On placing this between a light and your sun, and moving it towards that side to which the convexity of the spiral is turned, the opening will give, on the image of the sun’s rays or jets of fire, the appearance of fire continuously flowing from the centre to the circumference.
THE SULTAN’S SUMMER PALACE ILLUMINATED.
Take a print of an Oriental palace, and colour it properly. On the back paste paper to make it but partially transparent. With differently sized points prick small holes in the places, and on the lines where lamps and lanterns are generally placed, as along the sides of windows, cornices, arches of doors, balustrades, and as if suspended from trees. The greater the supposed distance of these architectural and decorative features, the smaller and closer these punctures must be. With large punches cut out the stronger lights, as of Bengal fires in pots, and so forth.
Cut out the panes of some of the windows, and paste at the back gelatine paper of green or red colour, as if they were curtains within an illuminated room.
Place the print thus prepared in the front of a box representing a miniature theatre, strongly lighted from the back, and look at it through a convex glass of a rather long focus.
There may be added some pieces of Chinese or artificial fireworks, moved by clockwork.
