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.""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."
