While it is true, generally speaking, that intoxication is no excuse for the commission of an offense, yet, where a particular, specific, or deliberate intent, such as malice aforethought, in murder, is an essential element of the crime, the accused may show in defense that he was intoxicated to such a degree as to render him incapable of entertaining that intent,15 and the cause of the incapacity is not material, whether drunkenness or other cause.16 It is also competent to show the drunkenness of the accused as part of the res gestae.17
