A Voyage in a Balloon

In this early work we see the ingredients of Verne's later Voyages Extraordinaires; characters brought or thrown together on a journey to afar; introduction of new characters part way through the story; careful scientific explanation of critical events (the ascension, filling the balloon, rising and falling, ballast); use of dialogue to convey scientific information (the history of ballooning); use of scientific instruments (barometer, compass); chapter heads to presage the story; escapes from perilous events caused by scientific or natural catastrophes.
