Neison (now Neville), The Moon and the Conditions and Configurations of its Surface (London, 1876); M.
Let us now consider the effect of this relation upon the configurations and relations of the two planets.
But while the atoms thus differ in quantity, their differences of quality are only apparent, due to the impressions caused on our senses by different configurations and combinations of atoms. A thing is only hot or cold, sweet or bitter, hard or soft by convention (v6,4; the only things that exist in reality (TEfj) are the atoms and the void.
If we now suppose the crevasse produced by direct separation of its walls, the work necessary must be the same as before, the initial and final configurations being identical; and we recognize that the tension may be measured by half the work that must be done per unit of area against the mutual attraction in order to separate the two portions which lie upon opposite sides of an ideal plane to a distance from one another which is outside the range of the forces.
Thus the form of heat or the form of light is the same thing as the law of heat or the law of light."' " Matter rather than forms should be the object of our attention, its configurations and changes of configuration, and simple action, and law of action or motion; for forms are figments of the human mind, unless you will call those laws of action forms."
