Power to Juvenile Court to commit inmate of reform school to prison

19. Where it is made to appear to a Court by the person in charge of a reform school that an inmate of such school, not being a child, has proved to be of so unruly or depraved a character as to make him unfit to be an inmate of the same, the Court may commit such inmate to prison for a period which, together with the period during which he has already been detained in the reform school, shall not exceed the maximum period for which he was liable to be detained in a reform school under the provisions of section 13 of this Law.
