law  for  Illinois,  and  after  the  passage  of  the  law  in  1881  became  the  first  presi- 
dent of  the  State  Board  of  Pharmacy.  The  deceased  was  highly  esteemed  for 
his  competency  as  a  pharmacist,  his  sterling  integrity  as  a  business  man,  and 
his  moral  worth  as  a  citizen. 
Professor  Adolf  Ferdinand  Dujlos  died  in  Annaberg,  Saxony,  October  9th , 
in  his  88th  year.  He  was  born  at  Artenay,  near  Orleans,  February  2, 1802,  his 
father  being  a  soldier  in  the  French  army.  Having  lost  by  death  both  his 
parents,  his  uncle,  a  surgeon  in  the  French  Army,  took  charge  of  the  boy,  and 
during  the  campaign  of  1813  placed  him  in  charge  of  Dr.  Benedict,  rector  of 
the  lyceum  at  Torgau,  with  whom  he  remained,  an  orphan  without  known 
relatives,  after  the  uncle's  death.  In  1815  he  entered  a  pharmacy  at  Annaberg 
as  apprentice,  remained  here  six  years,  and  then  became  assistant  in  a  phar- 
macy at  Breslau  where  also  chemicals  were  manufactured  on  a  rather  exten- 
sive scale.  While  here  he  wrote  his  first  scientific  essay  "  on  the  theory  of  the 
formation  Qf  ether,"  of  which  an  abstract  was  published  in  Buchner's  Reper- 
torium  (1824)  xviii,  p.  245,  where  it  is  credited  to  X.  J.,  vi,  1,  305  (probably 
Trommsdorff  s  Neues  Journal  der  Pharmacie,  vi  [1822]  ).  After  acting  for  three 
years  as  assistant  to  the  pharmaceutic  institute  at  the  university  of  Halle,  he 
returned  to  Breslau  in  1833,  teaching  chemistry  at  the  classsical  school  (gym- 
nasium), and  in  1843  becoming  administrator  of  the  University  pharmacy,  in 
which  position  he  founded  the  pharmaceutic  institute  of  the  University  of 
Breslau  which  he  conducted  until  1866,  when  the  failing  of  his  eyesight  com- 
pelled him  to  resign.  The  university,  in  recognition  of  his  valuable  services, 
conferred  upon  him,  honoris  causa,  the  titles  of  doctor  of  philosophy  in  1841, 
and  doctor  of  medicine  in  1861. 
The  literary  labors  of  Duflos  have  been  very  extensive,  and  were,  in  part, 
made  public  through  numerous  essays,  published  in  various  journals,  on  sub- 
jects connected  with  pharmaceutical,  analytical  and  technical  chemistry.  Among 
his  larger  works  may  be  mentioned  the  following :  Pharmaceutico-chemical 
Practice  ;  Articles  of  Food  and  their  Adulterations ;  Agricultural  Chemistry; 
Economic  Chemistry  (jointly  with  A.  G.  Hirsch);  Pharmacological  Chemistry; 
Detection  of  Poisons;  Examination  of  Chemical  Remedies,  and  Chemisches 
Apotheker-Buch  (Chemical  Book  for  the  Apothecary).  The  last-mentioned 
work,  of  which  the  sixth  edition  appeared  in  1880,  was  for  many  years  regarded 
as  the  best  and  most  practical  work  in  the  German  language  for  the  study  of 
pharmaceutical  chemistry  and  for  use  in  the  laboratory  of  the  pharmacist. 
When  he  vacated  his  academic  chair,  Duflos  retired  to  Annaberg,  where  he 
was  first  initiated  into  the  art  and  science  of  pharmacy,  and  lived  with  the 
descendants  of  his  foster-parents  until  his  death.  As  long  as  his  eyesight  per- 
mitted he  continued  his  researches  and  literary  work  ;  and  when  he  was  no 
longer  able  to  read,  his  younger  friends  read  to  him  the  journals  published  in 
the  interest  of  pharmacy. 
Rather  few  of  Duflos'  papers  found  their  way  into  the  journals  of  this 
Country ;  but  many  American  pharmacists  were  familiar  with  his  writings,  and 
the  American  Pharmaceutical  Association  had  placed  his  name  on  the. roll  of 
honorary  membership.
