* Tho above list simply oontains those papers consulted by the author in writing the present work. A complete 

 Bibliography of the anatomical, enibryological, physiological, recent and fossil literature, directly or indirectly treating 

 of the Brain, Cranial Nerves, and Lateral Sense Organs of Fishes and Amphibia, is iu active preparation, and will be 

 publislied separately. Nevertheless, although the present list has already been more than doubled, the author would 

 be extremely grateful for any references not included in it, either to the sender's own papers, or to any others which 

 should have been recorded. The objects of the forthcoming Bibliography (by no moans a mere list) are : (1) to 

 provide an absolutely complete and accurate catalogue of all the works ever published more or less relating to the 

 subject; (2) to be a guide to an author (by means of abstracts, indexing, &c.) newly taking up the subject to the 

 literature immediately affecting his sjtecial purpose, and also to those general works it were expedient that he should 

 consult ; (3) to supply the pressing need of an Index Expur(jatorius, With regard to the latter, and perhaps most 

 important, object, it is obvious that an author, however conscientious, cannot be expected (unless, indeed, he is 

 writing an extensive monograph) to wade through at least 700 papers before writing his own. It is equally obvious 

 that many of these papers, either on account of the antiquity of their contents, or other equally potent but less 

 excusable reasons, may very well be consigned to the " silent tomb," and piously allowed to remain there. The want 

 of such an analytical Bibliography has, even in the confined experience of the author, over and over again imjjaired 

 an otherwise useful piece of work. It is respectfully hoped, tliercfore, that a diligent and unprejudiced search 

 through the literature will have the general effect of clearing the air, and thus proving of some service to those 

 subsequently taking up the work.
