An account is given of experiments on the momentum spectrum of the particles in extensive air showers at sea-level. The results are consistent with an integral spectrum of the form N (> E ) α ( E + E c ) -(1.1±0.3) , where E c is the critical energy in air. Penetrating particles are found in some of the denser showers, the ratio of penetrating particles to electrons being (0.8±0.4)%.
