mystery, that disembowelled intelligence, Henry Cavendish,
towards the end of the eighteenth century. So far as he was
concerned the work was admirably done. He separated all the known
ingredients of the air with a precision altogether remarkable; he
even put it upon record that he had some doubt about the purity
of the nitrogen. For more than a hundred years his determination
was repeated by chemists all the world over, his apparatus was
treasured in London, he became, as they used to say, 'classic,'
and always, at every one of the innumerable repetitions of his
experiment, that sly element argon was hiding among the nitrogen
(and with a little helium and traces of other substances, and
indeed all the hints that might have led to the new departures of
the twentieth-century chemistry), and every time it slipped
unobserved through the professorial fingers that repeated his
procedure.

Is it any wonder then with this margin of inaccuracy, that up to
the very dawn of the twentieth-century scientific discovery was
still rather a procession of happy accidents than an orderly
conquest of nature?

Yet the spirit of seeking was spreading steadily through the
world. Even the schoolmaster could not check it. For the mere
handful who grew up to feel wonder and curiosity about the
secrets of nature in the nineteenth century, there were now, at
the beginning of the twentieth, myriads escaping from the
limitations of intellectual routine and the habitual life, in
Europe, in America, North and South, in Japan, in China, and all
about the world.

It was in 1910 that the parents of young Holsten, who was to be
called by a whole generation of scientific men, 'the greatest of
European chemists,' were staying in a villa near Santo Domenico,
between Fiesole and Florence. He was then only fifteen, but he
was already distinguished as a mathematician and possessed by a
savage appetite to understand. He had been particularly attracted
by the mystery of phosphorescence and its apparent unrelatedness
to every other source of light. He was to tell afterwards in his
reminiscences how he watched the fireflies drifting and glowing
among the dark trees in the garden of the villa under the warm
blue night sky of Italy; how he caught and kept them in cages,
dissected them, first studying the general anatomy of insects
very elaborately, and how he began to experiment with the effect
of various gases and varying temperature upon their light. Then
the chance present of a little scientific toy invented by Sir
William Crookes, a toy called the spinthariscope, on which radium
particles impinge upon sulphide of zinc and make it luminous,
induced him to associate the two sets of phenomena. It was a
happy association for his inquiries. It was a rare and fortunate
thing, too, that any one with the mathematical gift should have
