William  Procter,  Jr. 
Am.  Jour.  Pharm. 
June,  1900. 
In  1842,  "Observations  on  the  Volatile  Oil  of  Gaultheria  Pro- 
cumbens,  Proving  it  to  be  a  Hydracid  Analogous  to  Salicylous  Acid." 
A  year  later,  M.  August  Cahours  took  up  the  same  subject,  and 
arrived  at  the  same  results  by  a  proximate  analysis  of  the  oil,  but 
in  his  paper,  published  in  the  Journal  de  Pharmacie  ct  de  Chimie, 
March,  1843,  he  makes  no  allusion  to  Mr.  Procter's  previous  publi- 
cation, leaving  us  uncertain  whether  he  had  seen  Mr.  Procter's 
paper,  or  whether  the  investigation  made  by  him  was  coincident 
with  that  of  Mr.  Procter. 
In  1843,  "  On  the  Volatile  Oil  of  Betula  Lenta  (Sweet  Brier)  and 
on  Gaultherin,"  a  substance  playing  a  part  similar  to  amygdalin, 
and  which,  by  its  decomposition,  yields  an  oil  identical  with  oil  of 
gaultheria. 
In  1847,  "  On  the  Reduction  of  Oxide  of  Iron  by  Hydrogen." 
In  1849,  "Remarks  on  the  Oleo-resinous  Ethereal  Extracts,  their 
Preparation  and  the  Advantages  they  Offer  to  the  Medical  Practi- 
tioner." 
In  1851,  among  numerous  contributions,  we  have  an  essay  "  On 
the  Botanical  and  Chemical  Character  of  Sassy  Bark  (the  Doom 
Plant)  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  Nico- 
tina  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  pre- 
sented 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 
services.  This  paper  may  justly  be  considered  as  forming  the  basis 
on  which  many  fluid  extracts  were  admitted  into  the  Pharmaco- 
poeia. 
In  1866,  we  have  an  essay  "  On  Liquidambar  Styraciflua  and  its
