into their places as they arrived and now completely overshadow 

 the original list, into which they were incorporated without dis- 

 turbance of the arrangement. And my complete bibliographic 

 list on any subject is together, so that if I wish to assemble all of 

 my available titles on, say the facial nerve, instead of searching 

 through many volumes of periodically published lists, I simply 

 pick out the cards between two guides and the whole list is before 

 me. The same series of cards may also be used as a catalogue of 

 one's own library without disturbing their position in the file. By 

 marking one of the upper corners of every card which bears a 

 title which is represented in the library with a colored wafer or a 

 rubber stamp, inspection of the card instantly tells whether the 

 article is in the library and the shelf number may be added, if 

 necessary. 



The Concilium, as is well know^n, is not a commercial enter- 

 prise; nor is it necessarily a rival of the variousotherbibliographies 

 now serving the scientific public. The monthly and annual lists 

 are valuable in their way, but in our opinion cannot replace the 

 •card catalogue. And now that the anatomical bibliography of 

 the Concilium has been thoroughly established and enlarged, we 

 bespeak for it the hearty support of anatomical laboratories and 

 libraries and remind our readers that standing orders for all cards 

 on individual topics can be placed. For instance, the neurological 

 cards alone will be sent independently of the rest of the bibliog- 

 raphy. But the cost of the whole anatomical bibliography is at 

 present (author and subject catalogue) only about nine dollars 

 per year. 



This revision diff^ers from the original anatomical classification 

 chiefly by the addition of more subdivisions of the leading topics, 

 thus in no way disturbing the placing of the old cards. There are 

 only two places where the old numbers are changed. The first 

 is a transposition to secure a more logical position of the general 

 introductory divisions. In this case the original numbers occupied 

 by these subjects are left vacant, so that confusion is not likely 

 to occur. The second change involves the substitution in the 

 neurological bibliography for two relatively unimportant entries 

 of a division for Tectonics (including the course of fibers and gray 

 substance) and a division for Localizations. But few old cards 

 are involved in this change and these the Concilium has decided
