Summary. Radiographs are presented showing stages in the development of the Munroe effect in an 80 degree cone and a spherical cap, and the projection of soma plane discs. A time scale has been recorded on the radiographs by the use of a detonating fuse clock. In the ease of the 80 degree cone, the formation of jet and plug can be followed from the incidence of the detonation wave, up to about 60 microseconds later, when the jet is some 30 cms. long. The jet from the spherical cap can be followed for 15 cms.
