cent,  of  the  sulphur  chloride  should  be  used  to  obtain  a  glue-like  non- 
pulverizable  mass,  which  will  retain  70  per  cent,  of  carbonbisulphide  ; 
but  by  increasing  the  chloride  the  mass  will  assume  the  aspect  of  horn 
and  be  so  friable  as  to  be  easily  reduced  to  powder  by  rubbing  between 
the  fingers,  while  at  the  same  time  the  largest  portion  of  the  volatile 
liquid  is  given  off.  Boiled  linseed  oil  is  best  adapted  for  these  pur- 
poses.— Rep.  de  Phar.,  May  15,  p.  294. 
Glycerite  of  Phosphorus. — Chas.  Meniere  recommends  to  mix 
some  sugar  or  gum  arabic  with  sufficient  glycerin  to  obtain  a  mixture 
of  the  consistence  of  honey  ;  this  is  heated  to  43°C  (no°F.),  when 
O'lO  gram  phosphorus  is  dropped  in  and  finely  divided  with  the  aid 
of  a  pestle.  Enough  glycerin  to  make  1,000  grams  is  then  added 
in  small  quantities,  the  heat  of  the  water  bath  being  kept  at  about  500 
C.(i22°F.);  the  turbid  mixture  gradually  becomes  clear,  is  then  set 
aside  for  24  hours,  filtered  and  bottled. — Ibid.,  June  25,  p.  354. 
Solubility  of  Sulphur  in  Acetic  Acid. — Leo  Liebermann  has  ob- 
served that  concentrated  or  somewhat  diluted  acetic  acid  will  dissolve 
appreciable  quantities  of  sulphur,  which  are  separated  again  as  a  milky 
precipitate  on  the  addition  of  water,  or  in  the  form  of  long  prisms  if 
evaporated  under  an  air  pump. — Ber.  Chem.  Ges.,  1877,  p.  866. 
Products  of  the  Distillation  of  Wood  at  a  low  Temperature. 
— On  the  dry  distillation  of  wood  at  a  temperature  below  200°C.  a  pro- 
duct is  obtained,  which  on  rectification  yields  a  heavy  oil,  but  slightly  sol- 
uble in  water.  H.  B.  Heill  obtained  a  quantity  of  this  oil  from  Dr.  Squibb 
and  found  it  to  contain  furfurol,  a  yellow  body  yielding  pyroxanthin  on 
being  treated  with  caustic  soda,  some  pyromucic  acid,  an  oil  having  the 
odor  of  smoked  fishes,  and  other  products  not  yet  examined,  Ibid.,  p.

Aeterpen  (see  "Am.  Jour.  Phar.,"  1876,  p.  411),  discovered  by 
Meyer  and  Spitzer,  has  not  the  composition  C12H20,  as  previously  an- 
nounced, but  is  C10H16. — Ibid.,  p.  990  and  1034. 
Liquor  ferri  acetici,  Ph.  Germ.,  is  prepared  by  precipitating  with 
ammonia  10  parts  of  solution  of  ferric  sulphate,  sp.  gr.  1*318.  The 
washing  and  expression  of  this  precipitate  is  a  very  tedious  operation; 
G.  Mankiewicz  therefore  recommends  to  collect  it  upon  a  strainer  and 
expose  it  to  a  temperature  of  5°C.  (23°F.)  for  about  24  hours,  until 
it  is  completely  frozen  ;  it  is  then  taken  into  a  room  and  allowed  to
