Fifth Edition, with Additions. — Albany: J. Munsell, 1876. — 263 p.
The facts embraced in the following pages have been gathered from so many sources, that it would materially encumber the work to give authorities. The valuable essay of Breitkopf, 1 published in 1784, and the interesting history of Matthias Koops,2 who made extensive experiments in England in the beginning of the present century, have furnished numerous data. The Jury Report of the London Industrial Exhibition has been used to a considerable extent for more modern statistics of European countries. For the remainder, almost every available work has been consulted in English, French, German, and Nederdutch, and the newspapers. Upon the accuracy of the figures in the statistics here given it is impossible implicitly to rely, especially upon such as have been gathered from the newspapers, where careful comparison is seldom given. The compiler has availed himself of whatever came under his observation that had the appearance of authenticity, but has not always had opportunity to verify dates and quantities.
