Cole, Bibliography of the Ichihyopsida. 217 



Several works will be included which are not concerned 

 directly with the Ichthyopsida, but with the results of which 

 it is important that a worker in the group should be acquainted. 



At present, as the result of three year's vacation work, 

 some 800 works have been seen and recorded, and about 200 

 of these have been worked through and indexed. It seems 

 very likely that the complete bibliography will contain 1600 

 references, so that its completion without more leisure will take 

 some time. It is hoped to include works up to the end of the 

 century (by which I mean to the end of the current year). 



The length of the list in a bibliography so circumscribed 

 is such that it seems imperative to halt before pursuing any 

 further the paths of research, and to consider what has already 

 been effected. It is safe to say that much of the work now 

 being done has been done before and often done well, and if 

 the bibliography, even only in some measure, helps us to real- 

 ize where we are, it will have been well worth doing. Let us, 

 therefore, keep in mind the fate of the men who started out 

 to build a tower to heaven, and finished by perpetuating a babel 

 upon earth.
