Referring to phenomena of mass as gravitation. Mechanics
generally treats of molar laws and phenomena.
[Transcriber's note: Molar, or mole, often refers to a quantity of a
substance containing an Avagadro number (6.02E23) of molecules--a weight
equal to the atomic weight of the molecule. For example, a mole of
hydrogen (H2) is 2.015 grams; sodium chloride (NaCl) is 58.443 grams.]

Contraction for millimeters.

A proposed but not adopted unit of current; one-thousandth of an
oerstedt. It is equal to one-thousandth of an ampere.
[Transcriber's note: oersted: 1. CGS unit of magnetic intensity, equal
to the magnetic pole of unit strength when undergoing a force of one
dyne in a vacuum. 2. Formerly, the unit of magnetic reluctance equal to
the reluctance of a [...]
