ABSTRACT
Psychiatrists, ever since the manic-depressive classification was adopted, have been puzzled by the so-called mixed conditions. The psychological mechanisms which seem to determine these reactions, will be discussed more fully later, when the interrelation of the various manic-depressive psychoses is considered. At this point, however, it may be well, in order to round out our description of manic states, to mention some of the more atypical cases where anomalous reactions apparently occur.
