But though we are unwilling to exa

be made from the Torricellian Experi

preſent Your Lordſhip with a couple of
Advertiſements concerning it.

Firſt, then if in trying the Experiment
here or elſewhere, you make uſe of the
Engliſh meaſures that Mathematicians
and Tradeſmen are here wont to imploy,
You will, unleſs you be forewarn'd of it,
be apt to ſuſpect that thoſe that have writ
ten of the Experiment have been miſta
ken. For whereas men are wont gene
rally to talk of the Quick-ſilver's remain
ing ſuſpended at the heighth of between
ſix or ſeven and twenty Inches; we com
monly obſerv'd, when divers years ſince
we firſt were ſollicitous about this Expe
riment, that the Quick-ſilver in the Tube
