resisting surface is moved against mass of air. Mr.
Wenham cites an experiment of Captain Dansey in which

Kites might be safer and convenient than exploring
balloons for purposes of though their employment would

ingenuity of the preceding explanations the reader may
scarcely be prepared admit Mr. Wenhams inference that

him take individual and extended flights and that success
probably only involved in question of suitable mechan-
zeal adaptations" An imitation of the birds length of wing
is out OF the question, have no means OF constructing
mechanism equally strong and light and of similar proper

carried The possible solution problem thus explained
Having remarked how thin stratum of air is displaced
beneath the wings of bird in rapid flight follows that in
order obtain the length of plane for supporting
heavy weights the surfaces may be sperposed placed in
parallel rows, with interval between them. dozen
peicans may fly above another without mutual impede

hundred weights may be supported in transverse distance
of only feet" Can any mechanism, either moved by
by inorganic motive power be constructed operate
successfully the principles thus explained? After
fully reading Mr. Wenhams paper few scientific men would
pronounce the solution of the problem impossible

opinions previously entertained by of our best mechan
icans and physicists The paper is full of close reasoning
and differs entirely from the illogical specuations often put
forth by enthusiastic projectors who work according
to methods that inevitably lead failure From certain
