The gland is devoid of inter- acinar ducts: the tubules of the 

 many-layered type of acinus ultimately uniting to form the duct which 

 conveys the secretion to the urethra. This duct I have found in some 

 instances to maintain a many-layered character right into the urethra ; 

 but at other times the rows were fewer and the individual cells flattened. 

 The method of termination 

 of the duct in the urethra ,..;,':. 



is represented by a camera- 

 lucida drawing in Fig. 5. 

 The animal from which the 

 drawing was made was 

 sexually active.
