two  degrees;  in  0  5  to  ro  gm.  doses  it  is  an  excellent  nervine  and 
anti -neuralgic ;  the  daily  dose  of  5-  gms.  gave  relief  in  articular 
rheumatism  after  other  remedies  had  failed.  The  only  objection  to

liability  to  decompose  when  in  solution ;  this  is  noticeable  in 
solution  only  two  days  old. — Apotheker  Ztg.,  1891,  246. 
Benzin. — Numerous  complaints  have  been  made  of  late  regarding 
the  difficulty  in  getting  benzin  which  will  stand  the  test  for  benzol 
(with  nitric  and  sulphuric  acids  no  odor  resembling  oil  of  bitter  almonds 
should  be  noticeable).  L.  Reuter  writing  to  Prof.  Dr.  C.  Engler 
about  the  matter  received  in  reply  "  that  all  crude  oils,  American 
or  Caucasian,  contain  benzol  (the  former  only  in  very  small 
quantity)  and  that  these  oils  carefully  treated  with  sulphuric  acid 
should  be  deprived  of  benzol."  From  another  source  was  gleaned 
that  much  of  the  benzin  of  the  German  market  was  obtained  as  a 
side-product  in  the  manufacture  of  compressed  gas  for  railway 
coaches. — Pharm.  Ztg.,  1 89 1 ,  246  and  270,
