The common difference of the palatal, the coronal, the basi- 
lar, and the extreme lengths of the cranium, is the breadth of 
the cranium at the temporal fosse: these lengths in the animal 
examined being respectively

In the accompanying Tables, the dimensions of the bones of 
the neck are very minutely stated. This minuteness will be 
deemed the less superfluous, if it be considered that these bones, 
from their remarkable size, may be viewed as an enlarged re- 
presentation of the type of the similar bones of the human body 
and in other mammalia. 
The dimensions of the atlas and of the second vertebra of the 
neck are, on account of their great importance, given apart; 
and an endeavour has been made to trace the correspondence 
of their dimensions with the dimensions of the other cervical 
vertebrae. | 
The lateral extent of the atlas is equal to the distance 
between the inner margins of the orbits. The atlas, besides
