Liquor  Ferro-mangani  peptonati. — 100  citric  acid  are  dissolved  in 
50  cc.  distilled  water  and  neutralized  with  ammonia  water  (about  20  o 
are  necessary).  24  o  liq.  ferri  peptonati  (see  Am.  Jour.  Pharm.,  1888, 
5 14)  are  carefully  boiled  with  1 50-0  distilled  water  until  dissolved,  the 
ammonium  citrate  solution  added  and  also  a  solution  of  3-7  pure 
crystallized  manganous  chloride  in  io-o  distilled  water ;  the  follow- 
ing  mixture  is  next  added  :  500  0  distilled  water,  ioo-o  cognac,  075 
each  of  tinctures  of  Ceylon  cinnamon  and  vanilla,  1-5  aromatic 
tincture  and  2  drops  acetic  ether ;  finally  sufficient  water  to  make 
1  ooo-o.  The  above  directions  must  be  strictly  followed  and  then 
will  furnish  a  preparation  containing  0-6  per  cent,  iron  and  o- 1  per 
cent,  manganese. 
Manganese  saccharate,  M.  mannitate  and  M.  dextrinate. — 75  0  pure 
permanganate  of  potassium  are  dissolved  by  the  aid  of  heat  in 
4500*0  distilled  water  and  allowed  to  cool;  with  stirring  45-0  white 
sugar  or  45-0  alcohol  are  added  and  set  aside  for  24  hours.  The 
precipitate  is  washed,  by  decantation,  with  distilled  water  unt\l  the 
washings  leave  no  residue  upon  evaporation ;  it  is  then  collected 
upon  a  cloth  strainer  and  expressed  until  it  weighs  300-0.  The 
moist  precipitate  is  next  triturated  with  900-0  sugar,  mannite  or 
dextrin,  as  the  case  may  be,  225-0  solution  of  sodium  hydrate  added 
and  warmed  in  a  closed  vessel  in  a  steam-bath  until  a  drop  taken 
out  dissolves  perfectly  in  water ;  it  is  then  evaporated  to  dryness 
and  powdered. 
The  preparations  contain  3  per  cent,  manganese  ;  by  taking  only 
225-0  sugar,  mannite  or  dextrin  instead  of  900-0  preparations  con- 
taining 10  per  cent,  manganese  can  be  made.  These  preparations 
are  easily  soluble  in  water;  concentrated  solutions  are  permanent, 
dilute  solutions  of  the  saccharate  precipitate  after  a  time,  but  of  the 
other  two  are  permanent.  The  solutions  can  be  acidified  with 
citric  acid  without  precipitation. 
"Eucalyptus  rostrata  in  sea-sickness."— Dr.  Russell  {British  Medical. 
Journal, February  22, 1890)  finds  the  eucalyptus  rostrata  "red  gum"  more  effective 
in  checking  sea-sickness  than  any  of  the  other  remedies  hitherto  recommended. 
He  finds  lozenges,  each  containing  one  grain  of  the  eucalyptus  gum,  the  most 
convenient  form  of  administration,  one  being  taken  when  sickness  is  coming  on. 
Action  of  Hydraeethi. — Oestreicher  has  found  this  remedy  {Bert.  klin. 
Woch.)  of  some  slight  service  in  psoriasis,  but  apt  to  give  rise  to.  so  alarming 
symptoms  of  poisoning  that  it  cannot  be  commended. — N.  Y.  Med.  Jour,,
