The Great Unmarried 
adult life, as a part of social hygiene, 
must begin with a new canonization of 
marriage. This is the task equally of 
the fervent poet and the scientific 
thinker, whose respective labors for 
humanity are never at variance in 
essentials. The sentiment for 
marriage can be deepened by a rational 
understanding of the passion that 
attracts and unites the sexes. We need 
an apotheosis of conjugal love as a 
basis for a new appreciation of marriage. 
Reverence for love should be fostered 
from the outset of the adolescent period 
561 
by parents and pedagogues. The spiri- 
tual import and the beauty of the 
love of the sexes should be revealed, and 
a sense of worship instilled in young 
minds.” 
“From rude, primitive sexual pairing 
there has grown a supremely entrancing 
and tender idyllism that is the most 
potent of all spiritualities and a strange 
miracle of daily life. The true votary 
and venerator of marriage is the man 
or the woman who strives through 
knowledge to elevate marriage, and to 
make that state holy and exemplary.”’

MINDED, by Alfred Binet, Sc.D. and Th.

The Training School has done a real 
service by publishing these two volumes, 
which contain a translated collection of 
practically everything that Drs. Binet 
and Simon wrote on the measurement 
of intelligence. The first volume con- 
tains a complete explanation of the 
scale in its various stages of evolution; 
the second shows the operation of the 
scale in the hands of its authors as they 
used it in the study of the feebleminded, 
dements, and speech defects. 
The Binet-Simon tests are so familiar 
now that it is hard to realize that the 
first publication on them dates back only 
to 1905, and that it was several years 
later that they were first heard of in 
America, when Dr. H. H. Goddard, 
who contributes an introduction to 
the first of the above volumes, had 
made use of them in his own work with 
successful results. Many of the criti- 
cisms since made would never have been 
made if the complete work of Binet and 
Simon had been known, and the present 
publications should serve to place the 
measurement of intelligence on an even 
more solid foundation than it at present 
has. 
Mental Effects of Inbreeding in Rats 
Albino rats inbred for a _ dozen 
generations have been tested at the 
Harvard Psychological Laboratory by 
Mrs. Ada W. Yerkes, with a view to 
finding whether they differ mentally 
from rats that are not inbred. They 
were studied in a maze, and the dis- 
tances they traveled and the time they 
required to find their way through were 
noted. The conclusions presented in 
the Journal of Animal Behavior (Vol. vi, 
No. 4) show, in general, a little more 
slowness in learning on the part of the 
inbred rats. “This slowness seems 
chiefly to have been due to a greater 
timidity and a greater susceptibility to 
environmental conditions.’ In some 
tests, however, the inbred rats excelled. 
The study does not, of course, show that 
inbreeding necessarily produces any 
mental or physical inferiority. If there 
were inheritable factors for timidity, 
the inbreeding would intensify them 
and distribute them to all the rats, which 
might result in such conditions as Mrs. 
Yerkes found.
