'Doctor Ox's Experiment ' Summary

A prosperous scientist Dr. Ox comes to the authorities and offers to build a novel gas lighting system, at no cost to the town. The offer is gladly accepted. Dr. Ox and his assistant Gédéon Ygène propose to use electrolysis to separate water into hydrogen and oxygen, and pump the two gases through separate pipes to the city.

The doctor's secret plan is however to conduct a large scale experiment on the effect of oxygen on plants, animals and humans, and so he pumps an excess of the invisible and odorless gas through all lamps. The enriched air has remarkable effects on the town. It accelerates the growth of plants, and causes excitement and aggressiveness in animals and humans.

Eventually the excited citizens of Quiquendone decide to go to war against the neighboring village of Virgamen, to avenge an old offense: in 1195, a cow belonging to that town had dared to step into a Quiquendonian field and eat some mouthfuls of their grass. However, as the army was on the way to battle, an accident at Dr. Ox's plant causes oxygen and hydrogen to mix, producing a huge explosion that destroys the plant.

The story ends with the town back to its traditional slow and quiet way of life. Dr. Ox and his assistant, who were not at the plant when the accident happened, disappeared without trace.
