The next thing therefore that we are
to enquire after, in order to our preſent
deſign, is the difference in weight betwixt
Water and Quick-ſilver: And though
this hath been defin'd already by the Il
luſtrious Verulam, and ſome other inqui
ſitive Perſons, that have compar'd the
weight of ſeveral Bodies, and caſt their
Obſervations into Tables, yet we ſhall
not ſcruple to annex our own tryals about
it: Partly, becauſe we finde Authors
conſiderably to diſ-agree; partly, becauſe
we uſ'd exacter Scales, and a ſomewhat
more wary method then others ſeem to
have done: And partly alſo, becauſe ha

three ſeveral ways; the ſmall difference
