Book Description
Excerpt from Smithsonian Miscellaneous Collections, Vol. 2 The following Report has been prepared under the direction and at the expense of the Smithsonian Insti tution, from articles in various Journals of Science and the Arts, published during the last few years, in the English, French, and German languages; and, among these, we acknowledge our indebtedness chiefly to the Chemical Gazette, issued in London, and to the excel lent Report ou Practical Chemistry, by Dr. Eisner, of Berlin. We have freely exercised discrimination in the selection of subjects, and have omitted much that we found on Applied Chemistry, because novel views need in many cases further confirmation to render them re liable in practice, and, if presented too early to the ar tisan, may be productive of more evil than good. We have kept in View the benefit of the practical man, the manufacturer or maker, and, while we have not avoided scientific terms when more convenient, we have gene rally used modes of description intelligible to every one. American Patents relating to the Chemical Arts have been generally omitted, because they are published annually in the Reports of the Patent Office, which are widely distributed throughout the United States, and therefore accessible to all. We have confined ourselves to such foreign improve ments in the Chemical Arts, whether patented or not, as we believed the American artisan might avail him self of, frequently offering critical remarks on them, and sometime's pointing out where improvements were likely to be made.
