sources  of  the  Society  to  bear  on  his  favorite  subject,  and  to  them  as  the 
unrivalled  teacher  and  writer  on  Materia  Meclica.  His  connection  with  the 
Society  continued  unbroken  till  the  session  1851-52. 
In  1845  Dr.  Pereira  was  elected  a  Fellow  of  the  Royal  College  of  Physi- 
cians, and  almost  immediately  afterwards  became  a  member  of  the  Phar- 
macopoeia Committee,  in  which  position  he  is  believed  to  have  rendered 
important  service,  and  was  curator  to  the  museum  at  his  decease.  On  re- 
signing his  Professorship  at  the  London  Hospital,  in  1850,  he  transferred 
his  most  important  specimens  of  Materia  Medica  to  the  Museum  of  the 
Pharmaceutical  Society,  and  they  are  now  its  property. 
In  descending  a  stair  case  in  the  Ilunterian  Museum,  he  fell  and  rup- 
tured the  rectus  femoris  muscles  of  both  legs,  which  confined  him  to  his 
chamber  for  several  weeks,  but  he  was  able  to  attend  to  his  correspondence, 
and  was  moved  about  on  an  easy  chair,  when,  about  10  o'clock  on  the 
evening  of  January  20th,  he  was  suddenly  carried  off  by  an  internal  injury 
resulting  from  his  fall,  in  the  49th  year  of  his  age,  in  the  prime  of  his  in- 
tellectual power. 
Dr.  Pereira's  mind  was  characterized  by  an  untiring  perseverance  in  the 
pursuit  of  knowledge,  which  would  not  be  satisfied  until  he  had  probed  a 
subject  to  the  bottom.  No  expense  of  time  or  money  was  spared  to  compass 
his  pursuit  of  scientific  truth,  and  in  furtherance  of  his  favorite  study  he 
kept  up  an  extensive  correspondence  with  all  parts  of  the  globe.  His  nu- 
merous papers  in  the  Pharmaceutical  Journal  testify  to  his  industry.  The 
third  edition  of  his  great  work,  though  net  completed,  was  nearly  so,  and 
will  be  brought  out  under  able  superintendence,  and  will  continue  a  lasting 
monument  to  his  science  and  perseverance.
