 that this must represent some element which tends to remain separate".

 in a female skull as representing maxillo-frontal ossicles such as those 

 described by Macalister. Ranke, however, considers them as nothing 

 more than ossicles developed in association with a fontanelle which 

 is present in early foetal life between the nasal, frontal, lachrymal,

Recently, Zabel (7) has recorded three human skulls in which 

 the Ossiculum maxillo-frontale was represented. 



That supernumerary bones in association with the anterior part 

 of the lachrymal bone are not confined to the human subject is clearly 

 evident from several recorded instances of their presence in other 

 mammals. Macalister (5) makes mention of an ossicle in the pig, 

 apparently normal in occurrence, which is late in ossifying, only showing
