“eries “cuckoo!” and perhaps shows the phases of 
the moon. When the clock is wound up, all the 
_ phenomena which it exhibits are potentially con- 
' tained in its mechanism, and a clever clockmaker 
could predict all it will do after an examination of 
its structure. 
If the evolution theory is correct, the mole- 
cular structure of the cosmic gas stands in 
the same relation to the phenomena of the 
world as the structure of the clock to its pheno- 
mena. 
Now let us suppose a death-watch, living in the 
clock-case, to be a learned and intelligent student 
of its works. He might say, “I find here nothing 
but matter and force and pure mechanism from 
beginning to end,” and he would be quite right. 
But if he drew the conclusion that the clock was 
not contrived for a purpose, he would be quite 
wrong. On the other hand, imagine another 
death-watch of a different turn of mind. He, 
listening to the monotonous “tick! tick!” so 
exactly like his own, might arrive at the conclusion 
that the clock was itself a monstrous sort of 
death-watch, and that its final cause and purpose 
was to tick, How easy to point to the clear 
_ relation of the whole mechanism to the pendulum, 
to the fact that the one thing the clock did always 
and without intermission was to tick, and that all 
- the rest of its phenomena were intermittent and 
subordinate to ticking! For all this, it is certain
