B. Camel. — The branches are short and thick, the body very long, and the interdental 

 space considerable. The straight border of tlie branches has a posterior rectilinear border, aa 

 in the Horse ; the anterior margin of the curved portion is tliin and sharp. Oa its internal 

 face is seen a plate in front of the superior opening of the inferior dental foramen, and a mylo- 

 hyoid fissure. 



The condyle is convex in front, flat and oblique behind. The coronoid process is very 

 strong. Below the condyle is a process separated from the latter by a deep notch. 



The circumference of the body is excavated by eight alveoli — six for the incisors, and two 

 for the canines. 



C. Pig. — A straight line leading from the greater axis of the alveoli of the molar would

not traverse the posterior border of the maxillary branches , the bottom of these alveoli corre- 

 sponds to the relief on the iimer face. The condyle is compressed on both sides, and elongated 

 from before to behind; while the coronoid process is short and wide. TIjere is no neck; the 

 interdental spaces are very short ; and the maxillo-dental canal opens inferiorly by multiple 

 orifices. 



D. Carnivora.— In Carnivore, this is hollowed at the point corresponding to the insertion 

 of the masseter muscle into a somewhat deep fossa. The posterior border is disposed as in 

 Ruminants, and below the condyle lias a very marked tuberosity. The condyle represents an 

 ovoid segment, and fits exactly into the temporal cavity. The coronoid process is very strong, 

 elevated, and wide. The mental foramina are double or treble. There are no interdental 

 spaces, nor excavated surface on the inner face of tlie branches ; and the latter are never 

 consolidated. 



E. Rabbit. — In the maxilla of the Rabbit, the coronoid process is very short, and the 

 condyle narrow and elongated from before to behind. The posterior border is deeply notched
