to the superior margin of the hyoid bone. This process ventrally becomes fused with the peri- 

 mysium of the ventral belly of the digastric. Dorsally it extends over the posterior end of the 

 submaxillary gland and becomes attached to the angle of the jaw. Here it is strengthened by 

 fibrous tissue which extends in from the ventral margin of the sterno-cleido-mastoid and serves 

 to separate the parotid from the submaxillary gland. This 'mandibular process' is continued 

 into the stylo-mandibular Ugament.

 in places in order to show the deeper /ascice; the sterno-cleido-mastoid has been partly removed; 

 the submaxillary gland, almost wholly ; the parotid gland, as far as the duct.

'J"li(! parotid gland is enclosed between two lamina^ of the external cervical fascia. These 

 arc continued over the gland from tlie fascial investment of the sterno-cleido-mastoid, and unite 

 ventrally to become fused to the masseteric fascia along the anterior margin of the gland. 

 They unite l)elow the inferior margin of the gland, and are continued into the mandibular process

 to the cartilage of the auditory canal and to the zygoma. The inner lamina is attached above
