In adopting this extension of the term Gothic so as to apply it to the whole style, it may be requisite to distinguish between round arched and pointed — arched Gothic, or, as it may be more succinctly ex pressed, between the Round and Pointed styles. Whatever term we use, this is indispensable; for Durham and York, Spires and Cologne are buildings of the same class, and must be regarded as belonging to one style: the mere introduction of the pointed arch is too trivial a difference to make such a separation as has hitherto been assumed to exist.
