Palmer's patent "consists in the application, to common sand, flint, or emery paper, of boiled linseed-oil or other equivalent fatty substance, in such a manner that after the paper has absorbed the oil, and said oil has become thoroughly dry and fixed in the pores of the paper, an article is obtained of much greater toughness and firmness than sand-paper made in the usual manner, and my sand, flint, or emery paper is more durable and economical than any other similar article."
