 says, to the anus). It lines the excretory ducts of all glands; the

It is also ciliated in all the following parts the finest bronchial 



tubes, and all the sinuses (frontal 

 and maxillary), and the cells

 Peculiarities. The fact that 

 this kind of epithelium lines the uterine glands, is an exception to 

 the law before stated, that the ultimate follicles of all glands are 

 lined by simple scaly epithelium. (Kolliker.)
