best.  A  comparison  of  this  edition  with  the  previous  one,  and  especially 
with  the  older  editions,  will  exhibit  marked  changes,  and  many  improve- 
ments. Obsolete  or  disused  formulae  have  been  omitted,  and  many  new 
recipes,  from  printed  or  private  sources,  introduced,  the  nomenclature 
corrected  to  correspond  with  the  new  Pharmacopoeia,  and  the  table  of  doses, 
first  introduced  by  Dr.  Thomas,  carefully  revised. 
Obituary. 
Prof.  Eilhard  Mitscherlich. — Prof.  Mitscherlich  has  recently  died  at 
Berlin  at  the  age  of  sixty-nine.  He  had  long  been  known  as  one  of  the 
ablest  philosophical  chemists  of  the  day,  and  the  estimation  in  which  he 
was  held  was  exemplified  by  the  numbers  who  attended  his  classes  in  the 
University  of  Berlin,  and  the  Friedrich-Wilhelm's-Institut  in  that  city. 
The  mere  titles  of  his  writings  would  occupy  nearly  two  columns  of  this 
journal ;  they  embrace  a  wide  range  in  chemical  science,  and  may  be  found 
in  the  publications  of  the  Academy  of  Sciences  of  Berlin,  of  which  he  was 
a  member,  and  in  German  periodicals.  Besides  these,  he  was  the  author 
of  a  le  Lehrbuch  der  Chemie,"  in  two  volumes,  which  has  passed  through 
two  editions,  and  has  been  translated  into  French.  Dr.  Mitscherlich  was 
elected  a  Foreign  Member  of  the  Royal  Society  in  1828  ;  and  in  1829  one 
of  the  Royal  Medals  was  awarded  to  him  for  his  "  Discoveries  relating  to 
the  Laws  of  Crystallization  and  the  Properties  of  Crystals."  It  is,  perhaps, 
by  his  researches  into  the  phenomena  of  dimorphism  that  he  will  be  best 
remembered, — Am.  Jour.  Science  and  Arts,  Nov.,  1863,  from  Athenceum,

Prof.  Theodor  W.  C.  Martius. — We  have  to  announce  with  regret  the 
death  of  this  amiable  and  well-known  man  of  science,  which  took  place, 
after  a  long  and  suffering  illness,  on  the  15th  September.  Dr.  Martius 
held  for  many  years  the  Professorship  of  Pharmacy  and  Pharmacognosy 
in  the  University  of  Erlangen ;  he  was  a  Knight  of  the  Royal  Prussian 
Order  of  the  Red  Eagle,  and  member  of  many  scientific  societies,  including 
the  Pharmaceutical  Society  of  Great  Britain,  to  whose  Museum  and  Jour- 
nal he  frequently  contributed  London  Pharm.  Jour.,  Oct.  1863.
