1. That no person may be convicted more than once on account of violations occurring by reason of failure, on a series of days, to furnish such statements; and
2. That nothing contained herein shall be deemed a bar to subsequent prosecutions for violations of the provisions of this chapter occurring subsequent to a prior conviction or acquittal of a violation thereof.
