BIBLIOGRAPHY 



NOTE: The list of titles which follows is but a tiny portion of the whole 

 literature of the eye. Its items have therefore been selected carefully. I have 

 tried to include the sources of borrowed illustrations, and the more important 

 works of all authors specifically mentioned in the text — in some instances citing 

 only the author's later contributions, the bibliographies of which will provide 

 leads to the earlier work of that author and others. I have included a number 

 of books, compilations, and monographs whose long lists of literature will give 

 the beginner a good start in compiling his own card-catalogue of those phases 

 of the subject which interest him most. Certain of these major works (some of 

 them now obsolete, but definitive in their time) should perhaps be the first to 

 be consulted by the new investigator of the vertebrate eye, and these have been 

 starred (*). The more important of my own papers are also listed, and I have 

 ventured to star a couple of those whose bibliographies contain a number of 

 important references which have been omitted here. 



I have included a few non-ophthalmological items (and where their titles are 

 not self-explanatory, I have annotated them) ; but I have made no attempt to 

 list all of the sources of my zoological and ecological information, for to cite 

 any reasonable number of pertinent works would serve only to give them undue 

 emphasis. Some zoological writings are mines of information; but many a book 

 must be read through for the sake of gaining a single ophthalmological fact. 

 The beginning investigator of the vertebrate eye must read omnivorously in the 

 natural-history field, and is well advised to maintain a correspondence with the 

 curators of the nearest research museum of vertebrate natural history. 



The reader will note that the non-clinical literature of the eye is sadly scat- 

 tered — there have been only two periodicals, both short-lived, which were en- 

 tirely devoted to comparative ophthalmology. These were the Z.eitschrijt fiir 

 vergleichende Augenheilkunde (7 vols., 1882-93) and the Archiv fiir vergleich- 

 ende Ophthalmologic (4 vols., 1910-14). Each of these contains many valuable 

 abstracts as well as original contributions. The student should also make the 

 acquaintance of the Journal of the Optical Society of America, the extinct 

 American Journal of Physiological Optics (7 vols., 1920-6), and the Unter- 

 suchungen aus dem Physiologischen Institut des Universit'dt Heidelberg (4 

 vols., 1877-82). Aside from the latter, which contains practically all of Kiihne's 

 work on rhodopsin, the only general journals which have been heavily com- 

 parative-ophthalmological are the Jenaische ^eitschrift fiir Naturwissenschafi 

 and the Z.eitschrift fiir vergleichende Physiologic. The student simply must 

 keep constant watch for new contributions in all of the morphological, physiol- 

 ogical, and ophthalmological journals. 



Following the list of titles is a list of names, preceded by a separate explan- 

 atory note, which is intended to help the student to locate current literature.
