mental physics, entitled "The New Physics," in which modern views of the great subject of physics are inculcated through the means of elementary laboratory work. He has also contributed various essays to the "Atlantic Monthly," one of which, entitled "The Dream of Life," is an argument, ad hominem, in favor of the option of scientific studies by students who desire to enter the university without Greek. His contributions to "The Popular Science Monthly" treat of various subjects, among which may be mentioned: *' Science from the Pulpit"; "On the Teaching of Physics in the Secondary Schools"; "On the Use of Electric Lights for Steamships." In the latter paper, Professor Trowbridge advocated the use of the electric light for a head-light. Practical navigators, however, assert that such light is not to be recommended, for its dazzling glare confuses the eyes of the steersmen of approaching vessels.
His address before the American Association for the Advancement of Science was upon the question, "What is Electricity?" and, in reading it, one can discover the directions in which the author has investigated.[1] The life of an investigator is an arduous one; but few of the ideas which take months to investigate give what are called positive results. Faraday, it is true, gave to the world the history of both his successful experiments and his unsuccessful ones. It is not the custom, however, of later physicists to do this. Scientific literature is already voluminous, and this reticence of scientific men is perhaps a boon to those who desire to look up any subject. With the increased facilities which the new laboratory at Cambridge will give, Professor Trowbridge enters upon a fresh scientific career in the prime of life, and there is reason to hope that many positive results to science will accrue from his future labors.
He is a member of the American Academy of Arts and Sciences, of which he was secretary from 1879 to 1884; he is also a member of the National Academy of Sciences. He is one of the editors of the "American Journal of Science." He was a member of the International Congress of Electricians which met in Paris, in 1883, and of the United States Congress of Electricians which met in Philadelphia last October. He was also one of the Vice-Presidents of the American Association for the Advancement of Science for 1884, at the Philadelphia meeting.
