Night

As to what, by the common law, is reckoned night and what day, it seems to be the general oplnlon that, if there be daylight, or crepusculum, enough begun or left to discern a man’s face, that is con-sidered day; and night is when it is so dark that the countenance of a man cannot be dis-cerned. 1 Hale, P. C. 350. However, the limlj: of 9 p. it. to 6 a. u. has been fixed by statute, in England, as the period of night, in prosecutions for burglary and larceny. St 24 & 25 Vlct. c. 96, $ 1; Brown. In Amer-ican law, the common-law definition is still adhered to in some states, but in others “night” has been defined by statute as tbe period between sunset and sunrise
