Rh proceeding in the manner laid down by Rankine for a solid of revolution.

§ 79. Typical Cases constituting Solutions to the Equations of Motion.—Some typical cases of stream-line flow constituting the solution to the equations of motion, for the forms of body specified, are given in Figs. 44 (cylinder), 45 (sphere), and 46 (elliptical cylinder). It is scarcely necessary to remark that these forms of flow do not hold good for actual fluids.

In Fig. 47 are plotted the lines of flow for a lamina of infinite
