smallest fractional part are the result of excessive intellectual effort; a somewhat larger number arise from structural disease; but the great majority of the insane who have committed or attempted to commit crimes have lost control of their reason because they habitually allowed passion, not reason, to control them. Therefore, we repeat, the greatest possible preventive of crime is to raise a race who shall know how to control their emotional natures through an enlightened will and the habitual exercise of a moral judgment.


IT is well known that from an early period of speculative thought two doctrines have been held with regard to the sort of connection which exists between a man's mind and his body.

Many persons who readily admit in general terms the dependence of mental function on cerebral structure are inclined, when brought to the particular test, to make an exception in favor of the moral feeling or
