small  piece  of  potassium  hydrate  is  added  to  a  boiling  solution  of 
benzonaphthol  in  alcohol-free  chloroform.  (2)  An  alcoholic  solu- 
tion of  benzonaphthol  to  which  an  equal  volume  of  nitric  acid  has 
been  added,  must  not  become  cherry  red  in  color  on  addition  of  a 
few  drops  of  acid  mercuric  nitrate  solution. 
/3-Iodonaphthol,  a  New  Aristol. — G.  Braille  (L  Union pharmaceut., 
1 891,  437)  gives  the  following  directions  for  the  preparation  of  this 
body:  A  solution  of  24  gm.  iodine  and  27  gm.  potassium  iodide 
in  water  is  added  to  a  solution  containing  no  gm.  /3-naphthol  and 
40  gm.  potassium  hydrate.  To  this  mixture  is  gradually  added  a 
solution  of  sodium  hypochlorite  containing  10  times  its  volume  of 
combined  chlorine.  /?-iodonaphthol  separates  in  the  form  of  a  green- 
yellow  pulverulent  precipitate,  which  is  washed  several  times  and 
then  dried.  It  is  odorless  and  tasteless,  insoluble  in  water,  partially 
soluble  in  alcohol  and  acetic  acid.  On  exposure  to  light  the  body 
is  quickly  darkened. 
Ferrated  Cod-Liver  Oil. — Bulletin  de  la  Societe  de  Pharmacie, 
Bordeaux,  1891,  341,  gives  the  following  formula  for  this  preparation. 
Cod-liver  oil  2,000  gm.;  alcohol  90  per  cent.,  1,500  gm.  and  caustic 
potash  3,300  gm.,  are  heated  until  saponification  has  taken  place  ; 
then  while  warm  the  mass  is  mixed  with  perchloride  of  iron,  2,700 
.gm.,  in  distilled  water,  5,000  gm.  The  iron  soap  separates  as  a 
brown  mass,  is  washed  with  water  and  then  heated  to  drive  out  the 
water.  Lastly  it  is  dissolved  with  the  aid  of  heat  in  five  times  the 
quantity  of  cod-liver  oil.  The  finished  product,  weighing  2,700 
gm.,  is  set  aside  to  settle  and  is  then  filtered 
Quinethyline  has  been  prepared  by  E.  Grimaux  and  A.  Arnaud 
(Compt.  rend.  112,  1364)  by  heating  in  sealed  tubes  at  95-ido0  C. 
cupreine  dissolved  in  alcohol,  with  sodium  and  ethyl  nitrate.  The 
dry  base  melts  at  1600  C,  is  very  soluble  in  all  ordinary  solvents  for 
alkaloids  and  yields  very  fluorescent  solutions  with  excess  of 
sulphuric  acid.  The  normal  sulphate  crystallizes  in  colorless  efflor- 
escing prisms,  dissolves  in  51  parts  of  water  at  190  C,  and  with 
hydriodic  acid  and  iodine  yields  garnet-red  needles,  unlike  the  plates 
of  herapathite  given  by  quinine.  The  new  base  is  the  ethyl-ether 
of  cupreine,  while  quinine  is  the  corresponding  methyl-ether.  (See 
Amer.  Jour.  Phar.,  1891,  p.  350.)
