the form of the head nothing certain is as yet known ; but it appears 
to have been proportionally longer than that of the elephant. 
Mr. Peale was the first who ascertained that this animal was pro- 
vided with tusks, by discovering the remains ofaskull already mentioned, 
in which the alveoli were evident. These tusks resemble those of the 
elephant ; they are inserted in the incisive bone, and are composed of 
ivory, the grain of which shows curvilinear lozenges, enveloped by a 
substance, which is not of the texture of ivory, but is formed of fibres 
converging towards the centre ; and which, though less hard than the 
enamel, seems very nearly to resemble that substance. Mr. Peale had 
been disposed to place the tusks of this animal in a situation the 
reverse of that which they hold in the elephant ; that is, with their 
convex part forwards, and the point turning backwards ; but no cir- 
cumstance but the finding a skull, with the tusks thus disposed, can 
authorize the placing of them different from those of the elephant. 
From the circumstance already noticed, and from every considera- 
tion of the subject, there appears to be no reason for doubting that 
this animal had a trunk like the elephant, with whom it agrees in so 
many respects. 
The form of the vertebras agrees in general with that of the corre- 
sponding vertebrae in the elephant. The ribs are formed different 
from those of the elephant, being thin towards the cartilage, and thick 
and strong towards the back. The six first pair are very strong in 
comparison with the others, which also become, proportionally, very 
short: which circumstance, taken with the depression of the pelvis, shows 
that the belly was less voluminous in this animal than in the elephant. 
The scapula appears to possess the characters of the scapula of the 
elephant, and particularly the recurrent apophysis peculiar to this genus, 
and to the rosores ( rongeurs ) . The scapula seems to be narrower than 
even that of the African elephant, and to have the recurrent apophysis 
placed higher than in the Asiatic elephant. The length of the scapula 
is three feet and one inch. Mr. Peale describes the acromion as being
