frame firmly in its place. For rectangular buildings, with
out towers at the corners, angle bricks are specially made.
The inventor Claims that the circular brick are especially
valuable for towers, tall chimnneys, light-houses, reservoirs
for grain and for water couduits, cisterns, tubs for distill-
ers, dyers, etc. Some of these Claims seem fanciful and
not duly sustained by experience, beiug apparently sugges-
tions. For example, a tall cistern is represented, built to
hold five metres in depth of water, and warranted to resist
the pressure. The walls are double and connected at intcr-
vals Avith tie-bricks, leaving an air-space between. The
bottom is to be of sheet iron "three to five millimetres” in
thickness, Avith the edges turned up so as to hold the lower
course of bricks and to prevent the iron from draAving in by
sagging.
It is proposed to malte roofs and arches of these brick,
each brick with six dovetail joints, and 0 m, 320 by ()'“• 190
by 0 m .060. These, it is stated, can be laid for seven
francs the square metre, including the cement and fifteen
bricks at tAventy Centimes each. The average prico is
about seventy-five francs the thousand for bricks, twenty-
five centimetres by twelve centimetres by six centimetres.
The mean price per square metre of Avall built of a single
thickness of brick 0 m .14 thick, is stated to be nine francs
seventy-five Centimes; and of a square metre of double aauII
with bricks 0 m .075 broad, fourteen francs.
There was no opportunity of verifying any of these State
ments, and no references wcre made to any constructions
made in tliis manner.
