' biiity of this new Syficm by Experiments. He faid, tliaf 
having taken the Ventricle and Bladder out of a dead* Bo- 
dy, and filled them with Water, it run all out through the 
Pores 5 and turning them infide outwards, the Water that 
was put in them run thro after the fame manner^ and that 
laftly, Jetting them fwim in Water, it eafily foaked thro 
into them. From which he concludes that in- a living 
Body, it ought to pafs with much greater facility by the 
Tenjion .o{ the Stomach, for ih^ aliment Wk^ a Sponge foaks 
up the Liquor, in which it fvvims, and fo fwells up the Stb- 
machj which in its turn again preffing the Food 5 fqueezes 
out the Liquor from it, and forces it to filter thro itsPores- 
With this preffion it is eafy to conceive, that the Drink 
muft pafs eafier thro the Pores of the 5>^;//^rA than the 
Water, which was put into thQ^tomach taken out of a 
Dead Body 5 and that this Liquor re-enteriqg into the 
Bladder makes the fk^Vrine: it is evident likcwife, that 
this preffion is never ftrong enough to prefs out all the Li-^ 
qnor from the St^mach^ and fo there remains enough to 
carry on the Aliment and Chyle ^ after which it comes away 
high loaded and coloured, and makes what he calls the 
fecond Urines. He added, tl^at the paffage ot the Drink 
into the capacity of the lowerBelly did not caufe thtDrop- 
fie^ becaufe that L/^r^/^r aided by the preiTure of the parts 
that encompafs it, finds an eafie entrance into the Blad- 
der, and none into the intejlines, becaufe of the thick 
Mucus that lines them. The eafinefs of this paflage is the 
caufe that Waters run away fo fuddenly by the 
firft ways, and by the fecond 5 but much more by thefirft, 
when there is but little nourifliment in the Stomach ^ for 
there runs more or lefs Urine by the firft ways than by the 
fecond in proportion to the aliment taken, and to the Sur- 
plus of what is neceflary for the digeftion; refpeft being 
had likewife to what pafles infenfibly by tranfpiration. 
Thy Syftem being fo laid down, hegave.the Reafonsof
