Modifications of motion considered with reference to the course of the motion in

each case may be distinguished in the first place into those which take place

without actual contact, and those that do not take place without actual contact

between the body or particle in which the motion originates and that to which it

is communicated in the first instance. To the first class /head/ belong

Attraction of gravity, /Gravitation/ /Attractions and repulsions that belong/

Magnetism and Electricity: to the other, Animal motion i:e: motion produced by

volition Attraction of cohesion, the motions in which vegetation consists, and

the attractions called elective and repulsions the investigation of which

belongs to the province of chemistry: to one or the other, as further

examination may indicate /determine/, Galvanism.

Expansion is encrease of repulsion as between particle and particle in a mass of

expanding /-pansible/ matter.

Contraction is diminution of such repulsion.

Expansion and contraction are phænomena accompanying or constituting the passage

of bodies from the state of solidity to the state of liquidity, and from either

into the gaseous state /state of gas/ and vice versa, by the encrease and

diminution of the quantity of caloric or heat.
