differ in their estimate of the aid which may come to the practical
pursuits from a knowledge of the relations as the psychologist
presents them in a non-technical, but yet systematic analysis. Professor

The author of the volume is a distinguished representative of the
modern scientific study of criminology, or ``criminalistic'' as he
prefers to call it. He was born December 26th, 1847, in Graz (Steiermark),
Austria, pursued his university studies at Vienna and Graz,
and qualified for the law in 1869. He served as ``Untersuchungsrichter''
(examining magistrate) and in other capacities, and received
his first academic appointment as professor of criminal law
at the University of Czernowitz. He was later attached to the German
University at Prague, and is now professor in the University
of Graz. He is the author of a considerable range of volumes bearing
on the administration of criminal law and upon the theoretical
foundations of the science of criminology. In 1898 he issued his
``Handbuch fur Untersuchungsrichter, als System der Kriminalistik,''
a work that reached its fifth edition in 1908, and has been
translated into eight foreign languages. From 1898 on he has been
the editor of the ``Archiv fr Kriminalanthropologie und Kriminalistik,''
of which about twenty volumes have appeared. He is a
frequent contributor to this journal, which is an admirable representative
of an efficient technical aid to the dissemination of interest

in an important and difficult field. It is also worthy of mention
that at the University of Graz he has established a Museum of
Criminology, and that his son, Otto Gross, is well known as a
