We have studied the individual pulses from PSR 1055–52, a pulsar which has a strong interpulse. Their properties, and those of the average pulse profile are consistent with an emission geometry in which the magnetic and rotation axes are nearly perpendicular. That is, we are observing both magnetic poles of this pulsar. A correlation between the emission from the two magnetic poles was found wherein a strong interpulse is followed by a strong main pulse. Also, the main pulse appears to undergo mode changes that are primarily characterized by a change in the peak flux density of component I.
