In this letter we present the results of the search for massive magnet
ic monopoles in the penetrating cosmic ray radiation using the various
subdetectors of the MACRO apparatus, during the period 1989-1995. Flu
x limits are given for the beta = v/c range 4 x 10(-5) < beta < 1; for
10(-4) < beta < 10(-1) the limits are below the Parker bound, similar
to 10(-15) cm(-2)s(-1)sr(-1). (C) 1997 Published by Elsevier Science
