occasional offences, as is also the case with bankruptcies,
defamation, abuse, rural offences, &c., which demonstrate
their more occasional character by their very low figures.

Hence the statistics of general and specific relapse indirectly
confirm the fact that criminals, as a whole, have no uniform
anthropological type; and that the bio-psychical types and
anomalies belong more especially to the category of habitual
criminals and those born into the criminal class, who, after all,
are the only ones hitherto studied by criminal anthropologists.

What, then, is the numerical proportion of habitual criminals to
the aggregate number of criminals?

In the absence of direct inquiry, it is possible to get at this
proportion indirectly, from facts of two kinds. In the first
place, a study of the works on criminal anthropology supplies us
with an approximate figure, since the biological characteristics
united in individuals, in sufficient number to create a criminal
type, are met with in between forty and fifty per cent. of the
total.

And this conclusion may be confirmed by other data of criminal
statistics.

Whilst the statistics of relapse give us a very limited number of
crimes and offences committed by born and habitual criminals,
science and criminal legislation give us a far more extended
classification.
