"The type of a species," adds Isidorus St. Helaire, "never appears before our eyes but is perceived only by the mind." "Human types," writes Broca, "have no real existence, they are only abstract conceptions, ideals, which come from the comparison of ethnic varieties, and are composed of an ENSEMBLE of characters common to a certain degree among themselves."

there are many persons of distinctly criminal instincts who are kept in the paths of honesty merely by circumstances

The following typical peculiarities have been noticed by different criminologists:

Feeble cranial capacity; heavy and developed jaw; large orbital capacity; projecting superciliary ridges; abnormal and assymetrical cranium; the presence of a median occipital fossa.

Habitual homicides have a glassy, cold, immobile, sometimes sanguinary and dejected look; often an aquiline nose, or, in other words, a hooked one like a bird of prey, always large; the jaws are large, ears long, hair woolly, abundant and rich (dark); beard rare, canine teeth, very large; the lips are thin.

we should study the criminal and ask ourselves "what is he?" and "of what forces is he the product?"

Man has two natures, the animal and the spiritual.
