the  solvent  the  residue  separated  white,  partly  crystalline,  partly 
amorphous  crusts,  which,  after  washing  with  cold  alcohol  were  dis- 
solved in  boiling  alcohol,  when  upon  the  cooling  of  the  solution  the 
glucoside  separated.  It  is  only  slightly  soluble  in  cold  water  and 
alcohol,  but  is  soluble  in  hot  water  and  hot  alcohol;  it  has  the 
formula  C22H28O10  -f-  2H20  becomes  anhydrous  at  no°C.  and  at 
higher  temperature  is  colored  red-violet,  and  melts,  forming  a 
transparent,  glassy  mass  ;  dilute  acids  yield  dextrose,  and  a  red- 
brown  resinous  substance,  soluble  in  ether  and  alcohol,  this  decom- 
position is  attended  by  a  strong  odor,  recalling  balsam  of  Peru.  A 
preliminary  examination  of  the  bark  gave  indications  of  alkaloids 
with  Mayer's  reagent  and  potassium  tri-iodide ;  the  aqueous  decoc- 
tion with  lead  subacetate  gave  a  copious  precipitate  which  after 
washing  with  water  and  alcohol  was  decomposed  by  hydrogen  sul- 
phide ;  after  filtering  and  evaporating  a  yellowish  powder  was 
obtained,  soluble  in  hot  water,  but  precipitating  again  upon  cooling, 
this  aqueous  solution  -gave  the  alkaloidal  indications ;  it  is  soluble 
in  alkalies  and  alkaline  carbonates.  Saponin  was  tested  for,  but 
without  confirmatory  results. — W.  von  Schulz,  Pharm.  Ztsch.  f*

Resorbin,  a  new  ointment  base,  is  an  emulsion  of  sweet  almond 
oil,  containing  a  small  quantity  of  wax,  with  a  dilute  aqueous  solu- 
tion of  gelatin  or  soap. — Pharm.  Centralhalle ,  1893,  688. 
Sanguinal,  a  blood-forming  medicament,  contains  10  per  cent,  of 
pure  oxyhemoglobin,  46  per  cent,  of  the  salts  existing  in  the  blood, 
and  44  per  cent,  of  freshly-peptonized  muscular  albuminoids. — 
Pharm.  Centralhalle,  1893,687. 
Phosphorus  is  prepared  by  a  process  patented  by  Rossell,  of  Bern, 
by  which  glacial  phosphoric  acid  or  alkaline  metaphosphates  are 
heated  with  metallic  zinc  or  aluminum,  the  metals  dissolve  in  fused 
acid  or  its  salts,  and  phosphorus  distils  over ;  this  reaction  takes 
place  at  a  low  red  heat,  whereas  in  the  older  process  of  reducing  the 
metaphosphate  with  carbon  a  very  intense  heat  was  necessary. —

Somatose  is  a  meat  preparation  containing  large  quantities  of 
albumoses  with  very  little  peptone ;  it  is  claimed  to  be  more  easily 
assimilated,  and  more  agreeable,  than  the  usual  meat  preparations 
containing  considerable  peptones. — Dr.  F.  Goldmann,  Sudd.  Apothe- 
ker Ztg.,  1893,  529.
