clear  solution  with  water,  and  has  a  pleasant  sweetish-sour  taste. —

Boracic  and  Boro-carbolic  Lint  and  Cotton  as  Antiseptics. — 
Ed.  Solger  makes  boracic  lint  and  cotton,  of  different  strength,  by 
saturating  the  fabric  with  a  solution  of  10,  15  or  20  parts  of  boracic 
acid  in  90,  85  or  80  of  hot  water.  This  mixture,  which  usually 
deposits  crystals  on  cooling,  is  heated  to  50°C.  so  as  to  re-dissolve  the 
crystals  before  using,  and  the  saturated  lint  or  cotton  is  applied  as  a 
bandage  before  cooling. 
Boro-carbolic  lint  and  cotton  is  made  in  a  similar  manner,  using  a 
solution  of  5  or  10  parts  of  boracic  acid  and  2  parts  of  pure  carbolic 
acid  in  100  parts  of  hot  water  and  5  parts  of  alcohol. — Ibid.,  p.  482. 
Preparation  of  Vanillin  from  Siam  Benzoin. — Chr.  Rump  gives 
the  following  directions  for  preparing  vanillin  :  Two  parts  of  powdered 
Siam  benzoin  and  1  part  of  slaked  lime  are  boiled  with  water  in  an 
iron  kettle,  stirring  constantly  \  the  resulting  solution  of  benzoate  of 
calcium  is  filtered,  the  filtrate  acidulated  with  hydrochloric  or  sulphuric 
acid,  the  precipitated  benzoic  acid  separated  by  filtration,  the  acid 
filtrate  shaken  with  ether  and  the  ether  evaporated  spontaneously.  The 
impure  vanillin  thus  obtained  is  purified  by  re-crystallization  from 
water,  from  which  it  separates  in  long,  thick  white  needles,  turning 
yellow  on  exposure  to  the  air.  It  is  very  soluble  in  ether,  alcohol, 
chloroform,  glacial  acetic  acid  and  slightly  in  cold  benzol,  crystallizing 
from  all  these  solvents  in  well-developed  prismatic  crystals. — Ber.  d,

Benzoic  Acid  Containing  Cinnamic  Acid. — G.  Reichardt  examined 
three  different  lots  of  commercial  benzoic  acid,  and  found  each  to  con- 
tain a  considerable  proportion  of  cinnamic  acid. — Pharm.  Ztg.,  Nov.

Presence  of  Furfurol  in  Commercial  Glacial  Acetic  Acid. — 
Victor  Meyer  stated  some  time  ago  that  apparently  excellent  com- 
mercial so-called  99  to  100  per  cent,  glacial  acetic  acid,  when  brought 
into  contact  with  anilin,  caused  a  beautiful  red  coloration  which  did  not 
appear  any  more  after  the  acid  had  been  distilled  over  chromic  acid ;  he 
now  reports  that  comparative  colorimetric  experiments  have  fully  con- 
vinced him  that  the  color  reaction  is  due  to  the  presence  of  about  0*108  g.
