Thin Liquor may be feparated from ±^ »^i^f, -^^^^ 
oef^iv^ I'lace Let us examine how a Thick Liquor 
may be feparated from the Mafs of Blood whefe thinner Li- 
quors are mixt with it. 
For inftance, let us take the Gdl oxSemen^ 
When the Blood is pufht into the Ce/i^t' 6r Mefenteric 
Arteries, 'tis forced to pafs into the Glands of the Stomachy 
Pancreas^ Spleen and Intejiines^ &c, where the Liquor Ga- 
firicr/Sj Succm Pancreaticm^ Liquor tnteflinalk^ are feparated 
by the above- mentioned method, The Blood thus robb'd 
of various thin Liquors is pu(h'd on into the Veins, which 
anfwer to thefe Arteries, which Veins unite, and form a 
large Trunc called the Vena Porta, which entering into the 
fubftance of the Liver, by its fmall Ramifications chiefly 
forms the Glands of which the Liver is composed. Here 
again all the Fluids contained in the Fena Porta, which are 
thinner than the Bile, are feparated from this Mafs of Blood 
by the firft fort of Secretory Duels ( which we faid opened 
into the Veins) and there are difcharged and mixt with the 
Blood, which is paffing toward the Heart, At the fame 
time th^ Bile, with the reft of the Blood which' is thicker, 
continues its courfe in the Artery ; Now all the thin Liquors 
being feparated the Bile is the thinneft part of this Mafs of 
Blood, and fo may be received by Excretory Dufts, which 
are capable to receive it, and no other. 
The Semeu being a very thick Liquor is feparated much 
after the fame manner, viz. The Blood being puQitinto the 
Spermatick Arteries, pafles into the fubftance of the Tefticlesy 
where all the Liquors that are thinner than that out of which 
the Semen is to be taken are fepiuated by the firft fort of 
Secretory Duds, and carried back to the Mafs of Blood. 
Thea this Liquor Seminalis being the thinneft part of the re- 
maining Mafs is feparated by Encretory Dufts, capable to 
receive it and no ocher. After the Liquor Seminalfs is fepa* 
rated from the M^fs of Blood by the aforefaid method, it is 
pufht forward inco the Encretory Oqds, where there are 
other Diifts, which take their origin allalongirom them,
