Rh Dr. Bartlett claims that ozone possesses very important curative properties, has employed it successfully in numerous cases of asthma, hay-fever, typhoid fever, scarlatina, diphtheria, puerperal fever, erysipelas, etc. He predicts that its introduction will work great changes in the medical treatment of zymotic or malarial diseases. While making due allowance for the enthusiasm of an inventor, it must be admitted that Dr. Bartlett has produced a machine which does well the work for which it was intended.

Science in the United States.—Sir William Thomson, in the presidential address to the Physical Section of the British Association, spoke as follows of the work of some of our American scientific men:

The French Association.—The fifth session of the French Association for the Advancement of Science was opened at Clermont-Ferrand, on the 18th of August. In the opening address, the president, M. J. Dumas, sketched the history of the British Association, pointing out the great services rendered by that body in popularizing science. Similar results are to be expected from the French Association. Of the place occupied by science in modern life, he said: "Natural science is no longer content with the contemplative attitude which sufficed for Newton and Laplace. Science is now mixed up with all the personal acts of our existence; she interferes in all measures of public interest; industry owes to her its immense prosperity; agriculture is regenerated under her fostering care; commerce is forced to take her discoveries into account; the art of war has been transformed by her; politics is bound to admit her into its councils for the government of states. How could it be otherwise? Have not mechanics, physics, chemistry, the natural sciences, become intelligent and necessary agents for the creation of wealth by labor? If comfort is more universal, the life of man more prolonged, wealth better distributed, houses more commodious, furniture and clothing cheaper, the soldier better armed, the finances of the state more prosperous, is it not to the sciences that all this progress is due?... Whether we wish it or not, we must needs accept Science as a companion, to possess her or to be possessed by her. If you are ignorant, you are her slave; if you are skilled, she obeys you. The future belongs to science; unhappy are they who shut their eyes to this truth."

Japanese Metallurgy.—A writer in the Japan Mail describes as follows the Japanese method of obtaining mercury from its sulphide (cinnabar): The cinnabar is first
