ing | have found a curious similarity
about the two problems of submarine
and aerial navigation. | also have
found a principle which controls both
namely, that the center of gravity
always must be- exactly under the cen
ter of support, and the thrust always
must be exactly opposite the center of
resistance. The principle is the same
in air az in water. the only difference
is the greater density of the water.
''Only in case speed is required
will there be need for exertion in fly
ing. There will be no mechanism
for supplying great power. This

Descending will be accomplished at
