FOOTNOTES:
[107] I had a real ploughshare on my lecture table; but it would interrupt the drift of the statements in the text too long if I attempted here to illustrate by figures the relation of the coulter to the share, and of the hard to the soft pieces of metal in the share itself.
[108] A sphere of rock crystal, cut in Japan, enough imaginable by the reader, without a figure.
[109] One of William Hunt's peaches; not, I am afraid, imaginable altogether, but still less representable by figure.
[110] The crystal ball above mentioned.
[111] All grandest effects in mouldings may be, and for the most part have been, obtained by rolls and cavettos of circular (segmental) section. More refined sections, as that of the fluting of a Doric shaft, are only of use near the eye and in beautiful stone; and the pursuit of them was one of the many errors of later Gothic. The statement in the text that the mouldings, even of best time, "have no real relation to construction," is scarcely strong enough: they in fact contend with, and deny the construction, their principal purpose seeming to be the concealment of the joints of the voussoirs.
[112] Some of the most precious work done for me by my assistant Mr. Burgess, during the course of these lectures, consisted in making enlarged drawings from portions of photographs. Plate III. is engraved from a drawing of his, enlarged from the original photograph of which Plate I. is a reduction.
