But the liquid of the jet, having a motion of translation, which carries with it the expansions and contractions, it is during this journey that each of them complete all its progressive modifications.... Further, a fresh quantity of liquid being always supplied, the transformation must be incessantly repeated. Hence the continuous and discontinuous parts of the jet: hence, also, the origination of expansions and contractions scarcely perceptible near the orifice; but becoming more and more developed as they move onwards with the liquid, until the xpansions arriving one after another at the extremity of the continuous part, successively detach themselves, and pursue their course as isolated masses, which assume, or tend to assume, a spherical form: hence, too, the spherules insrposed between these masses; and, lastly, the aws discovered by Savart connecting the length of the continuous part, as well as the tone produced by the shock of the jet, with the change In the diameter of the orifice."--M. Plateau, lowever, does not deny the effect of vibrations, and even musical tones, in accelerating the formation and completion of ventral segments, especially when the expansions and contractions caused by the vibrations coincide with those originating iii the molecular forces. Hydromeleom. The whole aqueous phenomena of the Atmosphere are designated by this name. The chief specific Hydrometeors, viz., Clouds, Deal, fiys. Snow, and especially Rain, are described and their causes investigated under those several titles in our dictionary, and under Hygromktuy; so that it simply remains for u...
