The reasons which have caused the adoption of the terms made use of in the following system, are fully given in their proper place, and it only remains for the Author to notice that the terms "Curvilinear" and "Rectilinear" were first proposed by a writer in the "British Critic," some years ago, as a substitute for Mr. Rickman's terms "Decorated" and "Perpendicular;" and in a sense, therefore, as regards the former of these terms, essentially different from that in which it is here proposed to be applied. The rest must be more or less familiar to all who have been of late engaged in the study.

The Author desires to take this opportunity of acknowledging his obligations to Mr. T. Austin, by whom all the subjects, with one exception, have been measured and drawn from the buildings themselves; as well as to Mr. G. B. Smith, by whom the whole have been engraved on steel, for the accuracy and appearance of the principal illustrations.
