is still more
curious, the thickness of the yellow bricks used for the walls varies
considerably, from two inches to four; and their length also, some of
the larger pieces used in important positions being a foot and a half
long.

With these two kinds of brick, the builder employed five or six kinds of
marble: pure white, and white veined with purple; a brecciated marble of
white and black; a brecciated marble of white and deep green; another,
deep red, or nearly of the color of Egyptian porphyry; and a grey and
black marble, in fine layers.

Sec. XX. The method of employing these materials will be understood at
once by a reference to the opposite plate (Plate III.), which represents
two portions of the lower band. I could not succeed in expressing the
variation and chequering of color in marble, by real tints in the print;
and have been content, therefore, to give them in line engraving. The
different triangles are, altogether, of ten kinds:

a. Pure white marble with sculptured surface (as the third and fifth
in the upper series of Plate III.).

b. Cast triangle of red brick with a sculptured round-headed piece of
white marble inlaid (as the first and seventh of the upper
series, Plate III.).

c. A plain triangle of greenish black marble, now perhaps
considerably paler in color than when first employed (as the
second and sixth of the upper series of Plate III.).

d. Cast red brick triangle, with a diamond inlaid of the
above-mentioned black marble (as the fourth in the upper series
of Plate III.).

e. Cast white brick, with an inlaid round-headed piece of marble,
variegated with black and yellow, or white and violet (not seen
in the plate).

f. Occurs only once, a green-veined marble, forming the upper part of
the triangle, with a white piece below.

g. Occurs only once. A brecciated marble of intense black and pure
white, the centre of the lower range in Plate III.

h. Sculptured white marble with a triangle of veined purple marble
inserted (as the first, third, fifth, and seventh of the lower
range in Plate III.).

i. Yellow or white marble veined with purple (as the second and sixth
of the lower range in Plate III.).

k. Pure purple marble, not seen in this plate.
