INFLtJENCE  OP  DRYlKa,  ETC. 
separated  more  of  Wiggers'  ergotin  and  crystals  of  mycose ; 
the  clear  liquid  was  evaporated  as  before  to  near  dryness,  (the 
residue  of  the  fresh  was  more  granular)  and,  since  pure  ether 
was  without  effect,  treated  with  alcoholic  ether,  which  on  evapo- 
ration yielded  yellow  acicular  crystals,  regarded  as  pure  Bon- 
jean's  ergotin,  (0*25  per  cent,  from  the  fresh,  0*20  from  the  old). 
The  extract  treated  with  alcoholic  ether  was  entirely  soluble  in 
absolute  alcohol  except  a  little  mycose  ;  on  spontaneous  evapo- 
ration a  little  more  mycose  was  separated^  and  then  a  reddish 
(rather  darker  from  old  ergot)  oily  mass  was  left,  consisting 
mainly  of  lactic  acid. 
Rhus  radicans,  (leaves,  July).  The  distillate  from  the  dried 
leaves  was  without  odor  and  acid  reaction,  and  did  not  reduce 
the  salts  of  silver,  platinum  and  gold. 
Ruta  graveolens,  (leaves,  July).  The  tincture  of  the  fresh 
leaves  deprived  of  the  alcohol  by  distillation  separated  an  odorous 
green  oil,  which,  removed  by  ether,  left  a  yellowish  granular  glu- 
coside  of  a  bitter,  somewhat  acrid  taste.  From  the  dried  leaves 
the  oil  was  not  obtained,  and  the  glucoside  merely  as  a  brown  ex- 
tract. 
Valeriana  officinalis,  (root  collected  in  September,  from  high 
dry  situations).  The  resin  of  the  dried  root  is  more  acrid  than 
in  the  fresh.  250  grm.  of  the  former  yielded  1  grm.  valerianic 
acid.  The  distillate  from  the  fresh  root  was  neutral,  had  a  slight 
odor,  but  on  exposure  to  the  air  in  the  presence  of  alkalies, 
yielded  1-6  valerianic  acid. 
Prunus  lauro-cerasus,  (leaves,  June).  Lose  all  their  virtues 
by  drying. 
Bryonia  dioica,  (root,  October).  Results  alike  from  the  fresh 
and  dried. 
Inula  Heleniiam,  (root  of  second  years  growth,  October).  The 
constituents  are  somewhat  altered.  The  sugar  is  obtained  from 
the  fresh  root  in  white  hexagonal  prisms,  from  the  dried  root 
granular. 
Saponaria  officinalis,  (root,  October).  The  saponin  from  the 
fresh  root  is  white  granular,  from  the  dried  amorphous  colored. 
Juniperus  Sabina,  (leaves  and  tops,  July).  The  dried  yields 
a  browner,  less  odorous,  more  acrid  tincture.
