As a result of this movement, which has been of great benefit in stimulating the growth of science in the country, many new journals of specialized character have come into existence from time to time. Further localization and specialization of scientific publication have resulted from the increased activity of scientific societies and academies at numerous centers and the springing into existence thereby of new organs of publication through them, as also through certain of the Government Departments, the Carnegie Institution, and certain universities and museums. As bearing upon this subject, the following list of the more prominent scientific periodicals started in this country since 1867 is not without interest: 1867– . American Naturalist. 1875– .
