The manner of numbering buildings shall be as follows: one whole number shall be allowed to each twenty-five feet of ground whether improved or vacant and any division of such place shall be designated by an additional fraction as the case may require. All streets running north and south from Hanover Street shall be numbered with odd numbers on the west side of street and even numbers on the east side thereof. All streets running east and west shall be numbered from their eastern termini westward with odd numbers on the north side of such streets and even numbers on the south side.
