If dW is the external work done, dH the heat absorbed from external sources, and dE the increase of intrinsic energy, we have in all cases by the first law, dH-dE=dW.
The values of the corresponding functions for the liquid or solid cannot be accurately expressed, as the theoretical variation of the specific heat is unknown, but if we take the specific heat at constant pressure s to be approximately constant, and observe the small residual variation dh of the total heat, we may write F'=s'D+dh+B'.
Either two sounds are confused under one symbol, or these records represent a dialect which, like Hebrew and Assyrian, shows sh, z, and c, where the ordinary Aramaic representation is t, d, and t, the Arabic tic, dh, and th.
The aspirated mediae bh, dh, gh, gh were treated as unaspirated b, d, g, g; probably also the rare aspirated tenues fell together with the unaspirated.
Old 0 and dh frequently become y Old Persian orZend.
