reveals in them an inferiority of form and histological type,
gives also, in a great majority of cases, indications of disease
which were frequently undetected in their lifetime. Thus M.
Dally, who for twenty years past has displayed exceptional acumen
in problems of this kind, said that ``all the criminals who had
been subjected to autopsy (after execution) gave evidence of
cerebral injury.''[3]

Observations of the physiognomy of criminals, which no one will
undervalue who has studied criminals in their lifetime, with
adequate knowledge, as well as other physical inquiries, external
and internal, have shown the existence of remarkable types, from
the greater frequency of the tattooed man to exceptionally
abnormal conditions of the frame and the organs, dating from
birth, together with many forms of contracted disease.

Finally, inquiries of a physiological nature into the reflex
action of the body, and especially into general and specific
sensibility, and sensibility to pain, and into reflex action under
external agencies, conducted with the aid of instruments which
record the results, have shown abnormal conditions, all tending to
physical insensibility, deep-seated and more or less
absolute, but incontestably different in kind from that which
obtains amongst the average men of the same social classes.
