The results that have followed this treatment have been published elsewhere.1 Seriously sick patients of these types are relatively uncommon, and it will be some time before a number sufficient to report can be studied carefully in the manner outlined below. In the meantime, in order to learn more of the mechanism causing these results, it seemed essential to study the effects which these therapeutic procedures have on normal individuals. Two observations, in the course of our work with normal subjects, seem of sufficient interest to report at this time.
