OBITUARY. 
many  discoveries  connected  with  the  subject  of  light.  He  was  a  promi- 
nent founder  of  the  British  Association,  and  in  1832  was  knighted  by 
William  IY.  One  of  his  last  efforts  was  to  disprove  the  authenticity  of 
the  letters  produced  by  M.  Chasles  to  the  French  Academy,  invalidating 
the  claims  of  Sir  Isaac  Newton  to  the  discovery  of  the  law  of  gravitation. 
Sir  David  retained  his  powers  and  love  of  science  to  the  last,  and,  like 
Faraday,  was  one  of  the  brightest  intellects  in  trie  British  galaxy  of 
scientist. 
William  Herapath,  F.C.S.,  of  Bristol,  England,  died  on  the  13th  oi' 
February,  in  the  73d  year  of  his  age.  He  was  well  known  as  a  toxicologi- 
cal  chemist.  He  discovered  the  curious  compound  iodosulphate  of  qui- 
nia,  which  possesses  optical  properties  like  those  of  tourmaline,  and 
made  its  analysis.  He  was  Professor  of  Chemistry  at  Bristol,  and  one  of 
the  founders  of  the  Chemical  Society. 
Dr.  Daubeny,  of  Oxford,  England,  died  on  the  12th  of  December,  1867, 
at  the  Botanical  Gardens,  in  his  72d  year.  He  was  educated  at  Oxford, 
graduated  in  medicine,  was  elected  to  the  professorship  of  Chemistry  in 
1822,  and  became  a  member  of  the  Royal  Society.  He  afterwards  was  elec- 
ted to  the  professorship  of  Botany,  and  became  Curator  of  the  Botanical 
Gardens,  having  resigned  the  practice  of  the  profession  of  medicine.  He 
wrote  several  works,  among  which  was  a  description  of  volcanoes,  and 
lectures  on  Roman  agriculture.  His  contributions  to  science  were  nu- 
merous and  varied. 
Robert  Warington,  F.R.S.,  died  at  Budleigh,  in  Devon,  on  the  12th 
of  November,  1867,  and  was  born  at  Sheerness,  Sept.  7th,  1807.  He  was 
apprenticed  to  Mr.  T.  Cooper,  a  manufacturing  chemist,  where  he  ac- 
quired his  bent  for  chemical  pursuits;  In  1828  he  was  chosen  by  Prof. 
Edward  Turner  as  his  assistant  for  three  years  ;  he  next  became  the  che- 
mist to  Messrs.  Truman,  Hanbury  and  Buxton,  the  great  brewers,  during 
eight  years,  when,  at  the  death  of  Mr.  Hennell,  he  succeeded  him  as  che- 
mical operator  at  Apothecaries'  Hall,  a  position  he  continued  to  hold  un- 
til a  year  before  his  decease.  Mr.  Warington  took  an  active  interest  in  ' 
matters  connected  with  chemical  science,  and  was  concerned  in  the 
founding  of  the  Chemical  Society,  the  Cavendish  Society,  and  the  Royal 
College  of  Chemistry.  He  was  repeatedly  engaged  as  a  revisor  in  con- 
nection with  the  London  and  British  Pharmacopoeia,  and  in  all  things 
relating  to  the  higher  interests  of  pharmacy  he  was  ever  an  active  and 
useful  observer.  In  natural  history  he  was  particularly  interested  in  the 
investigation  of  the  relations  of  vegetable  and  animal  life,  as  exhibited  in 
those  natural  conditions  represented  by  the  aquarium,  and  published  va- 
rious papers  on  the  subject.  His  papers  are  very  numerous,  and  were 
often  the  practical  applications  of  chemistry  in  the  arts ;  one  of  the  most 
useful  of  them  was  his  discovery  of  the  power  of  animal  charcoal  in  sepa- 
rating bitter  and  other  principles  from  liquids,  noticed  whilst  engaged  at 
the  breweries.    Mr.  Warington  married  in  1835,  and  leaves  a  family.
