Tur Resemsiances AND DIFERENCES OF THE TWO SEXES, by 
M. G, Delaunay.—This is the title of a paper published in the 
Revue Scientifique for September 3, 1881. It has special interest 
as presenting the most complete review of the differential charac- 
ters of the sexes of the human species which has appeared. The 
author's conclusions are curious and instructive. We give a 
necessarily much abbreviated synopsis. 
€ author commences by showing that the female is much 
"iversally the case among Mammalia. This superiority of the 
ale sex consists in the following points: In the male the phe- 
_ 4nd redder, and contains more red corpuscles and hzemoglobine, 
and fewer white corpuscles and less water. Malassez has proven 
that man has a million more red corpuscles in a cubic millemeter of | 
blood than woman. Man eats more than woman. The public 
Charities know that it costs more to feed a boy than a girl, 
Nevertheless though she eats less, woman eats more frequently. | 
In the asylums the women take food from the table, thus doub- 
ing the number of their meals. | De 
Respiration is more intense in man than in woman. Inaman 
- and woman of equal size, the man has a demilitre more pulmonary- 
. n absorbs more oxygen, though he breathes less frequently.

_ Man excretes more carbonic acid than woman. The temperature

_ Pulse is less frequent. The differences in several animals areas
