Fig. 5.— Interior View. 



Fig. 3 represents the end elevation, and siiows the steps ascending to the 

 entrance, the ventilators, cast-iron arches, and facia board over the plating. 

 The upright glass is 10 inches wide between the bars, and each spanrtril 

 between the arches is filled in with one piece of plate glass. The columns 

 are 6 ft. 6 in. from centre to centre, and the side elevation of the building 

 presents a series of nine arches, as shown in the exterior view. 



Fig. 4 is an angular view of the building ; both ends are alike, and both 

 sides are of the same form. On the east side, which fronts the park, the 

 masonry is partly hid by artificial rock work, and the ends and steps to the 

 entrances are adorned with ornamental plants. 



Fig. 5 is a parallel perspective representation of the interior, showing the 

 internal construction, the mode of supporting the loi gitudinal ridge and 

 valley, wooden rafters of the roof, &c. 



Construction : Mason, and Castings. — The foundations of external 

 walls and tank walls are built of solid rubble work, well bedded in mortar. 

 The curb of circular tank above the pathways, and curbs of the angular 

 tanks, are of brick, cemented. The tanks are laid with pavement and 

 covered with lead. The external walls are built of picked scappled courseil 

 wall stone, with piers battering 9 inches, and a plinth formed of two courses 

 of wallstone projecting two inches. The steps to entrances and curb walls 

 bounding them are of rubbed grit stone, and the walls are covered with 

 neatly boasted and weathered coping. The cast-iron columns are 4 inches 

 at the lower diameter of the shaft, and 3^- inches in the upper diameter. 

 The cast iron of the arches is 3^ inches wide, by 2^ inches thick, chamfered. 

 The wrought-iron beams are 5 inches by 1 inch, with tension rods I inch in 

 diameter. 



Carpenter, S(c. — The platings are 5 inches by 12 inches, the valley rafters 

 of roof, 6 inches by 4 inches; and the ridge rafters, 5 inches by 3^ inches; 

 vtith strengthening pieces over each iron beam, and sash bars 1^ inches deep. 



The ventilators are bead and flush, hung on the pivot and socket principle, 

 in rebated wooden frames. The stiles and arches of upright sashes are 

 2 inches thick, together with the doors, which are framed and panelled, and 

 furnished witli brass locks and brass butts. The pathways are laid with IJ 

 inch larch boards, J of an inch apart, radiating round the centre tank, and 

 resting upon oak sleepers 4 inches by 3 inches. The roof ventilators are 

 framed and glazed, and hinged to the rafters. The facia boards are wrought 

 and cut out, as shown on the upper part, with mouldings planted on the plating, 

 to form a cornice. The scroll is completed by painting in different shades. 

 The curbs of all the tanks are finished witii a neat rounded edge wootien 

 capping, and the circular tank is provided with a neat railing and hand rail 

 all round. The whole of the house is glazed with sheet glass 4 feet long by 

 10 inches wide, without overlaps in upright sashes, all being close jointed. 

 Every part of the masonry or brick work seen from the inside, is covered 

 with cement, and the whole of the structure, both externally and internally, 

 is thoroughly paijited in suitable and ornamental colours. The accompany- 

 ing design, described in the foregoing paragraphs, is the type of my design 

 for the building for the Great Industrial Exhibition of 1851. When the 

 large conservatory at Chatswortb was built, a great point was gained by 

 being able to have the glass manufactured in sheets of 4 feet in length ; 

 but since that period the improvements in different branches of manufac- 

 tures have enabled me to make the present Lily-house (though compara- 

 tively small) of a much more light and elegant appearance. 



It occurred to me that it only required a number of such structures as 

 the Lily-house repeated in length, width, and height, to form, with some 

 modifications, a suitable building for the exhibition of 1851. Hence arose 

 the design for that structure, and the subsequent honour conferred upon 

 me by its unqualified adoption by her Majesty's commissioners. J. Paxton
