SALIVARY GLANDS OF LOWER PRIMATES 



the presence of the nerve in this situation had produced an interruption 

 of an originally continuous glandiferous line, dividing the same into the 

 lesser sublingual group proper (j) and the isthmian elements (j'). This 

 impression is strengthened by the few instances in which the two groups 

 were actually continuous with each other and only somewhat thinned 

 and reduced in number at their point of intersection with the Ungual 

 nerve. There seems httle doubt that the human structure described

as the gland of Weber is notliing more than one of the first isthmian 

 elements, encountered just caudal to the lingual nerve and separated 

 by the same from the lesser sublingual group proper. 



At the other extremity the isthmian series approaches, and in some 

 instances (Lemurs) merges with, the gland mass of the soft palate. 



It is necessary to state clearly in this connection that the above 

 outhned relation of the lingual nerve to the lesser subhngual group of 

 glands is a condition peculiar to primates, which does not obtain in the
