[2] I beg again to refer to the admirable article on this phase of architecture, which Mr. Freeman terms _Primitive Romanesque_, in the fifth volume of his _Norman Conquest_. (G. G. S. 1878.) [3] For illustration see “Digression concerning Windows,” inserted between Lectures VII. and VIII. Fig. 157. [4] I must apologise for this term. I know the best judges pronounce it wrong; but I really am ignorant as to what other will express the same meaning. (G. G. S. 1878.) [5] See Worth Church, p. 44, Figs. 216, 217.
