Conium  leaves  contained  only  0'24  per  cent,  of  matter  precipitated 
by  Mayer's  reagent. — R.  Kordes,  Pharm.  Ztschr.  f.  Bussl.,  1888,  455. 
Narceine  has  been  carefully  studied  by  Claus  and  Meixner  {Journ. 
Praht.  Chem.)  and  a  close  relationship  to  naphthalin  disclosed.  By  oxi- 
dation of  pure  narceine  CggHsgNOg,  with  permanganate  in  dilute  sul- 
phuric acid  solution  a  tribasic  acid  narceinic  acid,  CigHi^NOg-f  BHgO, 
was  gotten  which  on  heating  to  180°-200°  decomposed  into  carbonic 
oxide,  dimethylamine  and  dioxynaphthalic  acid  Ci2H80g. — Pdsch.,

Secale  cornutum  in  drying  should  be  placed  in  thin  layers,  the  last 
portions  of  moisture  being  removed  over  lime  or  sulphuric  acid  in  a 
dessicator.  Stored  in  corked  yellow  bottles  so-dried  ergot  will  keep 
for  several  years  and  be  of  superior  quality. — F.  Alpers  {Pharm.  Ztg.)

TJnguentum  boroglycerinatum,  a  substitute  for  iodoform  and  carbolic 
acid  ointments  and  a  superior  preparation  of  boric  acid,  is  made  by 
taking  of  boric  acid,  10  parts,  and  glycerin  (sp.  gr.  1*23),  30  parts,  boil- 
ing for  10  minutes;  after  cooling  to  50°  make  an  ointment  by  addition 
of  lanolin  40  parts,  finally  add  paraffin  ointment  (sp.  gr.  0.890)  20  parts. 
This  last  addition  has  the  effect  of  diminishing  the  rapid  absorption  of 
lanolin.  In  appearance  the  ointment  resembles  cold-cream. — Koehler^

Liquor  Jerri  dialysati  and  oxyohloridi. — M.  C.  Traub  finds  that 
there  are  decided  differences  in  the  properties  of  these  two  preparations, 
and  disapproves  of  the  substitution  of  the  latter  for  the  former.  The 
oxychloride  solution  is  made  by  dissolving  ferric  hydrate  in  hydro- 
chloric acid ;  it  contains  0*8  per  cent.  HCl,  is  of  a  decided  acid  taste 
and  reaction,  and  is  not  adapted  for  making  the  albuminate  solution 
owing  to  its  frequent  gelatinization.  The  dialyzed  solution  contains 
only  0'25  per  cent.  HCl,  is  of  a  mild  taste  and  neutral  reaction,  and 
will  form  a  permanent  albuminate  solution. — Schwz.  Wchnschr.  f.

Carbon  disulphide  in  oil  of  mustard. — The  first  detection  of  carbon 
disulphide  in  the  volatile  oil  of  mustard  was  attributed  to  adulteration, 
but  the  statement  of  the  producer  that  his  oil  was  made  from  the  seeds^ 
of  Sinapis  juncea  caused  new  experiments  to  be  made  as  the  result  of 
which  Hoffmann  established  the  presence  of  carbon  disulphide  in  the 
oil  of  Sinapis  juncea,  as  well  as  in  the  oil  of  Brassica  nigra  and  the 
artificially  prepared  oil.    Paul  Birkenwald  uses  the  following  mode
