Abstract: It is shown that if $ P$ is a linear partial differential operator with analytic coefficients, and if $ M$ is an analytic manifold of codimension $ 3$ which is partially characteristic with respect to $ P$ and satisfies certain additional conditions, then one can find, in a neighborhood of any point of $ M$, solutions of the equation $ Pu = 0$ which are flat or singular precisely on $ M$.
