The  other  half  of  the  mixture  of  acids  was  dissolved  in  alcohol  and 
treated  with  hydrochloric  acid  gas  ;  by  fractional  distillation  the  ethers* 
thus  formed  were  separated  ;  the  portion  distilling  at  21 50  gave  num- 
bers agreeing  with  the  formula  C9H10O2,  ethyl  ben'zoate ;  that  passing 
over  at  265 0  agreed  with  CnH1202,  ethyl  cinnamate. 
Hence  tolubalsam  contains  free  benzoic  and  cinnamic  acids,  as  well 
as  their  benzylic  ethers. — C.  R.  A.  W.  in  four.  Chem.  Soc. 
Analysis  of  Pumpkin  Seeds. — Nicolai  Kopylow  has  ascertained 
that  these  seeds  contain  no  alkaloid,  nor  could  the  presence  of  a 
glucoside  be  established  which,  by  Dorner  and  Wolkowitsh,  was  sup- 
posed to  exist  therein  and  named  by  them  cucurbitin  (1870).  The 
last  named  authors  had  found  44*50  fixed  oil,  32*75  starch  and  traces 
of  volatile  oil,  resin,  sugar  and  coloring  matter.  Kopylow  ascertained 
the  fat  to  consist  of  the  glycerides  of  palmitic,  myristic  and  oleic  acids, 
and  the  fat  extracted  by  ether  also  to  contain  free  fatty  acids. — Phar,

Euryangium  Sumbul,  according  to  Carl  Wittmann,  occurs  very 
frequently  in  the  neighborhood  of  Chabarowka,  on  the  Amoor  river  in 
Eastern  Siberia,  and  attains  a  height  of  1*5  metres.  The  fleshv 
branching  root  has  at  its  base  a  diameter  of  0*09  metre,  and  possesses 
a  strong  musk  odor  which  is  increased  when  the  root  is  moistened  with 
water.  The  stem  is  fleshy  ;  leaves  are  twice  or  thrice  pinnate,  pinnae 
lanceolate  and  sharply  serrate  ;  umbels  composed  of  30  to  50  rays  ; 
flowers  white  and  small.  It  is  called  by  the  natives  ofuokgi  or  ouchi ; 
by  the  Chinese  'zsouma-tschen-tuk,  and  by  the  Russian  inhabitants  bear's 
claw,  and  is  medicinally  employed  in  various  diseases. 
Another  umbelliferous  plant  occurs  there  having  considerable  resem- 
blance to  the  former,  but  being  somewhat  smaller,  the  leaves  lighter 
colored  and  the  root  destitute  of  musk  odor. — Ibid.,  No.  18.
