Sec. 17. And if the vessel arrive at any other place, she may be forced to repair to that appointed. Sec. 19. Any Master having touched at infected places, &c. and omitting to disclose the same, or to hoist prescribed signals,[214] shall be guilty of felony without clergy. Sec. 19. Commanders must deliver up bills of health, manifest log book and journal, under penalty of £100. Sec. 20.

Sec. 23. Persons so escaping may be seized by any one for the purpose of being carried before a Justice of the Peace, who by warrant may direct their conveyance to the vessel or lazaret from which they have escaped, or confine them in such place of custody, (not being any public jail,) and under such restrictions as to having any communication with any other persons, as may in the discretion of such Justice of the Peace or Magistrate, (_calling to his aid, if he shall see fit, any Medical person_,) appear to be proper.
