[10] Whoever wishes to study the modern professional criminal and his methods should consult Inspector Byrnes’ Professional Criminals of America. It is not a scientific work, and has no reference to anthropologic methods, but it contains a very large and valuable series of photographs of contemporary criminals of note, with a sketch of the career of each.

[11] The classification of criminals adopted in this chapter corresponds substantially with that of Professor Enrico Ferri, by him recognised as provisional. It is also, I find, almost identical with Dr. Colajanni’s.
