PREFACE 



Bundle." Greek is quoted in the original characters, Latin in 

 italic, or where otherwise it would be doubtful, it is indicated ; this 

 is further explained on the page facing page 1 of the Glossary ; the 

 use of small capitals refers the reader to the word so printed for 

 a definition of the term, or to a correlative term. 



The Appendixes hardly need any detailed explanation; it will 

 be seen that the Bibliography is a selected list of works chiefly 

 in alphabetic form, arranged chronologically. General dictionaries, 

 and large works in which technical terms form only a small pro- 

 portion of the whole, have been omitted. 



The progress of the work through the press has occupied twelve 

 months ; advantage has been taken of this to record new terms 

 which have been published during that time, as well as those con- 

 tributed by friends from obscure sources, some previously rejected, 

 and a few which had been overlooked ; many in the last category 

 are directly due to the defective indexes in certain standard works. 

 No attempt has been made to bring the book beyond the date of 

 1st January 1900, but I have done my best to include all valid 

 terms up to the first day of this year. 



The pleasant task noAV remains of acknowledging most heartily 

 and gratefully the invaluable help I have derived from a host of 

 friends during the progress of the work. Dr D. H. SCOTT, F.R.S., 

 not only encouraged me to undertake the labour, but has always 

 been ready to help with his advice, and has read a part of the 

 proofs ; Mr A. GEPP, of the British Museum, has read the whole 

 in proof and part in revise ; he has spared neither time nor trouble to 

 ascertain the correctness of the derivations and accents throughout, 

 as well as in the special branch of descriptive botany which is under 

 his charge ; Professor HARTOG, D.Sc., of Cork, has had the entire 

 proof through his hands, and has improved many definitions ; 

 Mr H. H. W. PEARSON has read nearly all the slip-proof, sug- 

 gested improvements, and helped in the compilation of the work 

 in many ways. To these four gentlemen I am especially indebted 

 for their kindly undertaking a very troublesome and irksome task. 



Other friends at Kew and the British Museum have also 

 generously aided me in response to questions when drafting the 

 manuscript. Mr G. MASSEE, Mr C. B. CLARKE, F.E.S., and Dr
