should  remain  clear  even  when  10  volumes  of  alcohol  of  the  same 
strength  are  added. 
Determination  of  the  Adulterant  in  Citronella  Oil. — M. 
K.  Bamber  suggests  that  a  mixture  of  2  c.c.  of  pure  cocoanut  oil, 
free  from  acid,  and  2  c.c.  of  oil  of  citronella  be  shaken  for  one 
minute  with  20  c.c.  of  83  per  cent,  alcohol,  in  a  graduated  tube. 
This  container  is  then  centrifugated  for  one-half  to  one  minute. 
The  volume  of  the  remaining  undissolved  oil,  minus  2,  the  amount 
of  cocoanut  oil  used,  indicates  the  impurity.  To  eliminate  any  pos- 
sibility of  error,  a  standard  oil  may  be  compared  with  the  suspected 
sample.    {Phar.  Jour.,  1904,  page  28,  from  Proc.  of  Chem.  Soc.) 
Austrian  Turpentine. — Tschirch  and  Schmidt  {Arch.  d.  Phar., 
I9°3>  Page  583),  report  finding  25  per  cent,  ot  laricopinic  acid. 
This  is  an  amorphous  acid  having  the  formula  C22H30O3 ;  34  per 
cent,  of  laricopinonic  acid,  a  crystalline  substance  having  the  for- 
mula C20H28O4 ;  35  per  cent,  of  essential  oil  having  specific  gravity 
of  0-872  and  boiling  between  154  and  1640  C  ;  2  per  cent,  of  indif- 
ferent resene  and  3  or  4  per  cent,  of  impurities  which  were  not 
determined. 
Bismutose  This  is  a  colloid  bismuth  albuminate,  having  a  yel- 
low color,  and  said  to  contain  21.7  per  cent,  of  metallic  bismuth, 
about  3-3  per  cent,  of  chlorine  and  68  per  cent,  of  albumin,  the  re 
mainder  being  water.  It  is  made,  under  a  German  patent  granted 
to  Kalle  &  Co.,  by  dissolving  242  grams  of  crystallized  bismuth 
nitrate  in  1-200  c.c.  of  a  concentrated  solution  of  common  salt,  and 
then  filtering  the  solution  into  a  solution  of  500  grams  of  pure  egg 
albumen  in  5  liters  of  water.  The  resulting  gelatinous  mass  is  then 
washed  with  hot  water  until  free  from  acid  and  salt ;  it  is  then 
pressed,  dried  and  reduced  to  a  powder.  The  dose  is  from  ro  to 
5-00.    {Chem.  and  Drug. ,  1904,  page  106.) 
Bismuth  Oxyiodo-Agaricinate. — This  bright  grey,  amorphous, 
insoluble  powder  is  an  iodo  compound  of  bismuth  and  agaricinic  acid. 
Like  dermatol,  it  is  intended  to  be  used  as  an  astringent  antiseptic. 
It  is  also  recommended  as  a  remedy  in  the  treatment  of  the  gastric 
and  intestinal  complaints  that  complicate  tuberculosis.  {Phar.  Jour., 
1903,  page  924,  from  Phar.  Zeit) 
Eumydrin-Atropine  Methyl  Nitrate  is  produced  by  the  con- 
version of  the  tertiary  base  of  atropine  into  a  quaternary  base. 
Eumydrin  is  a  white,  odorless,  water-soluble  powder  that  may  be
