Scott's list of striking London examples[7] of Gothic architecture
(with the omission of such examples as are more antiquarian than
architectural in their interest):--

_Transitional._--The round part of the Temple Church.

and Lady Chapel of St. Mary Overy, Southwark; Chapel of
Lambeth Palace.

_Advanced Early English_ (passing to decorated).--Eastern
part of Westminster Abbey generally and its Chapter House.

_Early Decorated._--Choir of Westminster, (but this has been
much influenced by the design of the earlier parts
adjacent); Chapel of St. Etheldreda, Ely Place, Holborn.

_Late Decorated._--The three bays of the Cloister at
Westminster opposite the entrance to Chapter House; Crypt of
St. Stephen's Chapel, Westminster; Dutch Church, Austin

GOTHIC ARCHITECTURE.--ENGLAND.

ANALYSIS OF BUILDINGS.--FLOOR, WALLS, TOWERS, GABLES, COLUMNS.

_Floor, or Plan._

The excellences or defects of a building are more due to the shape and
size of its floor and, incidentally, of the walls and columns or piers
which inclose and subdivide its floor than to anything else whatever.
A map of the floor and walls (usually showing also the position of the
doors and windows), is known as a plan, but by a pardonable figure of
speech the plan of a building is often understood to mean the shape
and size and arrangement of its floor and walls themselves, instead of
simply the drawing representing them. It is in this sense that the
word plan will be used in
