The paper considers the flow which results when a slit of finite width is suddenly opened in a large container and a jet of fluid issues into free space. The early stages of the motion are discussed by expanding in powers of time. It is suggested that the jet boundary may be M-shaped initially. The shape of the jet after large but finite time is calculated by the general theory of part I to have a kink at the nose. However, by expanding in powers of the distance across the jet, the true radius of curvature of the nose has been evaluated. A realistic shape of the jet is sketched in figure 3.
