SMALL CAUSES; GREAT EFFECTS
extraordinary thing is that a minute quantity of platinum
is able to bring about the combination of very large
quantities of hydrogen and oxygen. One experiment has
been recorded in which, under the influence of the
of an ounce of platinum, over two gallons of
a mixture of hydrogen and oxygen disappeared in seven-
teen days. And the platinum was as active at the
end of this period as at the beginning!
There are numerous catalytic agents in addition to
those which are used in the laboratory or the factory.
Our bodies are the scene of many chemical changes which
are promoted and accelerated by the influence of certain
agents called enzymes, the exact nature of which is not
yet known. These substances play an important part
as catalytic agents, notably in the processes of digestion,
but an excursion into this interesting field would take
us too far. Perhaps enough has been said to convince
the reader that in chemistry, at least, much that is
apparently insignificant is of the greatest value and
importance.
