There is no subject of such importance as Mechanics, as its principles
are founded upon the properties of matter and the laws of motion; and
in knowing something of these, the tyro will lay the foundation of all
substantial knowledge.
The properties of matter are the following: Solidity (or
Impenetrability), Divisibility, Mobility, Elasticity, Brittleness,
Malleability, Ductility, and Tenacity.
