separate entrances, or separate staircases, or if such
building shall be hereafter converted, used, or occu-
pied as two or more separate buildings, each having
a separate entrance or staircase, then every such
building shall be deemed to be two or more separate
houses, and such separate houses must be divided
from each other by a party wall, built with the
materials and of the thickness as specified in the
Schedule attached to section 6 of these Regulations.
Where a building is separately divided on its several
floors, no wall shall be considered a party wall which
does not divide the building from the ground line to
the roof.

BRESTSUMMERS.
13. Every brestsummer fixed to carry the front
wall or cornice of a building must be laid upon a
template or corbel of stone, wood, or iron, which
template or corbel must be tailed through such wall
at least two-thirds of the thickness thereof, and
every brestsummer must have at least 4½ inches of
brick or stone work at the end thereof.

COLUMNS, &C.
14. In addition to the supporting walls at the end
of the brestsummer, every brestsummer over 12 feet
span must rest upon one or more sufficient inter-
mediate piers of brick or stone, or on iron columns
standing on solid stone foundations.

BEARINGS OF TIMBERS.
15. The ends of all timbers bearing upon a party
wall exceeding 9 inches in thickness must not be
laid nearer than two inches to the centre thereof,
unless such timbers are separated longitudinally
from the timbers of the adjoining house by at least
4 inches of brickwork, in which case they may bear upon
the wall for two-thirds of its thickness. The ends of
all timbers bearing upon a party wall 9 inches thick
must not project through the wall, but must have 4
inches of brickwork at the ends of same, and all
timbers must be separated from those of the adjoin-
ing house by at least 4 inches of brickwork.

CHIMNEYS.
16. Every chimney and chimney-stack must be
built wholly of brick or stone, with mortar or cement
or concrete, and every such chimney and chimney-
stack must be built from the foundation (and from
the corbels, if corbelled out according to section 18
of these Regulations) to the top thereof, without any
corbelling over whereby any upper part of the brick-
work of such chimney or chimney-stack shall over-
hang any lower part of the brickwork in the front
thereof.

ANGLE CHIMNEYS.
17. The breast of any angle chimney, built in the
internal angle of any building above the ceiling of
any lower storey, shall not exceed 8 feet in width,
and the jambs, breast, and flue must be properly
supported on iron girders, with brick arches, or on
strong stone landings at least 4 inches thick, and
tailed at least 9 inches into each of the two walls
forming such angle.

CHIMNEY JAMBS ON CORBELS.
18. The jambs, breast, and flue of any single or
double chimney may be built upon stone or iron
corbels above the ceiling of any lower storey, but
the projection both of such jambs and breast must
not in any case exceed 14 inches before the face of
the wall or stack to which the same shall join, and
the brickwork must be arched or corbelled over the
whole width of the chimney opening up to the line
of the face of the jambs, in order to provide a solid
bed for the back hearth.

CHIMNEYS.
19. The jambs of every chimney must not be less
than 8½ inches wide on each side of such opening.
The breasts of every chimney, and the front-back
width or partition of every flue, must be at the least
4 inches in thickness of bricks, and the joints of the
work must be filled in with mortar or cement, and
all the inside thereof must be rendered or pargetted.
And no flue may be used for a smoke-flue which is of
less internal diameter in any section than 8½ inches.
20. And as to the back of any single chimney
opening in any building, every such back must be at
the least 8½ inches thick. If two chimneys be built
back to back the thickness between the same must
be at the least of the thickness described for the back
of a single chimney opening.
21. The backs of all chimneys in party walls,
whether built singly or back to back, must be con-
structed of fire-bricks for the whole thickness of the
back, from the surface of the hearth to the height of
12 inches above the underside of the mantelpiece,
unless register grates are fixed in the chimney
openings.
22. No timber must be placed over any opening
for supporting the breast of any chimney, but there
must be an arch of brick or stone over the opening
of every such chimney to support the breast thereof,
and, unless the arch be semicircular, an iron bar or
bars must be built into the jambs at the least 9
inches on each side to tie in the abutments. And no
timber or woodwork must be placed or laid under any
chimney opening, or in any wall under any chimney
opening, within 18 inches at least of the surface of
the hearth to the fireplace of such chimney opening,
and no timber or woodwork must be nearer than one
inch to the opening of any chimney, and no trimmer
must be placed nearer than 18 inches to the front face
of any chimney; neither shall it be lawful to build
in or insert the end of any joists, rafters, beams, or
other timber whatever in any part of any chimney or
flue.

HEARTHS.
23. Front hearths, composed of a slab or slabs,
brick, tile, slates, stone, marble, or other proper and
sufficient substance at the least 9 inches longer than
the opening of every chimney when finished, and at
the least 15 inches in the front of the arch over the
same, must be laid before the opening of every
chimney; and in every floor, except the lowest floor,
such slab or slabs must be laid upon brick trimmer-
arches, or upon a solid bed of cement concrete laid
uniform in thickness, and without a joint, to form a
bed for the hearth, and front hearth or hobs: pro-
vided, nevertheless, that the boarding under the front
hearth to carry the concrete bed be not nearer to the
finished surface of the hearth than 6 inches at the
least. Should the joists not be deep enough to allow
of such depth of 6 inches being obtained, a brick
trimmer-arch must in all cases be used. In the lowest
floor the slab or slabs may be laid on a brick or stone
fender or bedded on the solid ground.
24. The back hearth of every chimney must be
laid and bedded wholly on brick or stone or other
incombustible materials, which must be solid for a
depth of 9 inches at the least below the surface of
the hearth.

OVENS, FURNACES, &C.
25. Every oven, furnace, close fire, or forge must
be 6 inches at least from any party wall, and must
not be upon or within a distance of 18 inches of any
timber or woodwork, measured from the outside of
the brickwork; and the floor on or above which such
oven, furnace, or close fire or forge shall be built or
fixed, must be formed and paved under same, and for
