Abstract
A search was conducted for particles of charge (quarks) in cosmic rays at sea level. No such particles were found. The experiment yields an upper limit for the frequency of high-energy quarks of 1 per 2× relativistic mesons. This limit is related to a limit on the quark production cross section as a function of possible quark mass. A short discussion is given of macroscopic experiments which might have detected quarks in matter.
