PREFACE. 



TT is seldom that in the early attempts to compile a catalogue 

 of the literature of a scientific subject, even of limited range, 

 any high degree of completeness has been attained ; still the 

 present Bibliography owes much to the labour bestowed upon 

 previous works of the same description. 



One of the first authors to compile a list of books and papers 

 relating to the Foraminifera was Ami Boue', who in 1848 pub-

 Nummuliten." This was very creditable to the compiler, for it 

 was more difficult then than now to collect together the scattered 

 notices on any subject. It is to Max Schultze, however, that we 

 owe the first general list, namely, that which appeared in his 

 " Organismus der Polythalamien " in 1854; and within a few 

 years a more extended bibliography was drawn up by W. C.

 Many other compilations have appeared from time to time, no- 

 tably those of J. L. Neugeboren and Th. Marsson, but these for

 geological formations. In 1884, Henry B. Brady published his 

 " Report on the Foraminifera dredged by H.M.S. Challenger?

 has been found exceedingly valuable for reference. The Chal- 

 lenger bibliography, however, was not intended to be exhaustive, 

 and the additions to previous lists consist to a great extent of 

 titles of publications which had found their way into the author's 

 own library. Later, a bibliographic list has been prepared by 

 Anthony Woodward of New York; but this, though supplying
