The object of this invention is the construction of an aeronautic apparatus based upon the principle termed the "heavier than air principle" in contradistinction to the principle which consists in giving to the balloon a weight less than that of the air displaced, and in fact my aeronautic apparatus presents the double characteristic of being provided on the one hand with balloons inflated with a gas which is lighter than air, and seeing that, even in spite of this partial lightening, it has still a total weight greater than, or at least equal to, that of the air displaced, of being provided, on the other hand with rotating helices which produce its ascent.

Refers to a French patent filed 21 March 1898. Resembled by Patent US-1900-648634 and might be the 'same invention' to some degree, but presented differently.
