oxyethyl  groups  with  a  nucleus  also  having  antipyretic  effect,  so  as 
to  produce  a  new  body  of  corresponding  physiological  power.  The 
formula  is  C9H5  (OC2H5)  (NHC2H30)  N.  The  preparation  is  given 
in  doses  of  one  gram  to  alleviate  rheumatic  pain. — Apotheker  Ztg.>

Kamala. — Professor  Fluckiger  recently  received  from  Dr.  M. 
Greshoff,  of  Java,  ripened  capsules  of  the  kamala-plant  which  air-dried 
weighed  207-10  grams;  from  these  were  obtained  1274  gm.  seeds, 
22-66  gm.  kamala  (containing  3-92  per  cent,  moisture)  and  171-70 
gm.  capsule  integuments ;  the  kamala  therefore  amounted  to  1079 
per  cent,  and  was  found  to  yield  from  1-3  to  1-5  per  cent,  ash, 
depending  upon  the  quantity  taken  for  the  determination.  The 
integuments  incinerated  yielded  4-19  per  cent,  ash,  so  that  these,  if 
admixed,  would  not  account  for  the  high  percentage  of  ash  in  the 
commercial  article ;  the  undesirable  parts  of  the  capsule  can  be  so 
readily  separated  by  sifting  that  it  is  not  possible  to  see  how  the 
"  method  of  collecting  "  can  increase  the  percentage  of  ash  unless 
the  collector  use  bolus  or  other  adulterating  agent. 
Attention  is  called  to  the  similarity  in  usage  of  waras  by  the 
Arabs  and  Africans,  and  to  the  open  adulteration  of  the  same  for 
hundreds  of  years  past,  so  that  it  is  not  considered  to  be  an  adulter- 
ation but  a  sacred  custom. — Arch,  der  Pharm.,  1892,  2. 
Bitter  principles — Menyanthin  from  Mcnyanthes  trifoliata  was 
extracted  by  treating  the  powdered  herb  with  ether,  then  with  98  per 
cent,  alcohol;  the  solutions  were  evaporated  to  extract  consistency, 
exhausted  with  water  at  50-600  and  these  aqueous  solutions  sepa- 
rately treated  because  of  the  presence  of  tannin  only  in  the  one  from 
the  alcoholic  extract.  This  was  first  precipitated  with  lead  acetate, 
filtered,  the  excess  of  lead  separated  with  H2S,  warmed  to  remove 
the  excess  of  H2S  and  the  free  acetic  acid  neutralized  by  digestion 
with  barium  carbonate,  and  filtered.  The  aqueous  solution  from 
the  ether  extract  was  agitated  with  moist  aluminium  hydrate  and 
filtered ;  both  filtrates  were  now  treated  in  the  same  manner,  con- 
centrated in  vacuo,  mixed  with  sand,  evaporated  to  dryness, 
extracted  with  alcohol,  this  solution  concentrated  and  impurities 
precipitated  by  addition  of  ether,  and  the  solution  of  the  bitter  prin- 
ciple further  purified  by  treatment  with  animal  charcoal.  Both 
extracts  contained  the  same  principle  which  was  of  a  yellow  color, 
neutral  reaction  and  pure  bitter  taste;  it  was  easily  soluble  in  alcohol
