Preservation  of  Hydrocyanic  Acid. — Mr.  John  Williams  has  continued 
his  experiments  on  the  preservative  influence  of  glycerin  upon  hydro- 
cyanic acid  (see  "Am.  Jour.  Phar.,"  1874,  p.  487).  Two  samples,  of 
ten  fluidounces  each,  and  containing  respectively  4*5  and  2  per  cent, 
of  acid,  were  put  in  pint  bottles,  glass  stoppered,  but  not  tied  over  or 
inverted  ;  each  contained  20  per  cent,  of  Price's  pure  glycerin.  The 
bottles  were  opened  after  six  and  twelve  months,  and  the  acids  were 
found  not  to  have  diminished  in  strength  or  altered  in  appearance. 
German  glycerin  was  found  to  assume  a  yellow  color  with  hydrocyanic 
acid. — Ihid.,  Sept.  25. 
Syrup  of  Tolu. — Regarding  the  resin  of  tolu  as  the  main  or  sole  act- 
ive principle,  Henrotte  is  in  favor  of  retaining  it  in  the  syrup,  and 
effects  its  permanent  emulsion  in  the  following  manner:  10  grams  of 
finely-powdered  tragacanth  are  triturated  with  sufficient  simple  syrup 
to  form  a  mucilage  ;  40  grams  of  tincture  of  tolu  are  added  and  an 
emulsion  made,  to  which  enough  simple  syrup  is  added  to  make  the 
whole  weight  1,000  grams. — four,  de  Phar.  d'Anvers,  1875,  p.  337—

Administration  af  Raw  Meat. — Dr.  Lailler  proposes  to  mix  100  grs. 
of  grated  raw  meat  with  40  grs.  of  powdered  sugar,  adding  afterwards 
20  grs.  of  Bagnols  wine  (sparkling  ?)  and  3  grams  of  tincture  of  cin- 
namon. This  mixture  has  an  agreeable  taste  and  is  easily  digested. —

Solubility  of  Borax  in  Glycerin  — According  to  Gandolphe,  glycerin 
dissolves,  at  the  ordinary  temperature,  its  own  weight  of  borax  by  tri- 
turating them  in  a  mortar,  or  more  rapidly  by  applying  the  heat  of  a 
water-bath.  This  solution  which  keeps  unaltered  is  well  adapted  for 
mouth  washes  after  the  addition  of  some  clarified  honey  or  honey  of 
roses.  100  parts  of  water  dissolve  only  8*33  parts  of  borax.  Boracic 
acid  is  likewise  more  soluble  in  glycerin  than  in  water,  but  not  to  the 
same  degree  as  borax. — Ibid.,  from  Union  Phar.
