preparation,  and  the  advantages  they  offer  to  the  medical  prac- 
titioner." 
In  1851,  among  numerous  contributions,  we  have  an  essay  "  On 
the  botanical  and  chemical  character  of  sassy  bark  (the  doom  plant)y 
of  Western  Africa." 
In  1852,  a  continuation  of  the  essay  on  sassy  bark,  and  "  Obser- 
vations on  the  volatility  and  solubility  of  cantharidin,  in  view  of  an 
eligible  pharmaceutical  treatment  of  Spanish  flies." 
In  1853,  fluid  extracts  began  to  attract  attention,  and  in  this  and 
the  succeeding  year  he  contributed  several  papers  on  that  subject ; 
also,  one  "On  the  pharmacy  of  the  phosphates." 
In  1858,  "An  essay  on  the  hypophosphites." 
In  1859,  "  On  polygalic  acid,"  and  "  On  the  existence  of  nicotina 
in  green  tobacco."  In  the  same  year,  he  read  before  the  American 
Pharmaceutical  Association,  in  Boston,  an  elaborate  essay  on  fluid 
extracts,  suggesting  formulae  for  their  preparation,  and  presented 
specimens  of  over  thirty  fluid  extracts  prepared  according  to  his 
suggested  formula. 
For  this  essay  a  copy  of  Pereira's  Materia  Medica  was  voted  to 
him  by  the  Association,  as  a  testimony  of  its  appreciation  of  his  ser- 
vices. This  paper  may  justly  be  considered  as  forming  the  basis  on 
which  many  fluid  extracts  were  admitted  into  the  Pharmacopoeia. 
In  1866,  we  have  an  essay  "  On  Liquidambar  styraciflua  and  its- 
balsamic  resin,"  "showing  the  principle  contained  in  the  resin  to  be 
cinnamic  acid." 
The  papers  contributed  by  Prof.  Procter  to  the  American  Pharma- 
ceutical Association  are  numerous,  and  marked  by  his  usual  careful- 
ness and  accuracy  of  investigation.  Of  these,  his  essay  "On  Ergot  " 
(suggesting  the  use  of  acetic  acid  in  its  preparation),  "  On  aconite 
root,"  "  Atropia  from  American  belladonna,"  "On  extract  of  Can- 
nabis Indica"  "  On  Sassafras  officinale"  may  be  mentioned  as  not 
included  in  the  preceding  review. 
In  the  Proceedings  of  the  Association  for  1873  will  be  found  sev- 
eral able  papers  from  his  pen.  One,  "  On  suggestions  to  beginners 
in  pharmacy,"  should  receive  attention  from  all  of  that  class  who 
purpose  following  in  the  path  which  he  has  trodden  before  them. 
In  concluding  the  memoir  of  Prof.  Procter  there  is  brought  to  our 
minds  one  of  his  last  official  acts  before  this  College :  In  September 
1873,'  as  Chairman  of  the  Committee  on  Deceased  Members,  he  read
