the nasal side of the eyelid and calls them acino-tubular 

 glands. Yet, both of these authors agree in stating that 

 they found 42 such glands in the upper eyelid, and but 

 slightly differ as to the minimum number in the lower 

 eyelid, while they again agree as regards their maximum 

 number. 



In my description I have, therefore, refrained from using 

 this term for any of the glands which I have found. I may, 

 however, state that the idea of most authors seems to be that 

 the glands which are found in the conjunctiva of the nasal 

 part of the upper eyelid are " Krause's glands." That the 

 number of these glands is very small and never comes near 

 being 42, has been seen from my description. That number 

 can only refer to the palpebral lacrymal glands. 



E. Fuchs * says: " Upon the fornix, especially in its nasal 

 half lie the acinous glands of Krause, while in the temporal 

 half of the tarsus are found lobules similar in character but 

 more densely packed, representing the inferior lacrymal 

 gland." This may, perhaps, sound differently in the origi- 

 nal. Certain it is, that the inferior or palpebral lacrymal 

 gland does not lie in the tarsus. 



On page 560 of the same text-book, Fuchs makes the state- 

 ment (translation) that the inferior lacrymal gland consists 

 of only one or two lobules, for which reason it is also known 

 as the accessory lacrymal gland. 



It does not seem possible that by these two statements he 

 refers to one and the same glandular structure. 



A good description, both of the orbital and of the inferior 

 lacrymal gland, is given by E. Bock in a monograph on the 

 lacrymal gland in health and disease. f 



The best, most extensive and most careful researches and 

 descriptions, and those which most nearly correspond with 

 what I have found, were made by A. Terson, whose excellent 

 monograph t has come to my knowledge and into my posses-
