Aug. 31, 1907. 
The authors controvert the popular belief that idiotic children rarely grow to 
adult life, and as a result of the investigation of 785 cases they conclude that idiocy 
under good care does not seriously curtail life.

Fischer, E. Die Bestimmung der men.schlichen Haarfarben. Korrespondenzblatt der 
deut. Anthropolog. Gesellschaft, Jg. xxxviii. 
A lengthy discussion without fresh chemical or microscopic analysis of human 
hair tints. Fischer makes two series which have a fundamental difference in tone, 
the one being grey black and the other yellow brown. He condemns the scale 
published in this Journal — admittedly somewhat unnatural in tints — because the grey 
shades are absent. Only one such gi-ey shade occurred in the samples collected, 
and it was probablj' of Slavonic origin. Fischer's own scale is prepared from a 
" kiinstlicher GlanzstofF aus Zellulose"; it remains to be seen whether the dye on 
these threads will be permanent and capable of accurate reproduction. The author 
says it may be purchased for 20/- from Franz Rosset in Freiburg i. B., but we have 
been unable so far to procure a copy.

this ably conceived and executed animal census are given.
