Pencils  of  Iodoform  are  prepared  by  K.  Mueller  by  triturating^ 
92*5  grains  finely-powdered  iodoform  with  a  solution  of  5  grams 
gum  arable  in  2*5  gni.  each  of  glycerin  and  water  until  a  plastic 
mass  is  obtained,  which  is  rolled  out  to  the  desired  thickness,  and  cut 
into  pieces  of  about  10  centimetei's  (4  inches).  Should  the  mass 
become  too  brittle  a  few  drops  of  water  are  added.  The  pencils 
become  dry  in  about  two  hours,  and  to  {)revent  flattening  are  laid  upon 
wax-paper,  creased  so  as  to  form  a  gutter. — Phar.  Zfg.,  1882.  No. 
13,  p.  92. 
Cheap  Logwood  Ink: — J.  Schmieden  recommends  the  following  pro- 
cess :  Dissolve  extract  of  logwood  750  gm.,  in  14  liters  of  boiling 
water,  add  750  gm.  of  alum,  and  when  dissolved  200  gm.  of  sulphuric 
acid,  and  with  continuous  agitation  80  gm.  of  yellow  potassium  chro- 
mate,  previously  dissolved  in  500  gm.  of  lukewarm  water  ;  finally, 
add  a  solution  of  100  gm.  of  ferrous  sulphate  in  300  gm.  of  crude 
hydrochloric  acid,  dissolve  in  the  ink  100  gm.  of  gum  arabic  and 
dilute  with  water  to  20  liters.  The  ink  writes  with  a  reddish  color,, 
but  on  drying  is  deep  black. — Phar.  Ztg.,  1882,  No.  11,  p.  78. 
Aqua  traumatica  Sendneri. — Cinchonine  sulphate  1*0,  alum  2*0 
are  powdered  and  dissolved  in  distilled  water  200*0;  to  this  is  added 
tincture  of  opium  5*0  and  tincture  of  benzoin  20*0.  The  milk-like 
mixture  is  either  injected  into  suppurating  wounds  or  it  is  applied 
upon  linen  or  lint ;  it  is  a  disinfectant,  soothes  pain,  and  promotes 
healing.  Quinidine  sulphate  may  be  substituted  for  the  cheaper 
cinchonine  salt. — Phar.  Centralhalle,  1882,  p.  133. 
Lithium  iodide  is  recommended  by  Prof.  Zeisst,  of  Vienna,  in  such 
cases  where  other  alkaline  iodides  and  iodine  preparations  are  not 
tolerated.    It  is  conveniently  given  in  pills  as  follows ;

8.  .  One  pill  morning  and  night. 
For  obtaining  the  salt,  a  solution  of  ferrous  iodide  is  first  prepared' 
from  127  parts  iodine,  33  parts  iron  filings,  and  300  parts  water.  To 
this  is  gradually  added  38  parts  lithium  carbonate,  and  after  decom- 
position, the  liquid  is  filtered  and  evajiorated  in  the  usual  manner. —
