The late 1860s and early 1870s are the era of the Victorian periodical. While outlets existed for the natural sciences such as Nature and Transactions of the Royal Society, we are a few years away from widespread English-language specialized journals in philosophy, economics, and so forth. Mind debuts in 1876, the Quarterly Journal of Economics (QJE) and Political Science Quarterly (PSQ) in 1886, and the Journal of the American Statistical Association in 1888.
