itself ; a double nervous system was evolved ; jaws were 
formed ; a swim-bladder made its appearance ; and two 
pairs of legs were developed ; and so was produced — 
Step 11. The mud-fish^ somewhat like the present salamander, 
and this was effected by the adaptation of life on land. 
The swim-bladder was now made into an air-breathing 
lung, and thus was produced — 
Step 12. Grilled amphibiums, such as are met with in the pre- 
sent day. In the course of ages these creatures were 
evolved into — 
Step 13. Tailed amphibians. These creatures accustomed 
themselves to breathe only by means of gills in the early 
stages of their life, and in the latter stages through lungs. 
In the course of ages these gave birth to — 
Step 14. The primaeval amniota. These were evolved out of 
an unhioiun tailed amphibian, by the loss of gills. 
Strange to say, the organs of tears were now developed. 
How wonderful ! After many ages these creatures were 
evolved into animals with hairs and mammary glands, 
and so — 
Step 15. Primary mammals, closely related to the ornitho- 
rhynchus of the present day, were produced. By degrees 
these monotremata produced — 
Step 16. Pouched animals. In the course of time one of 
these marsupial creatures produced — 
Step 17. Semi-apes, which, in the lapse of ages, produced the 
animals of the narrow-nosed monkey tribe, and out of 
these were evolved — 
Step 18. The tailed apes of the Hew World, which, in the 
course of ages, produced — 
Step 19. The man-like apes (anthropoides) which, in the 
process of time, lost their tails and a portion of the 
hairy covering on the back. Poor things ! How much 
inconvenience they must have suffered on this account ! 
When speaking of these creatures the professor says, — 
There do not exist direct human ancestors among the anthro- 
poides of the present day, hut they certainly existed among 
the unhnoim extinct human apes of the Miocene period 
We beg the reader to mark this assumption, — they cer- 
tainly existed — that is, they existed in the professoPs 
imagination. In the face of this assumption, however. 
Professor Haeckel continues his steps in the development 
of man as if it were a thing of certainty, and states that 
in the process of time these man-like apes produced — 
Step 20. Ape-like men. In the course of time out of these 
were evolved —
