THE LACHRYMAL GLANDS. 267 



Pflueger discovered, and to which, in the submaxillaries, he 

 has o^iven the name of salivary canals (Speichelrohren). These 

 are clothed with cylinder epithelium, and must by no means 

 be mistaken for the excretory ducts of the salivary glands, 

 which are covered with pavement epithelium. They ajjpear 

 to me to be forms of a very high functional importance, 

 because in the submaxillaries of the rabbit, where, after treat- 

 ment with 1 per cent, hyperosmic acid, they come out 

 beautifully, they take up a fourth of the volume of the 

 whole gland. That they do not act only as a conducting 

 apparatus, that is, as passages for the secreted saliva, is seen 

 from the fact that some end blindly. By the above-mentioned 

 method one can see very plainly, at the end of the cylinder 

 epithelium, when it is turned to the light, a striping, which 

 might be the indication of a fine system of fibres, or fibrilla- 

 tion. " Lachrymal canals " also appear in the lachrymal 

 glands of the animals examined, but by no means in such 

 numbers as the canals in the submaxillaries of the rabbit.
