Section 690 of the Penal Code lays down the statute very clearly on this

subject: “Where a person is hereafter convicted of a felony, who has

been before that conviction, convicted in this State, of any other

crime, or where a person is hereafter convicted of a misdemeanor, who

has been already five times convicted in this State of a misdemeanor, he

may be adjudged by the Court, in addition to any other punishment that

may be inflicted upon him, to be an habitual criminal.”
