ORIGIN OF LIFE. 61 
9. The Order observable in the 
succession of living things which 
appear in very many organic infu- 
sions :—1I. Bacteria; 2, Monads 
and Amceba, or Fungus Germs ; 
3. Ciliated Infusoria ; 4. Rotifers. 
10. The wide diffusion and con- 
stant association of certain organ- 
isms (Rotifers, Sloths, and Nema- 
toids) which multiply by very large 
and well-known germs. 
11, Our power of determining 
the presence of some of the higher 
Fungi (Mushrooms), and of Nema- 
oids, at will, in certain organic 
mixtures. 
12. The wide diffusion and 
numerical abundance of Desmids 
and Diatoms. (Vol. II, pp. 420, 
435—455.) 
13. The: incoustancy of par- 
ticular species of lower organisms 
in the same habitats from year to 
year ; and the sudden appearance 
of other organisms in enormous 
numbers in situations where they 
had not previously existed. 
14. The uniform association of 
certain other organisms with their 
accustomed matrices, ag., of par- 
ticular kinds of Mould with par- 
ticular organic substances, and the 
almost invariable association of 
Euglenze with Rotifers. 
15. The observed relations be- 
tween size of matrix and grade of 
ance as bodies of comparatively 
large dimensions. 
g. No reasonable explanation of 
this order in accordance with the 
hypothesis of Homogenesis, and 
with facts known concerning the 
distribution of the germs of such 
organisms. (Vol. II., pp. 297— 
306, 502-535.) 
10, These facts, quite irrecon- 
cilable with the ascertained absence 
of such germs or organisms from 
the atmosphere, and an exclusive 
doctrine of Homogenesis. (Vol. 
IL, pp. 535—538.) 
11. These results seemingly 
inexplicable from the point of 
view of Panspermism and Homo- 
genesis, (Vol. IL, pp. 433, 537 
note.) 
12. Inexplicable by what we 
know concerning their absence 
from the atmosphere and their 
modes of multiplication. 
13. Facts either incapable of 
being explained by, or directly op- 
posed to, the hypothesis of Homo- 
genesis and Panspermism. (Vol. 
IL, pp. 535s 454) 
14. The uniformity of such 
associations quite incompatible 
with known facts concerning the 
prevalence of germs of Fungi, 
Euglenz and Rotifers in the air. 
(Vol. IL, pp. 302 zote; 535, 508 
note.) 
15. The impossibility of ex- 
plaining away all these observa-
