Examples of an impossible crime, which formerly was not punishable but is now under article 59 of the Revised Penal Code, are the following: 

 (1) When one tries to kill another by putting in his soup a substance which he believes to be arsenic when in fact it is common salt; and 

(2) when one tries to murder a corpse. (Guevara, Commentaries on the Revised Penal Code, 4th ed., page 15; decision, Supreme Court of Spain, November 26, 1879; 12 Jur. Crim., 343.
