, — ,lected. It was shown in the paper mentioned that when two shock waves meet, or when a schock wave is met by an expansion wave, special frontiers will appear at which there is a change of the entropy of the gas. It will be the object of the present lines to show that a similar phenomenon occurs when a shock wave is met by sound waves.

Preliminary Measurements of the Distribution of the Velocity of a Fluid in the Immediate Neighbourhod by the action of the frictional forces. The layer of fluid immediately in contact with the surface will adhere to the latter, and so, the body being supposed at rest, its velocity will be zero; the adjacent layers have velocities increasing with the distance from the surface, and a layer of a cert

In connection with the latter point it is necessary to recollect that the point of view taken in constructing an equation which should govern the various possible “states” of the turbulent motion, had been shifted during the course of

Introductory Remarks on Recent Investigations Concerning the Structure of Liquidse problem of the internal structure of liquids. It does not lie upon our way to give a comprehensive picture of the present position of the latter problem; in connection, however, with various points to be considered in the subsequent chapters it may be useful to collect a few remarks of a more gene
