Context: Hypothesis Of Molecular Vortices. In thermodynamics as well as in other branches of molecular physics, the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity. (On this subject, see the Edinburgh Philosophical Journal, 1849; Edinburgh Transactions, vol. xx.; and Philosophical Magazine, passim, especially for December, 1851, and November and December, 1855.)

Context: Before war can be fought, a long series of necessary steps, which quite obviously are not and cannot be enforced steps, must be taken by the mass of men. Naval and military budgets must be voted in parliaments and congresses, not just once or twice in a generation but year after year; not secretly, but accompanied by long and public discussion, the budgets being supported by members of parliament, or deputies or congressmen who are still in many states continuously reelected in free and secret franchises, often by great majorities.
