be liberated on this account in the paunch ; but when it later entered the 

 true stomach, where the solution would become slightly acid, the hydro- 

 cyanic acid would be set free. The result under experiment 13c seems 

 to show that this is true. Digestion first with N/ioo sodium hydroxid, 

 as shown in experiment 13b, prevents the liberation of the hydrocyanic 

 acid. Certainly, then, digestion with A^/50 sodium hydroxid would 

 prevent the liberation of this acid, and yet it is seen by acidifying this 

 solution and allowing further digestion that more than one-half of the 

 hydrocyanic acid was given off.
