the Proportion of the hardness of this
Substance. We are now when with respect
to our judging of the relative hardness
of bodies as Men were once of that
of Distance of bodies, and shall even remain
so unless we find a common measure
unless in that we can express it in Numbers
Numbers are what gives us the Idea of the
Proportion could there as aliquots
their use is the being divisible by a
dash of a pen or by imagining that dash
into aliquots. What we want is some
aliquots of the property in question
which can be expressed by numbers.
It would be curious to see how the degrees marked
on a steel spring yard to express the force necessary
to push a given substance into butter, bread, marble,
to discover this relative permeability. Increasing would consist in the form of the Instrument
changing by wear and the best circumstances in the body of heat &c.
