5 THE TOXER LECTURES. 



In all of these specimens a delicate line could be traced forward 

 from the posterior to the antero-inferior portion of the bone. It 

 was of precisely the same character in the examples in which the 

 outer suture was distinct. 



The inner surface of the malar bone will not infrequently exhibit 

 a concavity below the line of the suture. This concavity is distinct 

 even in specimens in which the suture is nowhere evident. Such a 

 peculiarity is well seen in a Peruvian skull (No. 1407). A similar 

 disposition was noticed in the skull of the Hyrtl collection (No. 92). 



The small ossicles named above as occurring at themalo-zygomatic 

 suture tend to break up the uniform smooth surface of the inner 

 aspect of the malar bone — a disposition which may exist even in the 

 absence of a separate ossicle. The squamosal element may be long 

 and irregular and extend forward, along the line occasionally taken 

 by the suture, nearly to the maxilla.^ This was seen in a Peruvian 

 (No. 1506), which showed an incomplete sutux*e externally, and in 

 the skulls of two Creek Indians (Nos. 652 and 75). 



The following measurements were made to indicate the propor- 

 tionate size of the upper and lower parts of the malar bone. The 

 numbers have been arranged in the order of the size of the upper 

 part of the bone, this being the smallest in the first example named 

 and the largest in the last :

 attention to this subject as studied in modern European crania.
