A statistical study at the Boston Psychopathic Hospital of certain physical and historical data in 1196 cases of schizophrenia, with 836 cases of manic-depressive insanity and 412 cases of general paresis as controls, shows the following results:

The physical findings in schizophrenia are essentially the same as in manic-depressive insanity, whereas the findings in both differ significantly in many respects from those found in general paresis.

Leucocytosis is a frequent finding in schizophrenia but is equally common in manic-depressive insanity and general paresis.

Alcoholism is infrequent in schizophrenic and affective disorders but is more common in general paresis.

Pregnancies, births and living children are fewer among cases of schizophrenia. This appears to be because fewer cases of schizophrenia marry. One reason that fewer marry may be because schizophrenia comes on slightly earlier in life. A study of the number of pregnancies among those who do marry shows that there are as many pregnancies for the schizophrenic group as for the other two groups.
