The topic assigned to me is neuropsychiatry in recruiting and cantonment. However, as my experience has lain chiefly with the latter, I shall confine my remarks to neuropsychiatric examinations in the cantonment. The neuropsychiatric work in the cantonment presents special features which are quite different from those in military hospitals. In the latter, neuropsychiatry is similar to that in civil hospitals, or civil practice. In base hospitals, one finds obvious disorders, chiefly. These have been referred for examination and treatment, by the regimental surgeons, who are, as a rule, not very familiar with such conditions. In the cantonment, the same class of cases is met with, but, in addition, one encounters a special type, which rarely, if ever, finds its way to the base hospital, by reason of the fact that the true character of such disorders is not recognized and very frequently they are regarded as entirely foreign conditions,
