Despite the criticism, Pouchet published his famous book "Hétérogénie ou traité de la génération spontanée" in 1859, which publicized his support of spontaneous generation. He claimed that his views of spontaneous generation were not like that of the older views of spontaneous generation that were labeled as atheistic, but were rather in agreement with the orthodox scientific and religious beliefs of the time. Pouchet claimed that it was the eggs of adult organisms that were spontaneously generated, not the adult organisms themselves.
