TEN BRITISH PHYSICISTS

few not conferred; he is still open, I believe, to receive some distinguished mark of recognition from the geologists.

Lord Kelvin has been twice married, but there is no direct heir to inherit either his genius or title. Notwithstanding the fact that he has long been the acknowledged leader of science in Great Britain, and indeed in Europe, his disposition has remained simple and kindly. A multitude of honors, and great fame and power has not spoiled the grandson of the small Irish farmer. He is still active in the production of scientific papers, and although now nearly 78 years of age is making preparations to again cross that ocean which has been the scene of so many of his exploits, and which is now much more safely navigated through the instrumentality of his inventions.[1]

  1. Lord Kelvin died on December 17, 1907, in the 84th year of his age. His activity in scientific discussions did not diminish with age. He revised the lectures on the wave-theory of light which he had delivered at Johns Hopkins University and published them in 1904. In that year also he was elected Chancellor of the University of Glasgow. He continued to take an active part in the work of scientific societies; only a few months before his death he delivered at the meeting of the British Association a long and searching address on the electronic theory of matter. He was buried in Westminster Abbey a few feet south of the grave of Newton.—Editors.
