The building itself, the well-known Palais d'Industrie in the 

 Champs Elysees, is a Crystal Palace, and was built for the 

 first French Exhibition of the Industry of all Nations. It is 

 not near so large as the Sydenham Crystal Palace, but is per- 

 haps 200 yards long and 80 broad — a very good size for an 

 Exhibition, as it is big enough to hold all that one can see in 

 reasonable time, and is not so large as to fatigue one with the 

 mere physical labour of walking over it. 



The interior presented a bright and animated appearance, 

 even in the daytime, when there were not many electric 'lights 

 to be seen, and was still more striking with the blaze of the 

 lamps at night. It was tastefully decorated. The ground floor 

 was parcelled out among the different nations, and could all be 

 surveyed at a glance by a spectator in the gallery. There were 

 electric lamps, dynamo machines, telephones, telegraphs of 

 every form, some of them printing messages by putting down 

 keys like the keys of a piano, some of them producing copies 

 of pictures which were gradually built up line by line like 

 a piece of Berlin wool work. There were sewing machines 

 and weaving machines driven by electricity, and two great 

 pumps pouring fourth immense sheets of a bright red liquid 

 in a manner calculated to attract the attention of all beholders, 

 also driven by electricity. There were baths with spoons and 

 other articles suspended in them, undergoing the processes of 

 electro-plating and gilding ; and large plates of pure copper, 

 larger and thicker than any of the flagstones of our pavements, 

 which had been deposited by the electro-metallurgical machine 

 of Siemens. There were the newest and best forms of friction 

 machines, and improvements on the Holtz, which render it in- 

 dependent of frictional aid at starting. There was the gigantic 

 Ruhmkorff coil about six feet long, made for Mr. Spottiswoode, 

 by Apps ; a specimen of Sir Wm. Thomson's Siphon Recorder, 

 as well as of his large Absolute Electrometer ; cable-laying 

 apparatus, and a beautiful model of Messrs. Siemens' cable-laying 

 steamer, the " Faraday." There was the Phonograph, and the 

 still newer invention, the Photophone ; while among antiqui- 

 ties there were gigantic electrical machines and Leyden jars
