Hermann  Hager. 
Am.  Jour.  Pharin 
April,  1897. 
1859,  had  commenced  the  publication  of  a  strictly  scientific  periodi- 
cal, the  Pharmaceutische  Centralhalle.  Early  in  i860  he  removed 
to  Berlin,  with  a  view  to  applying  his  entire  time  and  labors  to  sci- 
entific and  literary  work.  Henceforth  his  little  private  laboratory 
became  the  prolific  starting  point  for  the  solution  of  many  a  scien- 
tific or  technical  problem  in  the  practice  of  pharmacy,  and  of  a  vast 
amount  of  analytical  and  microscopical  work.  In  1864  Dr.  Hager 
established,  with  his  friend,  Dr.  E.  Jacobsen,  of  Berlin,  the  Industrie 
Blatter,  in  which  he  inaugurated  a  fearless  exposure  of  the  nostrum 
fraud.  Of  these  specialties  he  analyzed  in  the  course  of  years  more 
than  any  contemporary.  He  provided  his  two  journals  largely  with 
material  from  his  own  pen  and  laboratory  work. 
In  Berlin  Dr.  Hager  contracted  the  friendship  of  the  brothers, 
Ferdinand  and  Fritz  Springer,  of  the  eminent  publishing  firm  of 
Julius  Springer,  who  henceforth  became  his  publishers  and  life-long 
friends.  Here  he  elaborated  and  published  "  First  Lessons  in  the 
Practice  of  Pharmacy,"  "  First  Lessons  in  Pharmaceutical  Botany," 
"  Tne  Microscope,"  "Commentary  on  the  Prussian  Pharmacopoeia," 
"Latin-German  Vocabulary  to  the  Pharmacopoeia,"  and  revised 
some  of  his  former  books  for  republication  in  new  editions.  In 
Berlin  he  also  commenced  the  elaboration  of  his  greatest  and  most 
enduring  work,  the  u  Handbook  of  the  Practice  of  Pharmacy." 
Dr.  Hager's  increasing  reputation  drew  more  and  more  callers  to 
his  quiet  home  and  stud)-  in  the  German  capital.  Being  of  a  retir- 
ing disposition,  and  carefully  estimating  the  value  of  time,  he  gradu- 
ally longed  for  a  refuge  where  he  could  attend  to  and  accomplish  his 
life  work  in  less  disturbed  solitude.  He  acquired  a  modest  farmer's 
home,  located  in  a  rather  isolated  and  unattractive  place,  called  Pul- 
vermiihle,  near  the  village  of  Fiirstenberg,  a  few  miles  distant  from 
the  old  university  city  of  Frankfort,  on  the  Oder  River.  He  re- 
moved thither  in  October,  187 1.  Here  Dr.  Hager  enjoyed,  for  ten 
years  in  full  retirement,  a  studious  and  active  life,  applying  all  his 
time  and  interests  to  research  and  literary  work.  During  these 
busy  years  he  continued  his  analytical  work,  edited  his  two  journals, 
one  in  Berlin,  the  other  in  Dresden,  translated  the  first  Pharmaco- 
poeia of  the  newly  consolidated  German  Empire,  and  in  1872  and 
1873  wrote  a  comprehensive  commentary  on  this  work. 
In  1876  he  completed  and  published  his  "  Handbook  of  the  Prac- 
tice of  Pharmacy,"  in  two  large  volumes,  to  which  he  added  a  third
