Subsequent investigations seemed only to render "confusion worse confounded." They appeared to justify the dreams of the alchemists of old, not only regarding the transmutation of metals but also respecting the elixir of life. For was not this apparently absurd idea vindicated by the observed curative properties--bordering almost on the miraculous--this marvelous element was reputed to possess! Its virtues, it was averred, transcended the fabled properties of the famous red tincture and the philosopher's stone combined, and many were prepared to find in it a panacea for the most distressing of human ailments, from lupus and rodent ulcer to cancer and other frightful forms of morbid degeneration.[161] And the end is not yet. Continued investigations, made in all parts of the world since the discovery of radium by the Curies, have but emphasized its mysterious properties, and compelled a revision of many of our most cherished theories in chemistry, physics and astronomy. No one single discovery, not even Pasteur's far-reaching discovery of microbic life, it may safely be asserted, has ever been more subversive of long-accepted views in certain domains of science, or given rise to more perplexing problems regarding matters which were previously thought to be thoroughly understood. Never in the entire history of science have the results of a woman's scientific researches been so stupendous or so revolutionary. And never has any one achievement in science reflected more glory on womankind than that which is so largely due to the genius and the perseverance of Mme. Curie. After their startling discovery, honors and tributes to their genius came in rapid succession to the gifted couple. On the recommendation of the venerable British savant, Lord Kelvin, they were awarded the Davy gold medal by the Royal Society. Shortly after this they shared with M. H. Becquerel in the Nobel prize for physics bestowed on them by Sweden. Then came laggard France with its decoration of the Legion of Honor. But it was offered only to the man. There was nothing for the woman. Pierre Curie showed his spirit and chivalry by declining to accept the proffered honor unless his wife could share it with him. His answer was simple, but its meaning could not be mistaken. "This decoration," he said, "has no bearing on my work."[162] Shortly after her husband's death Mme. Curie was appointed as his successor as special lecturer in the Sorbonne. This was the first time that this conservative old university ever invited a woman to a full professorship. But she soon showed that she was thoroughly competent to fill the position with honor and eclat. She has the elite of society and the world's most noted men of science among her auditors. The crowned heads of the Old World eagerly seek an opportunity to witness her experiments and hear her discourse on what is by all odds the most marvelous element in nature.
