students  who  wish  to  follow  the  art.  This  grand  idea  that  laid  dor- 
mant more  than  fifty  years  till  the  man  arrived,  is  a  counterpart  of 
the  old  professional  pharmacy  of  1 50  years  ago. 
In  one  pane  the  Pharmacie  Centrale  displays  some  pharmaceuti- 
cals, such  as  pills,  perloids,  minute  seed-like  pills  of  red  and  white 
tints,  troches  and  other  fine  goods.  In  the  second  pane  are  their 
alkaloidal  manufactures  such  as  beautiful  white  silky  quinine  hydro- 
bromate  and  hydrochlorate.  Quinine  dibromhydrate  in  heavy 
crusts,  digitaline  crystallized,  in  fact,  a  very  nice  display  of  alka- 
loidals  of  all  kinds. 
ALFRED  H.  ALLEN. 
By  Samuel  P.  Sadtxer. 
Alfred  Henry  Allen,  F.C.S.,  well  known  to  all  chemists  by  his 
monumental  work  on  "  Commercial  Organic  Analysis,"  died  July 
14th,  after  an  illness  that  appeared  already  ten  years  ago,  and 
which  he  fought  during  that  time,  knowing  that  the  malady  in  the  end 
would  conquer.  Moreover,  these  ten  years  were  among  his  most 
active;  paper  followed  paper,  volume  followed  volume,  the  work 
being  broken  only  occasionally  by  journeys  for  his  health  to  the 
South. 
Allen  began  his  career  as  a  food  analyst  by  serving  as  assistant 
to  the  late  Dr.  A.  H.  Hassall,  well  known  by  his  work  on  "  Foods 
and  Their  Analysis,"  and  already  in  1873  he  was  appointed  as  Pub- 
lic Analyst  to  the  Corporation  of  Sheffield,  and  continued  here  in 
active  practice  until  his  death. 
The  Society  of  Public  Analysts  was  founded  by  him  in  1874,  and 
whether  as  its  President  or  on  the  Publication  Committee  of  the 
Analyst,  he  was  active  in  its  service  the  remainder  of  his  life. 
He  was  one  of  the  original  members  of  the  Society  of  Chemical 
Industry,  founded  in  188 1,  and  active  on  its  Publication  Committee 
also  until  his  death. 
His  great  work,  however,  and  by  which  he  will  always  be 
most  gratefully  remembered  by  working  chemists,  was  his  "  Com- 
mercial Organic  Analysis,"  begun  in  1879  and  continued,  volume 
for  volume,  through  three  editions  down  to  the  time  of  his  death. 
This  great  work  is  an  encyclopaedia  of  working  methods  of  proxi-
