tubular type (Marziarski *) (Fig. 174, page 192), and consists of 

 eight to twelve small lobules which open into the fornix conjunc- 

 tivae by about as many minute ducts.. The lobules are united by 

 thin fibrous fasciae which contain the larger ducts. 



Each lobule of the gland contains many serous secreting acini 

 and numerous small intralobular ducts. The secreting acini are

lined by tall, columnar cells, resting upon a thin basement mem- 

 brane, which is supplied with basket cells (Korlzelleri) and is 

 invested with a delicate fibrous tunica propria. The appearance 

 of the secreting epithelium differs somewhat according to its state 

 of activity. After a period of rest, and in the ordinary condition 

 of relative inactivity, the epithelium becomes distended with secre- 

 tion and is either clear in appearance or at most is only very finely 

 granular, the nuclei are crowded to the base of the swollen cells,
