I wanted to 6nd out the necessary In
crease Of weight required to sink the
Nautilus I had only to calculate the
reduction Of volume that sea water
acquires according to the depth"
That Is evident"
Now. II water Is not absolutely in
compressible. II Is at least capa BILE OF
very slight compression. Indeed. aft.
er the most recent calculations this
reduction is only 0!OOO43G OF nm atmos-
phere for each thirty feet Of depth. II

two inclined planes fastened to its

the Nautilus TO rise vertically like

Bravo. captain! But how can the
steersman follow the route In the mid

-The steersman Is placed In glazed
box that is raised above the hull Of the
Nautilus and furnished with lenses"
Are these lenses capable of resisting
