is moulded on to it. We liave verified this relation by pressing 

 „Plasticine'' into the Parotid bed after removal of the gland, and have 

 thus been able to verify at the same time its actual relation to the gland. 

 We may say that the Parotid extends inwards as far as the process 

 and as a rule no further. The presence of a pharyngeal process 

 (vv^bich we have never seen) running inwards in front of the Styloid 

 and Styloglossus muscle would naturally bring the gland into closer 

 relationship and might cause a marked impression to be left upon it. 

 Such a condition is beautifully 

 figured by Testut and Jacob (5),

Mastoid Area 



In our own specimens we 

 failed in every case to demonstrate 

 the wide bold Styloid groove figured 

 by Parsons (1). This relationship 

 that we have described, with the 

 Parotid gland extending inwards as 

 far as the Styloid and no further, 

 we consider the normal condition: 

 it is well shown in figs. 9 and 10 

 of Symington (loc. sup. cit.), also 

 in figs. 383, 384, 386, 390 of 

 Poieieb's account of this salivary 

 gland in Poirier and Charpy's 

 Anatomie (loc. sup. cit). Testut 

 and Jacob also figure this relation- 

 ship in fig. 164 of the work already 

 alluded to Avhilst Birmingham (6) 

 in fig. 709 shows a very slight 

 groove for the Stylohyoid muscle 

 above. In our own specimens the 

 Styloid and the Stylohyoid and 

 Styloglossus muscles arising from

it, were always in relation to the 

 postero-internal surface immediately behind the internal border. Thus 

 there are three separate areas for muscles on this surface of the gland. 

 In one of our subjects the Digastric bellies were larger than 

 usual and this may have caused us to exaggerate slightly the extent 

 of this impression. Still even with a small muscle the hollowing out 

 is very marked compared with the narrow area often perfectly flat
