A balloon flight to determine the energy distribution and the number of neutrons in the free atmosphere, produced by the cosmic radiation, is described. It is found that there are practically no thermal neutrons in the free atmosphere, in contrast to the fact that near the surface of the ground most of the neutrons are thermal. The number and the rate of production of the neutrons increases rapidly with elevation, in good agreement with previous measurements.
