The  solution  must  be  used  cautiously,  so  as  not  to  come  into  con- 
tact with  the  eyes,  lips  and  other  tender  portions  of  the  body.  For 
killing  vermin  on  animals  it  is  applied  with  a  brush,  previously  diluted 
with  100  or  120  parts  of  water,  and  with  linen  or  cotton,  also  for  dis- 
infecting offensive  sores.  When  used  for  protecting  horses,  etc.^ 
against  flies  and  other  insects,  very  little  of  the  composition  is  applied 
with  a  brush  once  or  twice  a  d?iy.—Phar.  Centraib. ^  Ja.n.  15,  1880,  p.  27. 
Fennel-honey  consists  of  purified  honey,  500  grams;  malt-sugar, 
1,000  grams;  fennel  oil,  5  drops,  and  a  little  glycerin. — Pharm.  Ztg.^

Clarified  Honey. — Frank  Juehling  objects  to  the  use  of  tannin,, 
because  honey  thus  purified  always  contains  traces  of  tannic  acid,  which 
will  react  with  iron,  quinia  and  other  salts.  He  prefers  the  following 
method:  Six  kilograms  of  honey  are  dissolved  in  3  kilograms  of  water 
on  a  water-bath.  About  one  sheet  of  filtering-paper,  previously  tri- 
turated into  a  pulp  with  water,  and  freshly-precipitated  and  washed 
aluminium  hydrate  are  added,  until  a  filtered  sample,  transferred  to  a 
test  tube,  appears  perfectly  bright.  After  cooling,  the  liquid  is  passed 
through  a  linen  or  cotton  strainer  and  evaporated  to  the  weight  of  6 
kilograms.  The  quantity  of  aluminium  hydrate  precipitated  from  500 
grams  of  alum  and  600  grams  of  soda  is  more  than  sufficient. — Ibid.y

Extemporaneous  Preparation  ot  Syrup  of  Licorice.  —  Juehling 
prepares  a  syrup,  equal  in  strength  to  that  of  the  German  Pharm- 
acopoeia, by  mixing: 
5c     Essentias  Hquiritiae,  ....  lo'o 
Syrupi  simplicis,    .  ...  180  0 
Mellis  depurati,  ....      120-0  M. 
Essentia  liquiritia  is  made  by  extracting  twice  i, 000  grams  of  licorice 
root  with  3,000  grams  of  water,  evaporatiog  the  infusion  to  500  grams,, 
adding  500  grams  of  alcohol,  filtering  and  evaporating  to  333  grams 
(consistence  of  honey). — Ibid. 
The  solubility  of  Ozone  in  water  has  hitherto  been  a  disputed 
question.  A.  R.  Leeds  conducted  ozone  into  two  bell-glasses  con- 
taining water,  which  covered  lead  sulphide  in  one  and  silver  in  the 
other  glass.  Sufficient  ozone  was  absorbed  by  the  water  to  cause  oxi- 
dation of  the  silver  and  of  the  lead  sulphide,  in  the  latter  case  appar- 
ently with  the  production  of  brown  anhydrous  lead  peroxide  and  of  free 
sulphuric  acid. — Ber,  d.  Deutsch.  Chem,  Ges.^  1^79?  P-  i^S^*
