Abstracts
From about 600 pictures obtained with a Wilson chamber in the uniform magnetic field, 32 pictures were found with tracks originated outside of the Wilson chamber and not affected noticeably by the magnetic field. One has to assign to these tracks energies greater than 15000 eV. Approximately calculated ionization effect of these tracks was about 1, the angular distribution shows a sharp excess of tracks directed to large angles with respect to the horizontal plane. One should assign these rays to the secondary electrons created by Hess ultra- rays. It should be stressed that simultaneous appearance of several such tracks occurred from common centers. Possible effects important to theme thods of measuring of "high altitude rays'' and anomalies of "transition zones'' are discussed.
