Not illustrated. 1882 Excerpt: .v On multiplying the members of this and the foregoing equation together, we have, Fds = mVdV, which, according to (5). is the value of dQ; hence, (d) dQ = Fds, or, dividing both members by ds, w ( )0 . Secondary principle.--The ratio of the increment of heat to the increment of space in which it passes into the moved matter, is the measure of the phenomena force which accompanies this transfer. It may be mentioned, in reference to the primary principle, that Q is written equal to V2, not in the sense that we have two things equal to each other, but that the first passes into and becomes the second, which, in virtue of this transfer, is then named the vis viva, power or energy of the moving mass, and measured in a mechanical sense by the amount of work which it is capable of doing before it comes to rest, with the matter left as an unexhausted remainder or passive accident. The equation is really between the definite heat Q as the potential or power source on the one side of the equation, with itself in another mode or manner of existence, on the second side! At tbis place I would refer to explanations bearing on this subject which were written by Dr Rankine in 1852, and will be found at page 200 of the edition of his papers already referred to: --"The experimental evidence is every day accumulating of a law which has long been conjectured to exist, --that all the different kinds of physical energy in the universe are mutually convertible; that the amount of physical energy, whether in the form of sensible motion and mechanical power, or of heat, light, magnetism, electricity, or chemical agency, or in other forms not yet understood, is unchangeable: the transformation of its different portions from one. of these forms of power into anoth.<
