Claude Monet, the artistic descendant of Claude Lorrain, Turner, and Monticelli, has had the merit and the originality of opening a new road to landscape painting by deducing scientific statements from the study of the laws of light. His work is a magnificent verification of the optical discoveries made by Helmholtz and Chevreul.
References which would be pleasant to such of them as still live are made to Humboldt, Biot, Dumas, Chevreul, Magnus, and Arago. Accident brought these names prominently forward; but many others would be required to complete his list of continental friends. He prized the love and sympathy of men prized it almost more than the renown which his science brought him.
This acid, whose singular influence on cell life has been shown by M. Dumas, is so slightly acid that it is alkaline to certain test papers, as was long ago shown by M. Chevreul, besides this it has no odor like carbolic acid, which odor often disturbs the sick.
Claude Monet has been thus far the most successful practitioner of impressionism; this by reason of his extraordinary analytical power of vision and native genius rather than the researches of Helmholtz, Chevreul, and Rood. They gave him his scientific formulas after he had worked out the problems. He studied Turner in London, 1870; then his manner changed.
Charles gave a literary outlet to his passion for hunting; he wrote a little treatise entitled La Chasse royale, which was not published until 1625, and of which M. Henry Chevreul brought out, in 1857, a charming and very correct edition. Charles IX. dedicated it to his lieutenant of the hunt, Mesnil, in terms of such modest and affectionate simplicity that they deserve to be kept in remembrance.
The author says: "I repeat in this pamphlet the principal facts put forth in the notes issued by me, and in the reports furnished by Mr. Chevreul to the Academy of Science, from 1853 up to 1860."
The best-known modern treatise on the divining-rod is that of M. Chevreul, 'La Baguette Divinatoire' . We have also 'L'Histoire du Merveilleux dans les Temps Modernes, by M. Figuier . In 1781 Thouvenel published his 600 experiments with Bleton and others; and Hegel refers to Amoretti's collection of hundreds of cases.
Among them were Elie de Beaumont, the geologist; Milne-Edwards, the zoölogist; and Chevreul, the chemist. I was surprised to learn that the latter was in his eighty-fifth year; he seemed a man of seventy or less, mentally and physically. Yet we little thought that he would be the longest-lived man of equal eminence that our age has known.
I can paint pictures on the sky. I can produce blazing symphonies. I will prove to you that colour is also music. This sounds as if I were a victim to that lesion of the brain called 'coloured-audition. Perhaps! Not Helmholtz or Chevreul can tell me anything new in the science of optics.
Chevreul, the great French scientist, whose untiring labors in the realm of color have so enriched the world, was busy, keen and active when Death called him, at the age of 103. These men did not fear age; these few names from the great muster-roll of the famous ones who defied the years, should be voices of hope and heartening to every individual whose courage and confidence is weak.
