The easiest method of 
bringing out the mixture 
of types is by plotting 
measurements mn: es 
graphic way, so that the 
resulting curve will show 
the proportion or per- 
centage of individual 
cases of any and all 
particular types. The 
measurements of the one 
thousand two hundred 
thirty-seven pelves on 
which the present paper 
is based have been plot- 
ted in such’ graphic 
curves. For the whole 
number of cases. the 
curves for each measure- 
ment are shown in figs. 
1 to 5. 
This investigation has 
shown that we are able 
to isolate three major, 
and two minor, types of 
Philippine pelvis, as has 
just been demonstrated. 
To associate any of these 
types of pelvis with par- 
ticular racial varieties 
of man would be folly in 
the present state of our 
knowledge (or rather 
ignorance) of the other 
races of Oriental peoples, 
who surround the Philip- 
pines.
