and sth. Sal Gemma, 6 Inches, and sth» Common Salt, 6 Inches and 
ths. — Salt of Tartar, not above 4 Inches and $™ All which differens 
ces are plain, and moft of them very remarquable: Two Ounces of sat 
Armoniae raifing the Water near four times as high, as the fame quan- 
tity of Salt of Tartar. i 
7- §. From this and the fourth Experiment, compared, it alfo ap- 
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 Inftances; Loaf-Sugar is the moft difloluble of 
any other Salts yet it gaineth lefs {pace than all the reft, fave only 
Sal Armoniac. 80 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 Alnw or Bo- 
rax, yet gaineth lefs fpace than either of them. The Cane whereof 
is not eafily affigned. 
8. §. Note alfo, that by the fame Experiment, as well as by the 
Taffe and other Circumftances, it is plain, That sal Gewme is nothing 
elfe but Common Salt, coagulated or Cryftallizid under Ground, 
9. §. Again, as the Fifth Experiment fheweth, That there are 
Vacnities in Water : fo doth this Laft, that thofe Vacuities, are of differ- 
ing kinds. Becaufe, otherwife, it fhould feem, That the Bul of the 
Water would increafe,more or lefs,according to the Solubilitie ‘of every 
Salt, and not be alternately differenced as it is; Some Salts, more 
diffoluble, increafing the Bulk of the Water lef, and others lef diffo- 
luble, increafing it more. I fay, that this difference dependeth not 
only upon the different Figures of the Atomes of Salt , becaufe then 
every Salt which is more diffoluble, would (quantity for quantity ) 
take up lefs room in the Water : which is contrary to the Experiment. 
to. §. From the fame Experiment, howfoever paradoxical it may 
feem, yet is it alfo manifeft, That although Water bea Fluid, yet the 
Particles thereof are hard and confiftext, and unalterable in their Figure. 
Otherwife it is plain, That all manner of salts would be diffolved in 
the fame manner, and takeup the fame room in the Water. For let 
the Figures of the Salts be never fo various, yet ifthe Particles of 
Water were themfelves Flzid or Inconfiftent and Alierable, they would 
always fo conforme to thofe Figures,asto fill up all Vacuities 5 and fo 
upon the Solution of feveral Salts, if of equal quantity, the Water 
would ftill retein an equal Bu/, As fuppofe an Ounce of Iroz were 
drawn into Wyer, another beaten into Plates, a third made into Hooks, 
a fourth into Needles, a fifth into Nails; every one of thefe 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 Ezghth Enquiry was this, What that jnft {pace 
might be, which any Salt gaineth upon Diffolution, with refped 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 Wize, becaufe they both 
of them diffolve more or lefs of thofe Salts which are put into them 5 
whereby the obfervation ofthe true Bulk of the Salt, and confequently 
of the juft {pace it gaineth by Diffolution is loft. {took therefore Oy! 
of Turpentine, and pouring it into a Bolt-head, marked the place of 
its afcent inthe Neck. Then pouring likewife into it two Ounces of 
Common
