He also admits himself that mental evolution exemplifies integration of matter and dissipation of motion only indirectly.
The results obtained as to the relation between dissipation and barometric pressure are conflicting.
The loss of the dissipation body due to the natural ionization of the air is first allowed for.
This general law, known as the principle of the "dissipation of energy," was first adequately pointed out by Lord Kelvin in 1852; and was applied by him to some of the principal problems of cosmical physics.
Universally as an " integration of matter and dissipation of motion," and yet mental, social and moral developments are also called evolution, so that, in accordance with the definition, they are also integrations of matter and dissipations of motion.
