  A very recent observation by the Auger Observatory group claims strong
evidence for cosmic rays above 56 EeV being protons from Active Galactic
Nuclei. If, as would be expected, the particles above the ankle at about 2 EeV
are almost all of extragalactic origin then it follows that the characteristics
of the nuclear interactions of such particles would need to be very different
from conventional expectation -- a result that follows from the measured
positions of 'shower maximum' in the Auger' work. Our own analysis gives a
different result, viz that the detected particles are still 'massive'
specifically with a mean value of <ln A> = 2.2 +- 0.8. The need for a dramatic
change in the nuclear physics disappears.
