Cretin of Hyrtl col- 

 lection. 



The measurements were taken from the middle of the fronto- 

 malar suture to a line indicating the boundary between the two 

 parts of the bone as defined by the change in texture of the surface. 

 No sutures existed in the specimens selected. 



In the Hyrtl collection of crania, in the College of Physicians 

 of Philadelphia, a Chinese skull (No. 13) showed a complete ex- 

 ternal suture on both right and left sides of body. A Cretin (No. 7) 

 showed a complete suture in the bone of the left side and an incom- 

 plete one on the right side. 



A Siamese skull (No. 39) retained an incomplete partial external 

 suture on both bones, with entire posterior grooves. 



In No. 67 the malar and zygomatic processes nearly met on the 

 posterior surfaces of both bones. A similar groove was seen in a 

 Japanese skull (No. 50). 



Ill a skull (No. 77) a distinct posterior fissure was seen in both 

 bones. 



In a skull of a Hollander (No. 10) a foramen was noted in the 

 maxillo-malar suture. 



The malar bone is thus found to exhibit a disposition for the 

 lower part to become distinct from the upper. The disposition is 

 more frequently seen on the inner than the outer surface, and in all
