BIBLIOGRAPHY. 



Tho following l^ihlio^M'apliy is inU^iidrd i<. (over only llic urlicles cited in th<.^ accom- 

 panying i)upcr. In the litLTattao of tlie diatoms a large proportion of the citations 

 are to scparatea and an altL*m])t has l)een made to corrohitc these with the publication 

 in whu'h they were originally isMied, citing oidy the hitter in a uniformly abbreviated 

 siyle. For the convenience of t^tu(hmts references as full as at present practicable 

 are inserted undt^r each title to the libraries in Washington containing the work. 

 These libraries, however, have not been thorouglily searched for diatom literature 

 and it is probable that many of the works may be found in other of the libraries than 

 those indicated. Iji cas(^ of a single work reference has been made to the library of 

 Korthwesteru ITniversity, Kvanstou, 111., where it is known to exist complete. The 

 abbreviations, as fai* as they concern "Washington libraries, are based on those used 

 in A Union List of Periodicals, Transactions, and Allied Publications in the T.ibrarii^s 

 of the District of Coluinl>ia, pul)lished by the Library of Congress in 190L The abbre- 

 viations are as follows:
