4« I have feveral times endeavoured to obferve the parts of 
a Bone, and at firft I imagined, 1 faw on the furface of the 
Shinbone of a Cow feveral fiBall veins (which bone I ftili keep 
by me;) bat I have not found it fmce m any other bone* I 
thonghc likewife, 1 faw then alH^, that chat Bone confided of 
iinlced Globiils. Afienvards 1 viewed the Shinbone of a 
Ca!f\ in which I found feveral littie holes, paffing from 
wichouc inwards ; and 1 then imagined, that this Bone had 
divers fmail pipes goi-ng longwayes: But I havefinceobferved 
the Tooth a Cow, andfjund irinadeupof traarparent Glo- 
bu!s, which I can fee very perfeftly* The fame I have ob» 
ferved m Ivory o't Elefhmts-teeth, And having feen this fe- 
veral times, I doubt no longer but that all white Bones do 
confift of tranfparent Globuls. Which being fb, I am of o- 
pinion , that all things that appear white to our eyes, 
are made up of nothing but tranfparent particles lying one up- 
on another: Such as are Snoiv, white Paper, Linnen, white 
Stones, whice Wood, Scum, beaten Glafs, beaten Rofin, Su« 
gar, Salt, &c. 
5. Again,! have obferved the Liver of a S/^^f/^/^and that of a 
fat pietorick Cow ; and they alfb confifted of very final] Glo- 
buls, which appeared fo little as thofeof Blood. The Liver 
of the Cow was of a Brown- red colour ; yet viewing it in 
my Microfcope, I found the particles,which f took from that 
Liver, to have but very little colour, only they were a little 
bright towards the red edge, and generally befet with very 
fmall Globuls of blood ; and infome few places thebl )od lay 
vein-wife- Whence I can not ctherwife judge^but that thefe 
fmill particles of blood lay up and down difperfed through 
the Liver out of the veins. I caufed part of thofe Livers to 
be boy led, elteeming, that by reafon of their natural foft- 
nefs, all could not well be obferv'd that might be remarkable 
in it; and lexpofed it to dry fomewhat hard ; and thus in 
both of them I did fee the Globuls : which I intend to obferve 
yet further.
