rical department of the Philippine General Hospital and one 
other similar operation performed at another hospital (Roxas) 
are not included in this report, for only those cases whose babies 
were born alive per vaginam were measured. Moreover, in all 
Cesarean sections made on Filipino women, only on two occa- 
sions was the disproportion of pelvis and child the indication. 
One was a case of a primipara whose baby had an enormously 
large hydrocephalic head whose mento-occipital diameter mea- 
sured 19 centimeters; and the other, a case of osteomalacia 
(Roxas). The rarity of instances in which pelvic contraction, 
other than that caused by osteomalacia (which was found only 
once) , can be an indication to Cesarean section is emphasized by 
the fact that of the twenty-seven Cesarean sections performed in 
the Philippine General Hospital prior to April, 1918 (Rustia), 
twenty-four were performed on Filipinas for an indication (ex- 
cept in the case of the primipara with a hydrocephalic foetus, 
if that should be excluded) other than the disproportion between 
the foetal head and the pelvis or pelvic contraction. Whereas 
the only Cesarean sections performed on American private pa- 
tients (three cases) were necessary on account of dystocia 
caused by contracted pelvis.
