now to communicate unto you, that fince that time I have feen 
fuch Globuls not only in Mam and Horfe-hair, but alfo fre- 
quently in the Wool of Sheep s and further, that the Root of the 
hair puird out of my Eye-bro'ws confifts altogether of the 
like Globuls. 
4. Having pull'd out of an Elephants- tayl a black Hair,and 
cut tranfverfly from it a thin fcale, 1 expofed it to my Micro- 
fcope, which reprefenred in the thick of that Hair about an 
hundred little fpecks fomewhat whitifh, and in each fpeck a 
.black point, and in fome few of rhofe black points, a little 
hole 3 and this hair confifted withal of united Globuls, which 
yet [thought I fliould have found bigger in this thick hair of 
fo bulky a Beaft, than indeed they were. This Scale I keep 
ftili by me becaufe of its curious and elegant appearance, not 
unlike (excepting the colours) a Peacocks- tayL 
5. 1 have formerly fentyou my way of feeing the motion 
of the Globuls in the Cryftaliin liquor of the Blood : Having 
fince contrived a more convenientGIafs-pipe for that purpofe, 
J cannot but give you and your Curious Friends notice there- 
of ; 1;/^. A B is a hollow Glafs-pipe from B to 0,a- ^^^^ ^ 
bout the thicknefs of a courfe horfe-hair ; from O * 
to D, about the thicknefsofa Pigeons quil, and the thicknefs 
from D to A fomewhat flenderer, ad flacitum, 'Tis open on 
both its ends, A and B ; Into this pipe I brought fome Blood ^ 
from E to F, or from E to C, and then feal'd the end A herme- 
tically: Orelfe, I leavethepipe clofedat A, and by the ap- 
plication of my hand or breath bring a little warmth to the 
thickeft part of the Glafs G, holding the pipe with my two fin- 
gers at F5 and fo conveying its open end B to the Blood, 
Whereupon fome of the Air in the pipe, being by the faid 
warmth driven out at the open end B, it will immediately in- 
deavour to have its former fiate, and fo attraft a little blood 
into the flenderer part of the pipe: which pipe I then put from 
'A to G into a fmall Copper-pipe, which I had caufed (o be fit- 
ted to one of my Microfcopes, and which I can move at^plea- 
]fure, nearer or further ofF,higher or lower. 
6. I did lately view f fome Blood, in which . , c,l ^ 
there was much of that CryftaUm liquor, and y dcfcrMpipes.
