off 5 Our Noble Author in lifts ruoft upon giving us his thoughts of 
the fo rnier, videl. the y Equilibrium of Liquors: Which Difcdurle cone 
filling partly of Conclufions, and partly of Experiments, the former 
feem to Him, to be almoft all of them confonant to the Principles* 
and Laws of the Hydtofl aliens ; but as for the latter , the Experi- 
mental proofs, offered by M. Pafchall for his Opinions,. are by our 
Author efteemed Inch, that he confeifes, he hath no mind to make 
ufe of them ; for which he aliedges more reafons than one; which, 
doubtlefs.wiil appear very fatisfadlory to Intelligent Readers. 
Wherefore, inftead of thole Fafchalwn Experiments, there is in 
this Tnatife deliver’d a far more Expeditious way, to. make out, not 
mi ly moll of the Conclufims , agreed on by thefe two Authors, but o- 
thers alfo , that M Pafchall mentions not » and that with fo much 
snore eafe and clearnefs,thatperfons, but ordinarily verfed in the 
common principles of Hydrojlatieks , may readily apprehend, whaE: 
is delivered, if they will But bring with them a due Attention, and 
Minds difpofed to prefer Reafon and Experience to Vulgar opi- 
nions and Authors. 
It not being our Authors prelent Task, to deliver a Body of 
L$yd reflations, but only fome Paradoxes, which he conceives to be 
proveable by his New way ot making them our, he delivers them 
'in as many diftindt Propofttions after each of which, he endea- 
vourSgina Proof, or an Explication 3 to fhow,both that it is true, and 
why it ought to be fo, 
Th q Paradoxes themfelves ( after a premifed foflulatum ) are 
thefe : 
1. That in Water, and other Fluids, the Lower parts are pref- 
fed by the Upper. 
2. That, a lighter Fluid may gravitate or weigh upon a 
heavier. 
3. That, if a Body, contiguous to the Water, bealtogether,or 
in part, lower than the higheft level of the faid Water, the lower 
part of the Body wifi be preffed upward by the Water ,that touch- 
es it beneath . 
4. That in the Afcenfion of Water in Pumps, .there needs 
nothing to raife the Water, but a Competent weight of an Exter- 
nal Eluid. 
5. That the preffureof an External Fluid is able to keep an 
Heterogeneous Liquor fufpended at the fame height in feveral 
Kpesjthough thefe Pipes be of very different Diameters.
