  The SIMPLE Collaboration has reported results from their superheated C2ClF5
droplet detectors, including a description of acoustic discrimination between
\alpha decays and nuclear recoils. Our concern is that the events in the
neutron calibration data and the events identified as neutrons in the physics
data are not drawn from the same parent distribution. This fact calls into
question the identification of the background events as neutrons, the use of
the calibration data to define the acceptance of WIMP-induced nuclear recoils,
and the observation of discrimination against \alpha's.
