The author compares a group of thirty-nine schizophrenic patients who had recovered without shock therapy and an equally large group of patients whose psychosis resulted in deterioration. He tries to work out those features which may make a prognosis possible and finds that psychogenic precipitation, clouding of consciousness at least during the greater part of the psychosis, acute or subacute onset, extraverted personality, and pyknic body type, occur at a mean ratio of 6:1 in the recovered group. A comparison of syndromes, based on an excellent clinical analysis, follows. The paper may be highly recommended for its skilled clinical approach and its careful, pertinent formulations.
