No. 424] DIVISION OF THE MALAR BONE. 277 
The two malars differ considerably in size, the left one being 
higher, but narrower, than the right one.

Highest point of fronto-malar suture vertically downward to

A line between the most iliis ien of the malo-maxillary 
and the zygomatic suture, 2.7 cm. 3.2 cm. 
This excess in height and deficiency in breadth of the fully 
divided malar when compared to its mate is in full accordance 
with previous observations on this point. A relative narrow- 
ness of the inferior of the two portions of the divided malar is 
also more the rule than the exception. 
The incisures in the right malar have apparently influenced 
the growth of that bone but little. The evidence of the 
measurements is against their equivalence with the complete 
division on the right. If these incisures are remnants of a 
complete division, the measurements indicate an early union 
of the middle portion of the malar. 
The presence of the frontal division has ipie» no relation 
to that in the malar bone. A persistent metopic suture is 
present in 97 of the 492 Peruvians, without there being another 
case of a complete 
malar division ; there 
is also in these skulls 
no excess of malar 
incisures.

Orang. — The skull is 
that of a young orang and is a part of a mounted skeleton in 
Professor Huntington’s museum in the College of Physicians 
and Surgeons, New York City. Besides the malar divisions 
the specimen shows nothing unusual. 
The malar sutures are in every way much alike on the two 
sides. They run each with a moderate double curve from near
