The caloric test was performed, that is, each ear was douched with cool water. They were also examined in the turning-chair, and in addition the galvanic

Four subjects were turned in the same manner twice daily. Two subjects had many additional turnings, as much as 440 rotations in one day. The results of the nystagmus reactions in these cases are given in Table 2 . Throughout these tests it will be observed that now and then a day was skipped. This could not be avoided, since all of these subjects were enlisted men who because of other duties occasionally could not appear for the examination. These lapses, however, were so rare-about one day in seven-that they certainly have no effect on the findings. These records clearly indi¬ cate that :
