Heredity and Criminal Delinquency 
Heredity is considered only a minor 
cause of delinquency by William Healy, 
director of the Juvenile Psychopathic 
Institute of Chicago, who presents an 
analysis of 823 individual cases in his 
recent book ‘‘The Individual Delin- 
quent.”” Mental abnormalities and pe- 
culiarities appear as a main factor 455 
times and as a minor factor 135 times; 
but Dr. Healy apparently does not 
consider such abnormalities to be the 
equivalent of bad heredity. ‘‘Defects 
of heredity’’ are noted in no case as a 
main factor, but in 502 cases as a minor 
factor. Other causes listed by Dr. 
Healy, such as “abnormal physical 
conditions,’ ‘‘defective home condi- 
tions, including alcoholism,’’ would be 
thought by many students to be largely 
due to defective heredity; and to her- 
edity, therefore, might well be ascribed 
a much more important réle in the pro- 
duction of criminal delinquents, than 
Dr. Healy gives to it, if one used the 
same facts but started with a different 
viewpoint or different definitions. 
An Outline 
BEING WELL-Born, by Michael F. Guyer, 
Professor of Zoology at the University of 
Wisconsin. Pp. 374, price $1.00. Child- 
hood and Youth Series. Indianapolis, 
Bobbs-Merrill Company, 1916. 
The field of heredity in man is 
resurveyed by Dr. Guyer in a com- 
pact volume which omits few topics of 
importance. The study of the cell 
and the mechanism of heredity are 
given much space, and methods of 
cutting off defective lines of descent 
are also dealt with at length. Less 
attention is given to constructive eu- 
genics than one might wish, but the 
of Eugenics 
recommendations made are sound and 
conservative. <A full glossary adds to 
the value of the volume. In the highly 
controversial field of Mendelism the 
author’s conclusions will not always be 
accepted by other students, but this is 
a detail which detracts little from the 
general soundness of judgment shown. 
A comparison of Dr. Guyer’s book 
with those on similar subjects by other 
authors will convince anyone that there 
is substantial agreement between those 
who have studied the problem from 
various angles, in regard to what 
eugenics can and cannot do. 
Eugenics in Hungary 
An organization for Race-Hygiene 
(Eugenics) exists in Hungary since two 
years. Instead of founding a new 
society, existing societies prominent in 
social and medical work organized a 
common Committee for Race-Hygiene 
in Budapest, on February 25, 1914, 
under the leadership of Count Paul 
Teleky and Professor Apathy. There is 
no special organ for publications as yet, 
but the Hungarian Sociological Review 
has a permanent column for topics of 
Race-Hygiene. The work was started 
with the government taking much 
interest in it, when the war broke out 
and stopped further activities except 
an action to repress venereal diseases 
in the army.
