in orbits which are mainly formed by the alisphe?ioids, orbito- 

 sphenoids^ frontals and other bones, but the anterior corner 

 is completed by a lacrymal bone which develops especially in 

 connection with the eye. 



The nasal capsules have several bones which are thin and 

 coiled in order to present a large surface. They are called 

 the turbinals and are attached to the ethmoid, nasal and 

 maxilla. Hence they are called ethmo-^ naso- and maxillo- 

 turbinals.

These all form the cranium, and to them are added 

 a number of bones which arise in connection with the first 

 two visceral arches and form the main part of the facial 

 region. The premaxilla and maxilla form all the anterior 

 region of the skull below the nasal chamber. Above the 

 maxillae the small vomers are found. They are hidden by 

 the palatine processes of the maxillae. The palatines and 

 pterygoids lie in the roof of the mouth. The squamosal is a 

 large and important bone which lies between the auditory 

 bones and the sphenoid ring ; it has a glenoid cavity for the
