lie opposite each other, one at the front margin of the parotid and 

 the other at its hinder margin. Another supplementary rjlaml (/), 

 of an elongated oval shape, lies beside Steno's duct and opens into its 

 cavity. It may he distinguished as the facial gland. 



The BubmaxiUary gland (sm) is rather smaller than the parotid 

 and more rounded. It lies behind the angle of the mandible, and 

 is in contact above with the downward prolongation of the parotid

before mentioned. Its duct (called Wbarton's duct) runs forwards 

 beneath the facial vein and opens on the minute salivary papilla 

 before described as being situated beside the frsenum of the tongue. 



There are two accessory submaxillary glands which lie side by side 

 (separated by the facial vein (Fig. 88, jv) immediately adjacent to 

 the lower and anterior end of the principal submaxillary gland. 



Another gland, called zygomatic, is of rather large size and pyra- 

 midal shape. It lies beneath the globe of the eye on the orbital 

 plate of the maxilla and inside the anterior end of the zygoma. 

 It opens in the mouth behind the tipper true molar.
