and Laws of xht Hydroftaticks i but as for the latter , the Experi . 
mental proofs^ offered by M* Pafcball for his OpinionSj are by our 
Author eft-cemed fuch,that he confeffes, he hath no mind to make 
nfe of them : for which he alledges more reafons than one; which, 
doubdefs,will appear very fa tis factory to InteHigent Readers. 
Wherefore, inftead of thole Pafcbalian Experiments, there is in 
this Tr^^^//<? deliver'd a far more E:^peditioiis way, to make out, not
