches and} All which differe 
cesare plain, and molt of them very remarquable: Two Ounces of sal 
Armoniac raifiog the Water near four times as high, as the fame quan« 
tity of Salt of Tartar, 
7- $. From this and the fourth Experiment, compared, it alfo aps 
pears, That the feveral {paces gained by the feveral Salts, though fome- 
times they do, yet do not always anfwer to the Solubility of the faid 
Salts. As to give fome Inftanecs ; Loaf-Sugar is the molt difloluble of 
any other Salt; ‘yet it gaineth lef {pace than all the reft, fave only 
Sal Armoniac. So Green Vitriol is more diffoluble then either Nitre 
or Common Salts yet gaineth lefs fpace than either, efpecially than the 
latter. And sal Armoniac, which is more diffoluble than Alum or Bo- 
7 rax, yet gaincth lef fpace than either of them. The Canfe whereof 
dere is not eafily affigned. 
dol 8. $: Notealfo, that by the fame Experiment, as well as by the 
"LU Tafle and other Circumftances, it is plain, That $a! Germe is nothing 
Win elle but Common Salt, coagulated or Cryflalliz’d under Ground, 
gapio 9- $. Again, as the Fifth Experiment fheweth, That there are 
pe man Vacnities in Water : fò doth this Laft, that thofe Vacnities, are of differ- 
ehe ing kinds. Becaufe, otherwife, it fhould feem, That the Bulk of the 
Ip) Water would increafe,morc or leß,according to the Solubilitie of every 
, pained Salt, and not be alternately differenced as it is; Some Salts, more 
5 below difloluble, increafing the Bulk of the Water lef, and othersleß difio- 
luble, increafing it more. I fay, that this difference dependeth not 
sches. only upon the different Figures of the Atomes of Salt 5 becaufe then 
kigus, every Salt which is more difloluble, would (quantity for quantity ) 
ves then take up lef room in the Water : which is contrary to the Experiment. 
wich ano- Io. $. From the fame Experiment, howfoever paradoxical it may 
fds of  feem, yet is it alfo manifeft, That although Water bea Fluid, yet the 
sgil Particles thereof are hard and confifent, and unalterable in their Figure. 
y ginei Otherwife it is plain, That all manner of salts would be diffolved in 
the fame manner, and take up the fame room in the Water. For let 
the Figures of the Salts be never fo various, yet ifthe Particles of 
Water were themfelves Fluid or Inconfiftent and Alterable, they would 
always fo conforme to thofe Figures asto fill up all Vacnities 5 and lo 
upon the Solution of feveral Salts, if of equal quantity, the Water 
would (till retein an equal Bulk. As fuppofe an Ounce of Iron were 
drawn into Wyer, another beaten into Plates, a third made into Hooks, 
a fourth into Needles, a fifth into Nails; every one of thee five Oun- 
ces, being put feverally into Water will encreafe its Bulk equally. I 
conclude therefore, That the Atomes of Water are hard and unalter- 
able. 
11. $. The Eighth Enquiry was this, What that jnft {pace 
might be, which any Salt gaineth upon Difolutiou, with reipe&t to its 
own Bulk, or the Bulk of the Water? For the making of this Experi- 
ment, Water will not ferve, nor yet Spirit of Wine; becaufe they both 
of them diflolve more or lef ofthofe Salts which are put into them 5 
whereby the obfe ion of the true Bulk of the Salt, and confequently 
of the juft. {pace it gaineth by Diffolution is loft. _ { took therefore Oyl 
of Turpentine, and pouring it into a Bolt. , marked the place of 
its afcent in the Neck, Then pouring likewife into it two Ounces of 
Common
