deners  Dictionary,"  Hudson's  Flora  Anglica,  and  Curtis's  Flora 
Londinensis  take  rank  among  the  classics  of  English  botany,  while 
the  last  named  author's  "  Botanical  Magazine  "  and  Lindley  and 
Moore's  "  Treasury  of  Botany  "  are  standard  works  of  reference  to 
this  day.  These  by  no  means  exhaust  the  list  of  publications  issued 
by  workers  who  were,  at  one  time  or  the  other,  connected  with  the 
Chelsea  Garden — the  list  of  Lindley's  published  works,  for  instance, 
occupies  twelve  pages  of  the  folio  catalogue  of  the  Library  of  the 
British  Museum— but  they  are  the  most  germane  to  our  subject, 
and  comprise  all  that  we  shall  be  able  to  consider  here. 
Dale's  Pharmacologia,  or  to  give  it  its  full  title,  Samuelis  DaleiPhar. 
macologia,  seu  manuductio  ad  Materiam  Medicam:  in  qua  Medicamenta 
Officinalia  Simplicia,  hoc  est  Mineralia,  Vegetabilia,  Animalia  eorumque 
partes  in  Mcdicince  Officinis  usitataf  in  Methodum  naturalem  digest  a 
succincte  &  accurate  describuntur,  was  first  published  in  1693  in  a 
duodecimo  volume,  and  went  through  several  editions  "  both  in  this 
country  and  in  foreign  parts."  The  Tertia  Editio  (fourth  British 
issue)  appeared  in  quarto  in  1737.  Dale's  work  is  written  in  Latin, 
but  an  English  name  is  appended  to  each  substance,  and  an  Index 
Anglo-latinus  in  quo  Nomina  Anglica  Latinis  prceponuntur,  ordine 
alphabetico,  is  added  at  the  end  of  the  book  "  in  gratiam  Tyronum;  " 
in  the  Libet  Secundus,  "  De  Plantis  Medic  amento  sis"  Ray's  system 
is  used  in  toto}    The  great  merit  of  the  Pharmacologia  lies  in  the 
1  Semple  states,  in  his  revision  of  Field's  "  Memoirs  "  (p.  65),  that  the  system 
of  Tournefort  is  adopted  in  the  third  edition-  of  Dale's  Pharmacologia,  but 
this  statement  is  without  foundation.  Pulteney  quite  correctly  says  that  "the 
arrangement  of  the  work  is  that  of  Ray,"  and  Dale  himself,  in  the  preface  to 
his  work,  specifies  his  reasons  for  following  this  course  in  the  following  words: 
"  Praeter  Objectiones  contra  hunc  nostrum  Laborem,  quae  supra  in  hac  Prae- 
fatione  refelluntur,  restant  &  alias  quaedam,  quibus  obviam  ire  hoc  in  loco 
necesse  duxi.  .  .  .  Deinde,  me  stirpes  ad  Raianam  Methodum,  quae  a 
paucis  intelligitur,  disposuisse  dicunt.  Cum  vero  brevitati  semper  consului, 
satius  duxi  methodum  talem  instituere,  qua  singulas  ejusdem  herbae  partes 
simul  tractare  possem,  neque  eadem  saepius  repeterem,  ut  necesse  esset,  si 
veterem  Radicum,  Corticum,  Herbarum,  Seminum,  &c,  methodum,  vel  vires 
medicas  secutus  essem,  uti  ab  aliis  factum  est.  Hoc  quidem  caveri  potuisset,  si 
ordine  Klementari  omnia  distribuissem  ;  tunc  vero  Vegetabilia,  aliaque  con- 
genera  separata  fuissent,  quae  legibus  Physicis  uniuntur ;  &  Lectori  Philo- 
sophico,  tanquam  memoriae  ancilla,  aptius  hae  accommodantur  leges  :  Bt  ut 
verum  fatear,  inter  varias  recentes  Plantarum  methodos  intra  paucos  annos 
editas,  Raianam,  ut  naturae  magis  consentaneam,  caeteris  semper  anteposui."
