As a specimen of the architectural style of the building, the centre bay-window of the principal front is given, with its section and plan. It is 9 ft. 6 in. across, and 21 ft. 4 in. high, and stands directly over the chief entrance. The construction of a projecting bay-window coming over an archway requires a short description.
The three diagrams on page 495 show the manner in which such windows are corbelled out. The upper

one is a plan of the bottom stone course, immediately over the key-stone of the arch; it shows also the centre stone of the second course upon it. The middle diagram shows the two courses from the back. It will be seen that the middle stone of the first course does not bear upon the arch, but is supported by the two end stones let into the wall. The last diagram is a plan of the upper course at top. Slate dowels were used, and an iron bar, shown in plan under elevation a, 3 in. by ¾ in., was placed across the course tailing into the walls on each side; and two bars p p, each 2½ by ¾ in. and 12 ft. in length, tied it to the flooring of the room. This is shown likewise in the plan, the dotted lines dividing the length of flooring; d is the upper course of stones, and c one of the principal beams of the floor.
Balustrading on top of building.
The bell-turret stands 20 ft. above the roof. This is carved in oak; an elevation, section, and plan is given. Only those parts of the building are intended to be here illustrated which have some peculiarity of design or construction.
A building of this size would require about 150 working drawings to be made for it, and a considerable number to be given to show its construction.
It was completed in about two years, at an expense of 14,814l.; but this did not include the price of the warming apparatus, nor that of the lightning conductor fixed to the bell-turret.
