degree  and  an  itistructorship  in  1864.  In  1866  he  was  elected  Professor  of 
Materia  Medica  of  the  Paris  School,  a  position  which  he  retained  to  his  death. 
Planchon  was  a  brilliant  teacher, an  able  manager  and  an  indefatigable  worker. 
His  contributions  to  science  were  numerous  and  valuable,  while  his  two  books, 
""Trait  Practique  de  la  Determination  des  Drogues  Simples,"  1875,  and 
*'  Drogues  Simples  d'Origine  Vegetale,"  1895,  are  classics  of  pharmacy. 
His  last  appearance  was  at  the  grave  of  his  colleague,  Professor  Beauregard, 
where  he,  despite  an  attack  of  grippe,  pronounced  the  eulogy.  Immediately 
thereafter  he  sought  recuperation  at  his  old  home,  Montpellier,  where  he  died 
April  16th. 
H.  BEAUREGARD. 
H.  Beauregard,  a  pupil  of  Planchon,  was  born  in  Havre  in  1855.  He  studied 
at  Paris  science,  medicine  and  pharmacy,  his  high  scholastic  record  winning 
for  him  successively  the  positions  of  hospital  interne,  preparateur  in  natural 
sciences,  laboratory  instructor  in  chemistry  and  quiz-master  in  the  natural 
sciences.  In  1885  he  added  to  his  other  duties  that  of  naturalist  in  the  labora- 
tory of  comparative  anatomy,  at  the  same  time  making  investigations  which 
brought  him  much  distinction.  Of  special  pharmaceutical  interest  was  his 
work  on  spermaceti,  ambergris  and  cantharidin.  In  1898  he  was  given  the 
chair  of  cryptogamic  botany  in  the  School  of  Pharmacy,  and  a  most  striking 
proof  of  his  versatility  was  shown  in  the  able  manner  in  which  he  taught  this 
branch,  in  which  he  had  scarcely  specialized.  Two  short  years  was  he  permitted 
to  enjoy  the  highest  fruits  of  his  labor,  for,  on  March  30th,  he  was  called  upon 
to  lay  his  burden  down. 
A.  MILNE-EDWARDS. 
Alphonse  Milne-Edwards,  Professor  of  Zoology  and  Director  of  the  Museum 
of  Natural  History,  Paris  School  of  Pharmacy,  died  April  21st.  Reared  among 
the  rich  collections  of  the  Museum  of  Natural  History,  his  entire  career  was 
devoted  to  the  Paris  School,  to  which  he  was  called  as  professor  in  1865,  when 
scarcely  thirty  years  old. 
To  him  his  science  was  his  life,  and  recital  of  his  achievements  is  at  once  the 
inspiration  and  the  despair  of  his  less  gifted  followers. 
On  submarine  fauna  he  was  unexcelled.  Beside  proving  that  animal  life 
existed  1,200  fathoms  beneath  the  surface  of  the  sea  (i860),  he  organized  two 
scientific  dredging  explorations,  under  the  auspices  of  the  French  Government, 
winning  by  his  efforts  the  gold  medal  of  the  Geographic  Society. 
In  1869  he  published  a  work  on  the  fauna  of  the  southern  hemisphere,  which 
has  become  a  classic,  it  being  given  that  high  distinction,  "  couronne  par 
1'Academie."  He  next  turned  to  paleontolog)',  the  fossil  crustaceae  being  his 
first  subject,  and  then  the  osteology  of  prehistoric  birds,  the  latter  work 
(1869-1871)  bringing  for  him  the  grand  prize  of  the  Academy  of  Sciences.  In 
his  later  years  he  studied  the  fauna  of  Madagascar.  H.  V.  Arny. 
Chlorinated  Lime. — The  amount  of  chlorine  in  Calx  chlorata  is  deter- 
mined by  Wolanski  {Ann.  de  Chim.  Anal.,  1900,  p.  235),  as  follows  :  The  solu- 
tion of  Calx  chlorata  (about  1  per  cent.)  is  poured  into  5  c.c.  of  a  potassium 
iodide  solution  (o*i  per  cent.)  acidified  with  H2SOi.  The  iodine  combines  with 
the  chlorine,  forming  IC15,  and  the  solution  becomes  decolorized.
