JDIMMOCICS SPECIAL BIBLIOGRAPHIES. 



PUBLISHED IRREGULARLY. 



Nos. 1 and 2 are reprinted on title slips, 12.5X5 cm., in a style similar to 

 that adopted by the Committee on Title Slips, appointed by the American Library 

 Association. (See The Library Journal, 1878, 'V. 3, p. 113-115.) 



The title slips were printed for the lists of Dr. LeConte's and Dr. Horn's papers, 

 bu^ hereafter the lists will be pnt on sale only in pamphlet form. Each reference 

 is independent as heretofore, so .that by cutting out tlie references and pasting 

 them on title slips, one can have the advantages afforded by a title-slip system of 

 bibliography.
