. The comparative anatomy of the domesticated animals. Veterinary anatomy. THE HEAD, 65 Fig. 36. 6. Temporal hone.—In tlie squamous portion of the temporal bone of Man, the zygomatic process only rests on the malar bone, as in ruminants. The glenoid cavity is concave in every sense, and divided into two parts by an opening named the fissura Glaseri; the anterior portion only is articular, the posterior lying against the external auditoiy canal, does not belong to the articulation ; it corresponds to the eminence of the Horse. The tuberous portion is consolidated with the squamous. It is divided into a mastoid and a pyrnmidal portion; the latter comprises, in its turn, the petrous and tympanic portions. The mastoid i portion corresponds to the mastoid process, mastoid protuberance, and superior border of the petrous bone in the Horse. It presents' a rugged mastoid process; above this is the mastoid canal; and above and behind it, the digastric groove; the pyramid forming a con- siderable projection in the interior of the cra- nium. The styloid process or bone is altogether separate from the other pieces of the hyoid, and in the adult is consolidated with the temporal bone, 7. Supermaxilla,—In Man the prema^xilla is no longer found independent, the centre which forms it coalescing with the supermaxiilary bone. The supermaxilla of Man concurs, for the greater part of its extent, to form the floor of the orbit; it is also divided into three faces: an external or facial, a superior or orbital, and an internal or naso-palatine. The external face presents, from before to behind: 1, A small fossa, into which is inserted the myrtiform muscle; 2, The infraorbital, or canine fossa, showing the inferior orifice of the infraorbital canal; 3, A crest corresponditig to the maxillary spine of solipeds; 4, The alveolar tuberosity. This fwce carries, in front, a prolongation that forms the ascending process, also named, be- cause of its relation, the Ironto-nasal
