Review
“There
is then no panspermy such as that which Charles Bonnet has invented, nor that
which Spallanzani and Pasteur (after me) had admitted. In short. There are no
pre-existing germs. At each period, as in our days, and in each place there
exist in the surrounding air only the microzymas of former beings which had
disappeared and are disappearing with the things which the wind scatters in
it.â€
