ORIGINAL CONTRIBUTIONS CONCERNING THE 

 GLANDULAR STRUCTURES APPERTAINING TO 

 THE HUMAN EYE AND ITS APPENDAGES.* 



Adolf Alt, M. D. 



PREFACE. 



The studies and investigations which are the subject of this 

 paper are the outcome of a desire to have as clear as possible 

 an understanding of the glandular structures appertaining to 

 the human eye and its appendages from personal knowledge. 



It took a number of years to accumulate the very 

 numerous specimens, the careful study of which furnished 

 the basis for the descriptions here given. While part of the 

 many eyelids which I have examined were obtained from suit- 

 able cases in my own practice, a large number came from the 

 dissecting rooms of the Beaumont Hospital Medical College 

 of this city through the kindness of Dr. R. W. Baker, the 

 demonstrator of anatomy in this institution. Of necessity a 

 great part of this anatomical material was of a pathological 

 character, and it has, therefore, served for other studies as 

 well. 



As it seemed to me that the text-books which I know of, 

 with but few exceptions, deal in a very insufficient manner 

 with this interesting subject, I have thought it might be of 

 some interest to place the results of my own investigations 

 in this direction before the ophthalmic public. This may, 

 perhaps, prove the more interesting, since by the efforts of 

 numerous foreign ophthalmic surgeons, and in this country 

 notably of Dr. C. R. Holmes of Cincinnati t the old operation 

 of the removal of the lacrymal glands for incurable lacryma-
