The Projectile-Carriage
- Ardan suggests changing the shape of the projectile from a sphere to a conic, bullet-like shape. This new capsule arrives in mid-November.
- The interior is rather nice—it has light, heat, and food—and Ardan even figures out a way to produce oxygen by evaporating "Chlorate of potash" (23.24).
- Time for another test. J.T. Maston (super-bummed that he can't take the trip, too) volunteers to be locked in the capsule for eight full days to see if everything works.
- To everyone's surprise, Maston "had grown fat" (23.43) by the time those eight days are up.
