(Rep.  de  pharm.,  August,  1893,  P-  34  0  by  the  following  process  by 
which  he  obtains  a  solution  more  concentrated  than  can  be  prepared 
by  using  simply  water  as  a  solvent.  He  dissolves  8  gm.  of  salicylic 
acid  in  24  gm.  of  90  per  cent,  alcohol ;  also  4  gm.  of  sodium  borate 
in  8  gm.  neutral  glycerin,  mixes  the  two  solutions  and  makes  up  to 
100  gm.  by  distilled  water. 
Trisulphide  of  arsenic,  according  to  D.  Vitali  (Boll,  chim.-farm., 
through  Rep.  de  pharm.,  August,  1893,  p.  363),  is  absorbed  by  the 
organism  in  small  doses,  and  is  transformed  into  arsenious  acid, 
which  is  eliminated  by  the  urine.  Sulphide  of  arsenic,  deprived  of 
arsenic  acid,  has  no  direct  influence  on  the  organism,  but  favors  the 
action  of  small  doses  of  this  acid. 
The  elimination  of  various  medicaments  after  rectal  injection,  is 
reported  upon  by  Kandidoff  in  a  preliminary  communication  ( Vratch, 
x^93»  P-  353  ;  nouv.  rem.,  August,  1893,  p.  350),  in  which  he  arrives 
at  the  conclusion,  that  quinine  hydrochlorate,  potassium  iodide, 
potassium  bromide,  sodium  salicylate,  arsenic  and  antipyrine  are  all 
eliminated  by  the  mucous  membrane  of  the  stomach,  and  that  this 
elimination,  in  the  case  of  all,  excepting  the  quinine,  commences 
almost  as  soon  as  the  elimination  by  the  urine,  and  that  tannin  is 
passed  neither  in  the  stomachal  contents  nor  in  the  urine. 
Separation  of  iodine. — The  following  gargle  was  recently  pre- 
scribed (Jour.de  Pharm.  d'Anvers,  June,  1893,  p.  212):  Iodine,  25 
cgm.;  potassium  iodine,  I  gm.;  tannin,  2  gm.;  potassium  bromide, 
10  gm.;  distilled  water,  50  gm.;  glycerin,  50  gm.;  oil  of  peppermint, 
20  drops.  In  dispensing  this,  if  the  four  solid  substances  are  pulver- 
ized and  mixed,  then  dissolved  in  the  glycerine  and  water,  a  pro- 
duct is  obtained  in  which  the  iodine  has  completely  separated. 
This  inconvenience  can  be  avoided  by  mixing  intimately  the  iodine, 
the  iodide  and  the  tannin,  dissolving  the  mixture  in  the  distilled 
water,  which  will  require  at  least  two  hours,  then  adding  succes- 
sively the  bromide,  the  glycerin  and  finally  the  oil  of  peppermint. 
By  this  procedure  a  perfectly  limpid  brown  liquid  is  obtained. 
Infant  powders. — A  writer  in  gior.  di  farm,  et  di  chim.,  1893,  P- 
302  (through  Rep.  de  Pharm.,  August,  1893,  p.  364),  gives  the 
following  formula : 
Starch,  250  gm.;  precipitated  calcium  carbonate,  150  gm.;  dried 
alum  in  very  fine  powder,  15  gm.;  boric  acid,  15  gm.;  carbolic 
acid,  3  gm.    Aromatize  with  oil  of  citron.
