INVISIBLE AEROPLANE.

A GERMAN BRAG. Tho "Cologne Gazette.'' " 1»® Matin." has "been bragging of a new aeroplane that the Germans have just invented. It is called an '' invisible aeroplane. The canvas which covers the* wings is replaced by a transparent substance, " oellon," tho same as wJiat is used in place of glass in automobiles. It is a chemical combination of celluloid and acetic acid. The " eel lon " is very flexible, it. does not break, it "will not go on fire, and is in no danger from tho petrol. It is practically invisible, we are assured, at a distance higher than 900 metres, and it cannot bo distinguished by the naked eye at a height of 1800 metres.

Albert Moreau, who has since been "killed iu an aeroplane accident. It was examined, but the transparent material was at that time tho light not to liavo a sufficiency of resisting power. Since then experiments have been carried on with this "cellon" substance, which is simply the acetate of celluloid, which is largely used in the manufacture of kinomatograph films to render them uninflammable. The aeroplane department of the army has been experimenting with the. material to teat th<* possibilities of it for .aeroplane j
