Summary

Differential equations are given for the stream functions of an unsteady three-dimensional flow in curvilinear oblique coordinates. Cylindrical and spherical coordinates are discussed as special cases. Solutions are given for small disturbances. As an example the stream functions of an unsteady quadrupol and of a source emitting simultaneously are calculated.
