STATISTICS RELATING TO SEVEN 
HUNDRED BIRTHS (WHITE) OC- 
CURRING IN THE PHILADEL- 
PHIA HOSPITAL (BLOCKLEY) BE- 
TWEEN 1865-72. 
BY JOHN STOCKTON-HOUGH, M.D. 
tables were constructed some 
years ago, with a view of obtaining 
j certain facts which have from time to time 
been incorporated in other papers pub- 
1 lished by the author, and are now offered 
I 10 the profession in their entirety for the 
first time. 
These are the only tables I know of in 
which the length of the trunk of the foe- 
tus is compared with the entire length, and 
from an examination of which I discov- 
ered that female children have the trunk 
longer in proportion to their entire length 
than do males,-as may be seen from an 
examination of the table devoted to this 
fact. The weight of the placenta is not 
given ; but I have shown in another paper* 
* " Influence of the Sex of the Foetus on the Condition of 
the Mother during Gestation, Lactation, etc." Amer Jon-i. 
of Obstet., February, March, May, June, 1884, Reprinted, 
8vo, pp. 70, New York, 1884. Oct. 31, 1885]

that observations founded on sixteen thou- 
sand cases show the placenta to be heavier 
in proportion to the foetal mass in the case 
of females than with males,-an explana- 
tion of which may be found in the paper 
referred to. The duration of gestation is 
shown to be longer by three days with 
males than with females. The duration 
of labor was from two to four hours greater 
with males than with females.
