In the Days of the Comet illustrated H G Wells

In the Days of the Comet (1906) is a science fiction novel by H. G. Wells in which humanity is "exalted" when a comet causes "the nitrogen of the air, the old azote," to "change out of itself" and become "a respirable gas, differing indeed from oxygen, but helping and sustaining its action, a bath of strength and healing for nerve and brain."[2] The result: "The great Change has come for evermore, happiness and beauty are our atmosphere, there is peace on earth and good will to all men."[3]
