observations made in Japanese camps for Allied
prisoners of war (6). The malnourished men
tended to become accident-prone due to fatigue and
weakness. Some of -the accidents resulted from
faulty machinery and lack of protective equipment,
e.g., lack of goggles during work in which arc-
welding torches were used. On the other hand,
purposive accidents also occurred; the prisoners
 would intentionally injure themselves in order to
be released, at least temporarily, from work. Nutri-
 tionally they did not gain as the food received by
the sick prisoners was usually less, sometimes only
 hal'f of the ration received by men who were able
•to work. By design these "accidents" were to result
in minor injuries but sometimes the trick proved
only too successful. Thus Curtin reports that one
 prisoner had his right hand and forearm torn and
