Management of Light in Illumination. 137 



A dining-room illuminator of the simplest construc- 

 tion, suspended from the ceiling by a metallic rod, with 

 its six chains made of strong links of gilt wire, without 

 being enriched with cut glass, may cost from 200 to 

 250 francs. 



Those most commonly sold at Paris for lighting 

 elegant dining-rooms have had their chains richly or- 

 namented with large artificial diamonds of an oblong 

 form, called olives, made of fine cut glass, and the 

 broad hoop of gauze suspended below the dome covered 

 on the outside with cut glass arranged in festoons. 

 When ornamented in this manner and suspended by 

 pulleys, they cost from 300 to 350 francs. 



Balloon illuminators, with three or four burners, for 

 drawing-rooms, ornamented in the same manner, and 

 the ribs of their balloons covered with small diamonds 

 of cut glass, are sold at different prices according to 

 their sizes, and according to the richness and profusion 

 of their ornaments. Very elegant ones with four 

 burners may now be had for 300 francs, which two 

 years ago could not be had for less than 350 francs. 

 As their prices are lowering every day, as the number 

 of manufacturers employed in making and selling them 

 increases, I imagine they will be sold for io/. or i2/. 

 sterling in a year or two, and perhaps still lower. 



By constructing the hoop by which the reservoir is 

 suspended of strong tin, or of sheet iron painted and 

 japanned, instead of making it of brass and gilding it 

 in the fire, and by making the arrows out of strong 

 iron wire painted and japanned, instead of making them 

 of gilt brass, the price of these pendulous illuminators 

 might be greatly reduced, without making them less 

 useful or much less ornamental.
