Scnm was grown thicker, after the fpace of 3 or 4 hours) 
and placing the fame before a Microfcope, I faw, that be* 
fides feveral fmall Particles, of which for the moft part 
the Scum was compos'd, there lay an unfpeakable Num- 
ber of Salt Particles, and thofe of very different figures, 
inforauch, that they are not to be defcribed : Some ot era 
were Long, Quadrangular and Hexangular Figures, ap- 
pearing all of era to be folid Cubical Bodies 5 tkeir longeft 
fidjes were parallel to one another 5 and when I view'd 
thefe Coagulated Salts, fome of which lay upon the Su- 
perficies of the Water, as others were funk to the bottom, 
I obferv'd that they were not only grown larger, but that 
each of em was encompafs'd with feveral Circles or Cir» 
cumferences. 
Moreover, where the Water was exhaled, there lay 
fuch an unfpeakable number of fmall Salt Particles, that 
they did in a manner efcape the fight, inforauch, that in 
fome of em it was impoflible to difcpver any figure ^ and 
of fome that were yet fmaller, there was nothing more to 
be feen in them than an exceeding flendernefs and length 5 
juft as if one faw with the naked Eye very fmall Particles 
or Thr'eads ot Wool : From which Obfervation I fup- 
pofed, that in cafe I had put the Water a little thicker to- 
gether, inflead of fpreading it upon the Glafs as thin as it 
was pofiible, the Coagulation of the Salt Particles would 
have been thicker and larger : I concluded too, that mofi: 
of thofe very flender and long Particles were of the fame 
figure as the larger. In (hort, the Salt Particles were-fo 
exceeding numerous, that it is inconcievable by any body 
but fuch as have had a fight of 'em. 
When a great many of thofe very Tranfparent, and as it 
were Cryftalline Salt Particles were become dry, their Tranf- 
parency or Brightnefs did in a manner vanifti, and they 
were changed to Opake Bodies, in which one could not 
perceive the leail Tranfparency, but they appeared to be a 
white Matter.
