This periodical was started (in 1872) to promote the diffusion of valuable scientific knowledge, in a readable and attractive form, among all classes of the community, and has thus far met a want supplied by no other magazine in the United States. Containing instructive and interesting articles and abstracts of articles, original, selected, translated, and illustrated, from the pens of the leading scientific men of different countries; accounts of important scientific discoveries, the application of science to the practical arts, and the latest views put forth concerning natural phenomena, have been given by _savants_ of the highest authority. Prominent attention has been also devoted to those various sciences which help to a better understanding of the nature of man, to the bearings of science upon the questions of society and government, to scientific education, and to the conflicts which spring from the progressive nature of scientific knowledge. THE POPULAR SCIENCE MONTHLY is published monthly in a large octavo, handsomely printed on clear type, and, when the subjects admit, fully illustrated. TERMS: $5.00 per annum, or Fifty Cents per Number. Postage prepaid to all Subscribers in the United States. * * * * * THE ART JOURNAL: _An International Gallery of Engravings_, BY DISTINGUISHED ARTISTS OF EUROPE AND AMERICA; WITH ILLUSTRATED PAPERS IN THE VARIOUS BRANCHES OF ART.
