pie that are of that opinion, where that foul Blood can 
remain, fince there are no other PafTages in the Spleen but 
two, viz. one Artery to bring the Blood into the Spleen, 
and one Vein to carry it out. 
Moreover, I inferred a Glafs Tube" into the great 
Vein of the Spleen, and having bound with a Thread the 
Orifice of the Vein, I blew into the Tube, and wonder’d 
to fee how much the Spleen fwell’d with it, and when 
I forbore blowing, the Wind return’d upon me, and the 
Spleen funk which Experiment I tryed feveral times 
with like fuccefi. 
This Experiment is much like the blowing Wind into 
the Lungs of any Animal, which when one leaves off 
returns back again : But forafmuch as in the Spleen by 
accident there was a little Hole, we could not produce 
that effeft without flopping the Hole with one of our 
Fingers 5 and this Experiment I have not only repeat- 
ed in the Spleen of Sheep, but alfo of Oxen and Cows. 
They fay that the Spleen confifts of a fpungy Flefh. 
I muff own I could not difcover that 5 for I allow of 
nothing to be Flefh, but where the Parts are extended 
in length, and lye in a regular order by one another, and 
fo compofe a Mufcle, and the ends of thefe Flefh Parti- 
cles are joyn’d in a Membrane, or make a Tendon of a 
Mufcle j whereas the parts of a Spleen (at leaft as they 
appear tome) fettingafide the Fibrous Parts, the Arteries 
and Veins, are compos’d of very fcnall Particles, which 
were fo exceeding fine, that I could give you no Figure 
of them j and it feemed to me, that as the faid Fibrot s 
Parts, fpread themfelves out into an unfpeakable number 
of very fmail Branches, the faid very fmall Particles are 
depending on the Fibrous Parts. 
One cannot fo feparate thefe fmall Particles of the Fi- 
brous Parts, in order to fet them before the fight, but one 
rnuft break and diffolve not only the very fmall Branches 
of the Veins of the faid Fibrous Parts, but alfo of the 
Veins
