(Excellent  result  with 
malt  extract;  action 
of  saliva  arrested,  in* 
two  hours  paste  only 
liquefied. 
]  Diastatic  power  of  malt 
1    extract  decreased,^. 
V  and   arrested  when 
acid  exceeded  V/^  per 
J  cent. 
} Diastatic  power  of  both 
increased,  that  of  sa- 
liva seven  times- 
greater. 
■]  Action  of  malt  extract 
V  increased,  of  saliva 
j    slightly  retarded. 
]  Favorable  to  malt  ex- 
>  tract;  saliva  nearly 
J  inert. 
]  Lactic  acid,  one-half 
>-  per  ct.,  nearly  stops 
j    all  diastatic  action. 
~|  A   mixture   of  three 
acids,  in  the  propor- 
>  t  ious  indicated  most 
favorable  to  the  ac- 
J    tion  of  saliva. 
I  Absence  of  lactic  acid 
V  diminishes  diastatic 
action  of  both. 
The  alkalies  used  were  calculated  as  anhydrous.  In  testing  the 
liquids,  the  proportion  of  "iodine  used  was  sufficiently  large  to  insure 
an  excess  of  free  iodine.
