( 1777 ) 
Now, in order to fet before rny own Eyes anew the 
exceeding imall Particles into which Sulphur is divided by 
Fire, I prepared a little Glafs Glohe reprefented by Fig.g, 
A BCD, and placed in it at B5 a fiiiail particle of Sulphar 
about the bignefs of a fingie Corn of S^jid 5 and when 
the Gla(s and the Air within it was fo Temp.erate as to 
agree with the Air we commonly breathe in, J feal'd that 
part of the Glafs which was open at E l-fcrnietical!y,_ and 
then blow'd the Fiame of a Candle upon the other part 
of the Gl'jfs where-the Sulphur hiy, till it evaporated into 
"Srnoak, which Smoak for a fmall fpace of time was car- 
ried sboin the Glais in a Circular Motion 5 and after that 
the Sulphureous Smoak fubfided, and fettled itfelf on the 
Glafi., I examiiVd it with a Microfcope, and obfervsd fo 
many exeee ling fine Particles on the fides of the Gla(s, 
that no man fcarce could believe that fach a foiall grain 
of Sulphur could poffibly be divided into fo nrmy parts- 5 
infornuch that the fmalleft Globules of this divided Sulphur 
could hardly be ieen with one of my beft-GlafieSj and 
the krgeft Globules lay round about the Sulphurecias 
Matter that was not quite diffolved. 
ilet'the Glafs Sphere lye ftdl about half an hoorj and- 
then view'd it ^aoeWg -and obferved with v/onder that 
Come of the fmall Globulcs of Solphur^ that lay a littie 
■remote from the reft", form'd themfelves into a right 
line, arid that 4 or 5 were placed leogthwife, and fonie 
Globules were fo extended in length, that they toucht 
one another ^ but fome hours after they were all united, 
and fo ccmpofed one little body juft like Salt-petre, when 
being joyn'd to Water, it begins to congalate. 
This Inclination or Coagulation was wonderful to me j 
and the more, becaufe fome of thefe Coagulations were 
twice, others three times as long as fome oth ers that lay 
thereabout ^ and juft by thefe coagulated long Particles 
lay other Sulphureous Particles, but none very fmall.
