Bibliographies of Botany, 333 



method of Dry an der, as regards the treatment of periodicals in a 

 bibliographical record. We stand in great need of normal collations 

 for botanical — and other — serial publications. The collation of a 

 set of Botanisches Centralblatt often falls to the share of librarians 

 and booksellers, and certain volumes present difficulties that make a 

 normal collation, based upon a careful comparative study of various 

 sets, highly desirable. How, indeed, would it be possible to verify 

 a set of Philosophical Transactions previous to 1800 if it were not 

 for the detailed collation given byDryander in the first volume 

 of the Banks Catalogue? Junk's collation of the Regensburger Flora 

 is work of the same quality. Pritzel's enduring fame rests upon 

 the same thing.
