His suggestions will, undoubtedly, be carried out. He was
also the inventor of the "chronometric governor," an apparatus which
regulates the movements of the great transit instruments at Greenwich.
These are some of the practical benefits bestowed upon mankind by Sir
William Siemens. He did much, by stimulating men, to make science
practically useful, and has left suggestions which, if followed out with
energy and wisdom, will add greatly to the comfort of the world. He
calculated that "all the coal raised throughout the world would barely
suffice to produce the amount of power that runs to waste at Niagara
alone," and said that it would not be difficult to realize a large
proportion of this wasted power by-turbines, and to use it at greater
distances by means of dynamo-electrical machines. Myriads of future
inhabitants of America are probably to reap untold wealth and comfort
from what was said and done by Sir William Siemens.
PASTEUR.
M. Pasteur, now a member of the French Academy, after years of
scientific training and study and teaching, began a career of public
usefulness which has been a source of incalculable pecuniary profit to
his country and to the world.
He began to study the nature of fermentation; and the result of this
study made quite a revolution in the manufacture of wine and beer. He
discovered a process which took its name from him; and now
"pasteurization" is practiced on a large scale in the German breweries,
to the great improvement of fermented beverages.
