Experiments by Stringfellow.
The next man to test an apparatus with superposed surfaces was Mr.
Stringfellow, who, becoming much impressed with Mr. Wenham's proposal,
produced a largish model at the exhibition of the Aeronautical Society
in 1868. It consisted of three superposed surfaces aggregating
One of the First Hargrave Kites.
