- A paper in French by Emile Wenz
In this work of 250 pages
is in the section "Variétés" a comprehensive
paper written by par Emile Wenz and plenty illustrated with
figures and pictures.
Within 21 pages E. Wenz starts
with an historical account; next he handles the captive
balloon and the kite. Then he develops the kite and continues

a long time ignored because too difficult to find in a cosmopolitan
work, is one of the most important historic document for
the story of kite aerial photography.
