of the Skeleton of an Ourang Outang. 187 
The nasal bones are wanting, giving him that flat or simous 
appearance, from which is derived the term simza, to distin- 
guish the ape species. 
_ The maxilla superior and inferior are very prominent, which 
makes the facial angle more obtuse than the African. 
The frontis is somewhat high and projected. 
The inferior maxilla is closed at the mentum, which is a 
little angular and projecting. 
The teeth consist in each jaw of two dentes incisivi; the 
two middle of the upper jaw are very long and broad, mea- 
suring seven-eighths of an inch in length, and five-eighths in 
breadth. The two lateral have not yet fully grown; two cus- 
pidati, and four molar teeth; making in all, twenty-eight. 
The four incisores are new and permanent teeth; the cuspi- 
dati had not been shed. 
The first molar in each jaw was just giving place to the bi- 
cuspid. 
The last molar in each jaw are permanent teeth, the others 
were about being shed. 
I should judge from the teeth, that this individual was about 
five and a half years old. 
The spine consists of twenty-three vertebra, viz. seven of 
the neck, twelve of the back, and four of the loins. 
The neck is short, being but three and a quarter inches in 
length. The vertebrae composing it are flatter before, and not 
so round, having their spinous processes much longer and 
rounder than in man. 
The first vertebra of the neck has.no spinous process, being 
in this respect unlike the human, which has a small one; but 
anteriorly, it resembles man, and differs from the monkey, in 
having an eminence rather than a fissure. 
The second vertebra has the processus dentatus long, and 
partly cartilaginous; the transverse processes are so also. 
The vertebree of the back are like those of man; they mea- 
sure eight inches and three-quarters. 
The vertebrae of the loins are three inches in length. They 
have their transverse and spinous processes short and thick, 
like man’s. 
The ilea are very flat, and are articulated to the sacrum 
asin man. ‘The sacrum differs materially from the human, 
being more flat and narrow; it consists of five bones, con- 
nected by cartilage. Indeed, the whole pelvis exhibits a more 
striking difference from the human than any other part of the 
skeleton. ‘ 
The ileum measures from the anterior superior spinous pro- 
cess to its junction with the sacrum, three inches,
