A CLINICAL STUDY OF THE SKULL. 7 



States Army Museum (No. 309, Chickasaw) the malar bone was 

 double on both sides.^ 



Four examples were seen in which a suture began at the malo- 

 zygomatic suture, and, advancing forward, was lost a short distance 

 from the posterior end of the bone. These were No. 1424, Peru, 

 on both right and left sides; No. 1506, ibid, on the right side, and 

 No. 1434, ibid, on both right and left sides. 



In a single example. No. 1369, ibid, a skull of an old female, a 

 foramen perforated the right malar bone a little in advance of the 

 malo-zygomatic suture and appeared to be in the line of the trans- 

 verse suture, though no trace of the line could be discerned either 

 in front or back of the opening. 



Thus twelve examples can be cited, all of American origin, which 

 exhibit transverse malar sutures more or less complete as seen from 

 both the inner and outer surface of the bone, and two in which the 

 bone was double. 



But when the inner side of the malar bone is examined a much 

 larger number of skulls exhibit the transverse suture. No attempt 

 was made to ascertain the entire number of examples last named. 

 AVhile a search was instituted, with another object in view, the inner 

 surface of the malar bone was at the same time examined, and out 

 of the entire number examined, it was detected in fifty-one crania. 

 In eight of these it existed on both right and left sides. 



The distribution of selected examples among the races was as 

 follows : Nox'th American Indians, one each of Chinook,'' Lenape,^ 

 Menominee,* Naas,^ Shawnee,^ California Indians,' one unnamed ; ® 

 Peruvians, ten ; ® Anglo-American, one • '" Mexicans, three ; " negro, 

 one;^^ Egyptians, five;'^ Circassians,^' Roman,^^ Arabian, '^'^ Nu- 

 bian,^' one each. 



'I have since seen an additional example in a skull (No. 53) in the ana- 

 tomical collection of the University of Pennsylvania.
