A model is constructed of a spherically symmetric self-gravitating condensation of neutral hydrogen immersed in an Hii region. The structure of the condensation is represented by the isothermal gas sphere at a temperature of 100°K. Typical parameters of such a condensation compatible with the estimated ultra-violet radiation field in the central regions of the Orion Nebula are, mass ≈1M &sun;; radius ≈1016 cm; mean density ≈10-15 gm cm-3. The condensations are not static configurations but evolve because of mass loss by ionization from their surfaces. Perhaps 5% become gravitationally unstable and collapse. The remainder act as sources of ionized gas which flows into the surrounding nebula.
