Adulteration  of  Codliver  Oil.  —  A  Dutch  journal  contains  an 
account  on  codliver  oil  adulterations.  The  oil  is  stated  to  be  frequently 
adulterated  in  Norway  with  the  oil  of  the  liver  of  Scymnus  borealis,  a 
xish  belonging  to  the  shark  family,  found  in  large  numbers  in  the 
Arctic  Ocean,  the  northern  portion  of  the  North  Sea  and  along  the 
west  coast  of  Norway.  The  largest  of  these  fishes  yield  \\  to  2 
casks  of  Hver,  the  oil  of  which  is  fully  as  bright  and  clear  as  codliver  oil, 
contains  little  stearin,  is  cheaper,  almost  equally  as  efficacious,  but  has  a 
rerv  disagreeable  taste.  The  fat  of  the  marine  mammalia  is  also  fre- 
quently used  for  sophistication,  but  rarely  in  Norway.  It  contains 
\  erv  little  fatty  acid,  and  is  with  difficulty  digested. — Ibid.^  Dec.  3,

Production  of  Codliver  Oil  in  Norway  in  1879. — (p^or  produc- 
tion in  1878  see  ^'Amer.  Journ.  Pharm.,"  April,  1879,  p.  194.)  L. 
Monrad  Krohn  reports  that  the  catching  of  codfish  and  the  preparation 
of  the  oil  give  employment  to  a  larger  number  of  fishermen  every 
year;  that  the  total  quantity  of  medicinal  oil  exported  from  Bergen  in 
1879  was  about  3,600  hectoliters  (=3,100  casks)  white  oil  prepared  by 
steam-,  $5,000  hectoliters  (=13,000  casks)  yellow  medicinal  oil,  and 
6,000  hectoliters  (=5,000  casks)  browish-yellow  oil.  The  white  oil  is 
prepared  with  constantly  increasing  care.  The  brownish-yellow  oil  is 
exported  for  medicinal  purposes  principally  to  Belgium  and  Holland. —

Production  of  Iodine  in  Norway, — 150  kilos  of  first-class  iodine, 
the  first  manufactured  at  a  new  laboratory  at  Bergen,  was  recently 
exported  to  Germany.  L.  Monrad  Krohn  expresses  the  opinion  that 
Korway,  with  its  extensive  sea  coasts,  rich  in  laminarian  species,  will 
undoubtedly  soon  produce  an  immense  quantity  of  iodine. — Ibid.
