I      March,  1869. 
and  adding  to  the  reserved  portion,  a  floccalent  matter  was  separated 
rising  to  the  surface  and  leaving  the  liquid  clear. 
On  percolating  the  drug  with  the  same  mixture  of  alcohol  and  water, 
omitting  the  glycerin,  the  percolates  were  nearly  clear  until  the  evap- 
orated portion  was  added  to  the  reserved  liquid,  when  it  became  turbid. 
A  mixture  of  two  parts  of  alcohol  and  one  of  water  yielded  a  percolate 
from  which  a  precipitate  separated,  which  was  increased  on  the  addi- 
tion of  the  evaporated  portion.  The  percolate  of  the  drug  obtained 
with  diluted  alcohol  was  cloudy  and  deposited  a  precipitate. 
Syrupus  Rhei  aromaticus. — John  H.  Bear,  Ph.  G.,  proposes  the 
addition  of  a  little  borax  whereby  a  clear  and  apparently  unobjection- 
able preparation  is  obtained.  For  one  ounce  avoirdupois  of  the  aro- 
matic tincture  of  rhubarb  18  grains  of  borax  are  used. 
Bases  for  Vnguentum  Iodi. — Charles  W.  Cannon,  Ph.  G.,  has  ex- 
perimented with  lard,  lanolin  and  petrolatum  as  the  base  for  iodine 
ointment ;  and  after  keeping  the  ointments  under  various  conditions 
in  the  dark,  or  exposed  to  diffused  daylight  or  to  sunlight  determined 
the  amount  of  iodine  by  dissolving  it  in  alcohol  and  estimating  it 
with  volumetric  solution  of  sodium  hyposulphite.  Lanolin  and  lard 
yielded  the  iodine  to  the  solvent  quite  readily,  while  petrolatum  per- 
sistently retained  a  portion  of  it.  The  largest  amount  of  iodine  was 
invariably  recovered  from  the  lanolin,  and  this  is  recommended  as  the 
best  base  for  iodine  ointment ;  the  well  known  qualities  of  lanolin 
furnish  additional  reasons  for  its  use  in  this  connection. 
Unguentum  Aquo3  Rosaz. — William  Stengelin,  Ph.  G.,  furnishes  the 
following  formula,  which  is  stated  to  yield  an  excellent  preparation : 
Expressed  oil  of  almond   i  4  ounces. 
White  wax  1  ounce. 
Spermaceti  ?          6  drachms. 
Distilled  water  ounces. 
Oil  of  bergamot  5  drops. 
Otto  of  rose  5  drops. 
In  order  to  obtain  it  of  a  light,  frothy  consistence  it  is  recommended 
to  beat  it  with  a  wooden  stirrer  having  a  perforated  blade,  which 
should  be  dexterously  worked,  and  is  afterward  readily  cleaned. 
Fluid  extract  of  viburnum,  in  doses  of  3  i,  has  been  given  in  Bellevue  and 
other  hospitals  against  vomiting  of  pregnancy,  with  uniformly  successful  re- 
sults.
