C.  Like  phenol,  which  it  resembles  very  much,  it  has  no  acid  reac- 
tion, does  not  contain  the  group  COOH  and  also  forms  crystallizable 
compounds  with  alkalies.  When  heated  with  hydriodic  acid  it  evolves 
methyl-iodide,  and  when  fused  with  potassium  hydrate,  it  forms  proto- 
catechuic  acid  C6H3  (OH)2  COOH,  with  baryta  and  tin-dust  it  forms 
about  10  per  cent,  methyl-eugenol.  When  taken  internally  the  greater 
part  of  it  is  eliminated  by  the  urine,  in  which  however  it  cannot  be 
detected  by  its  odor  nor  by  distillation,  but,  if  allowed  to  decompose, 
the  characteristic  odor  is  at  once  perceptible,  and  when  extracted  with 
alcohol  shows  the  characteristic  deep-green  coloration  with  ferric  chlo- 
ride. Eugenol  has  been  given  in  doses  of  3  grams  per  day  dissolved 
in  alcohol  and  diluted  with  water.  As  an  antiseptic,  it  is  superior  to 
phenol ;  as  a  febrifuge,  it  is  not  as  efficacious  as  quinine,  salicylic  acid, 
antipyrine  or  thalline. — Phar.  Zeitschrift  far  Russland,  xxv,  page  723. 
Preservation  of  ferrous  sulphate. — To  preserve  ferrous  sulphate — 
crystalline  or  precipitated — Gawalowski  places  in  the  salt  an  epouvrette 
half-filled  with  an  alkaline  solution  of  pyrogallic  acid.  The  epouvrette 
is  placed  in  such  a  way  that  the  opening  is  sufficiently  above  the  salt. 
With  a  good  stopper,  ferrous  sulphate  can  be  kept  from  two  to  three 
years. — Ibid.,  xxv,  page  759. 
Iodoform  pencils : — I.  Iodoform  powdered  50,  starch  (or  gum 
arabic)  5,  distilled  water  9'5  ;  make  pencil  8  centimeters  long  and  4 
millimeters  thick.  II.  Iodoform  powdered  5,  starch  or  gum  arabic  6, 
glycerin  9'5  ;  make  a  pencil  6  centimeters  long  and  1  centimeter  in  thick- 
ness.— Ibid.,  xxv,  page  760.  See  also  Am.  Jour.  Phar.,  1885,  page  30. 
Naphthalin  as  a  vermifuge. — Koriander  gives  children  from  1  to  3 
years  old  0.15  to  2.0  grams  twice  daily  ;  to  adults  he  gives  from  1.25 
to  6.0  grams  per  day  in  powders  with  sugar.  Koriander  has  fre- 
quently noticed  excellent  results  from  naphthalin  when  given  for  tape- 
worm.— Phar.  Zeitseh.  fur  Russl.,  xxv,  page,  786. 
Impervious  Shoe  Blacking. — Wax  10,  spermaceti  6,  oil  of  turpentine 
66,  asphalt  varnish  5,  pulverized  borax  1,  nitrobenzol  1,  grape-vine 
charcoal  5,  Berlin  blue  2.  Melt  the  wax,  add  the  borax  and  stir  un- 
til a  jelly  is  formed.  In  another  vessel  melt  the  spermaceti,  add  the 
asphalt  varnish  previously  mixed  with  the  turpentine,  stir  well  and 
add  to  the  wax,  lastly  add  the  coloring  previously  mixed  with  a  small 
quantity  of  the  mass,  perfume  with  nitrobenzol  and  fill  in  boxes.  Ap- 
ply a  small  quantity  with  a  rag  and  brush.  To  be  used  only  once  a 
week. — Ibid.,  xxv,  page,  792.
