confined to one country alone, as I have good reason for knowing; 

 the difficulty of getting at locally and privately printed books is one 

 of the problems of librariaiiship in the present day. 



At no very distant date the literature of Botany will have 

 assumed such portentous dimensions that it will be impossible for 

 any one man to compile its bibliography with any pretence to 

 completeness. Then it will most likely be found necessary to work 

 in combination, each conn try or literary centre contributing its 

 own elaborated quota for final incorporation by one editor. 



My own endeavours to compile some sort of supplement to 

 Pritzel (combined with a selected list of botanical works) can only be 

 considered as suggestive. I was naturally compelled to work in 

 the methods adopted by the Index Society, to the necessary 

 exclusion of fall bibliographical details, but I think I have done 

 enough to show how much remains yet to do. From the Kew 

 library alone I gathered nearly one thousand titles not given in the 

 1 Thesaurus,' a very large proportion being of earlier date than 

 1872. This resulted from systematic comparison of each volume with 

 the ' Thesaurus,' a long, but satisfactory task, and one which Pritzel 

 had not accomplished during his brief visit to this country. Until 

 the printing of my Quids is complete, I cannot be sure of the 

 actual number of "additional works enumerated therein, but I 

 believe that it will amount to more than four thousand. The 

 weakest department in the < Thesaurus,' that of English botanical 

 literature, has of course claimed my earnest attention, and, were 

 it on that account alone, I venture to hope that my compilation 

 Eiay prove useful to the commonwealth of botanists, to whom I 

 dedicate my efforts.
