Such an unusual genius was Professor Robert Ogden Doremus, whose enthusiasm was only matched by his modesty. In studying what he accomplished, I wonder whether he was not sent from the central yet universal "powers that be" to give us answers to some of the riddles of life; or had he visited so many planets further advanced than our own--for as Jean Paul Richter wrote "There is no end"--that he had learned that the supposedly impossible could be done. He assisted John W. Draper in taking the first photograph of the human face ever made. Science with him was never opposed to religion. His moving pictures and spectral analysis were almost miracles at that time. He delighted to show how the earth in forming was flattened at the poles, and he would illustrate the growth of the rings of Saturn. As a lecturer he was a star, the only chemist and scientist to offer experiments. His lectures were always attended by crowds of admirers. As a toxicologist he was marvellous in his accuracy; no poisoner could escape his exact analysis. His compressed cartridges, made waterproof and coated with collodion, were used in the blasting operations at the Mont Cenis tunnel through eight miles of otherwise impenetrable stone, solid Alpine rock, between France and Italy. When the obelisk in Central Park showed signs of serious decay, he saved the hieroglyphics by ironing it with melted parafine. He makes us think of the juggler who can keep a dozen balls in the air as if it were an easy trick, never dropping one. [Illustration: PROFESSOR R. OGDEN DOREMUS]
