ENGLISH  CHLOROFORM  IN  GERMANY. 
By  Dr.  F.  Versmann. 
Many  professors  of  German  laboratories  and  proprietors  of  chemi- 
cal works  have  adopted  the  valuable  plan  of  communicating  to  the 
journals,  from  time  to  time,  observations  and  points  of  practical  ex- 
periences made  in  the  course  of  their  investigations;  and  it  would  be 
well  if  this  plan  was  imitated  here,  as  much  labor  and  trouble  may 
often  be  saved  by  this  liberal  exchange  of  practical  information. 
This  arrangement,  like  everything  good,  is,  however,  not  quite  un- 
alloyed, for  it  sometimes  happens  that  statements  are  published  which 
are  of  little  use,  or  which,  on  examination,  are  found  to  be  incorrect. 
The  last  is  the  case  with  a  communication  in  a  current  number  of 
Buchner's  "  Repertorium  der  Pharmacie,"  and  as  this  special  incor- 
rectness bears  on  an  English  article,  it  may  not  be  out  of  place  to 
rectify  it.  Mr.  E.  Sobering,  in  his  practical  communication,  asserts 
that  abroad  English  chloroform,  sp.  gr.  1485,  is,  for  anaesthetic  pur- 
poses, preferred  to  the  German  (the  Prussian  Pharmacopoeia  prescribes 
a  specific  gravity  of  1500)  because  of  its  greater  stability.
