%X A spectrometer for momentum measurements on cosmic ray particles is described. Charged C.R. particles are deflected in the air gap of an electromagnet and the deflection is recorded by an array of G.M. counters. The momentum distribution and positive excess of particles which penetrate 10 cm. of lead is determined over a momentum range 2.4 x 108 eV/c. to 5 X 1010 eV./c. from measurements on 6056 particles.
