I caufed a very fmall Particle of the forementloncd 
'Parts to be drawn, fo as it appear’d to the naked Eye, as 
you may fee in F/g. K, L, M, N ; only with this dif- 
ference, that that which is drawn is not fo thick and 
large as it diou d be, becaufe the Parts were dry’d and 
flirunk in, and they were moreover of the fmalleft fize 
of any that I had diifefted. 
Fig. 4. O, P,Q,R, S,T, is a very fmall piece of the 
foremention’d Particle,- which was Ifrip’d of its fecond 
Skin, and in which fome few of the pointed Parts were 
ftanding out, but mod part of them lie clofe upon the 
faid Particle. , , « 
I obferved, that that pointed part, reprefented by S, 
ftoodout longer* than the reft, and thatit wascompofed 
of feveral long Particles united together, the longeft of 
which was ftanding out above the reft, and ran into 
ftich fharp Points, that they appeared thro’ the Micro- 
fcope juft as the Point of the fmalleft Sewing Needle- 
does to the Eye ; and the reafon why we caiPt fee tliefe 
ftiarp-pointed‘ Particles always in each part, is in my O- 
pinion, becaufe they are fo united to the two Skins, with 
which they are as it were Cover’d, that they can’t be fe- 
parated from them without leaving-fome part ftickingin 
one or other of them ^ I have alfo. obferved fome, of 
which the extream Parts confifted of four diftinft Points 
of equal length. . , t' n 
In fome of thofe {harp Particles that are ftanding out 
in Fig. 4. fuchfor inltance as are deferibed by Q^nd R, 
we cou d fee very plainly, that each of ’em confifted of 
three long Particles, the middle of which was the long- 
eft ; from whence I confidered, whether each of thole 
long Particles were compofed of other long Particles, 
which, upon the Account of their exceeding fmallnefs, 
might efcape our fight.
