consulted  the  collections  at  Kew  for  the  preparation  of  his  work  on 
Cinchonas;  J.  E.  Howard,  the  author  of  classic  monographs  on  the 
genus  Cinchona  ;  Bentley  and  Trimen,  whose  well-known  work  on 
medicinal  plants  contains  numerous  plates  of  plants  figured  from  the 
Royal  Gardens  ;  Sir  George  Watt,  the  author  of  the  "  Dictionary  of 
the  Economic  Products  of  India,"  who  is  at  the  present  time  work- 
ing at  Kew ;  and  last,  but  not  least,  Mr.  E.  M.  Holmes,  the  veteran 
pharmacognosist,  one  of  the  most  indefatigable  investigators  of  the 
riches  of  Kew. 
Kew,  finally,  is  under  constant  requisition  by  manufacturers, 
druggists,  and  drug-brokers,  on  questions  of  economic  botany  which 
affect  their  respective  callings. 
[There  is  no  connected  account  of  Kew  at  present  available,  most  of  the 
literature  on  the  subject  consisting  of  scattered  collections  of  facts  from  which 
it  is  extremely  difficult  to  construct  a  coherent  record.  To  the  student  who  is 
desirous  of  pursuing  the  subject  further,  the  following  list  may  be  of  use,  as  it 
includes  the  most  important  works  on  the  subject  : 
Historical  account  of  Kew  to  1841,  by  the  Director,  in  the  "  Kew  Bulletin  " 
for  December,  1891.    Contains  copious  citations  from  the  earlier  literature.

The  various  hand-lists  of  the  living  collections,  published  at  Kew,  also
