N2  - Proton fluxes at atmospheric depths between 10 and 50 g/cm2 have been measured using nuclear emulsions during a series of balloon flights over Melbourne (A = 47° S. geomagnetic) in the period November 1961-April 1962. The proton flux J(x) decreases with increasing depth within this region. It can be represented by the relation log J(x) = (3·05±0·02)-(2·36±0·66)xlO-3x and, when extrapolated, gives the flux at the top of the atmosphere to be 1120±50 protons m-2 steradian-1 S-l.
