Between the well-developed intercalated duct and the intralobular duct, the granular tubule is

in the intercalary and intralobular ducts differs considerably (Fig. 

 2.4). It is natural that many authors from Merkel onward should 

 have attempted to correlate the histological pattern with the com- 

 position of the saliva secreted by the gland (Babkin, 1944; Thay-
