Thus was explained the origin of the enormous jaws, strong canines, prominent zygomæ, and strongly developed orbital arches which he had so frequently remarked in criminals, for these peculiarities are common to carnivores and savages, who tear and devour raw flesh. Thus also it was easy to understand why the span of the arms in criminals so often exceeds the height, for this is a characteristic of apes, whose fore-limbs are used in walking and climbing. The other anomalies exhibited by criminals—the scanty beard as opposed to the general hairiness of the body, prehensile foot, diminished number of lines in the palm of the hand, cheek-pouches, enormous development of the middle incisors and frequent absence of the lateral ones, flattened nose and angular or sugar-loaf form of the skull, common to criminals and apes; the excessive size of the orbits, which, combined with the hooked nose, so often imparts to criminals the aspect of birds of prey, the projection of the lower part of the face and jaws (prognathism) found in negroes and animals, and supernumerary teeth (amounting in some cases to a double row as in snakes) and cranial bones (epactal bone as in the Peruvian Indians): all these characteristics pointed to one conclusion, the atavistic origin of the criminal, who reproduces physical, psychic, and functional qualities of remote ancestors.
Subsequent research on the part of my father and his disciples showed that other factors besides atavism come into play in determining the criminal type. These are: disease and environment. Later on, the study of innumerable offenders led them to the conclusion that all law-breakers cannot be classed in a single species, for their ranks include very diversified types, who differ not only in their bent towards a particular form of crime, but also in the degree of tenacity and intensity displayed by them in their perverse propensities, so that, in reality, they form a graduated scale leading from the born criminal to the normal individual.
Born criminals form about one third of the mass of offenders, but, though inferior in numbers, they constitute the most important part of the whole criminal army, partly because they are constantly appearing before the public and also because the crimes committed by them are of a peculiarly monstrous character; the other two thirds are composed of criminaloids (minor offenders), occasional and habitual criminals, etc., who do not show such a marked degree of diversity from normal persons.
Let us commence with the born criminal, who as principal nucleus of the wretched army of law-breakers, naturally manifests the most numerous and salient anomalies.
The median occipital fossa and other abnormal features just enumerated are not the only peculiarities exhibited by this aggravated type of offender. By careful research, my father and others of his School have brought to light many anomalies in bodily organs, and functions both physical and mental, all of which serve to indicate the atavistic and pathological origin of the instinctive criminal.
It would be incompatible with the scope of this summary, were I to give a minute description of the innumerable anomalies discovered in criminals by the Modern School, to attempt to trace such abnormal traits back to their source, or to demonstrate their effect on the organism. This has been done in a very minute fashion in the three volumes of my father's work Criminal Man and his subsequent writings on the same subject, Modern Forms of Crime, Recent Research in Criminal Anthropology, Prison Palimpsests, etc., etc., to which readers desirous of obtaining a more thorough knowledge of the subject should refer.
The present volume will only touch briefly on the principal characteristics of criminals, with the object of presenting a general outline of the studies of criminologists.
Physical Anomalies of the Born Criminal
The Head. As the seat of all the greatest disturbances, this part naturally manifests the greatest number of anomalies, which extend from the external conformation of the brain-case to the composition of its contents.
