This device was apparently capable of crushing flints, bones, and coprolites as easily as barley and wheat into a fine powder. According to the accompanying article, it "also splits beans, bruises oats, crushes linseed, &c. Its action consists in two plates running in the same direction, and at the same velocity, but not on the same centre; hence it is sometimes called the Eccentric Mill. We have engraved a section through the grinding plates, to illustrate more clearly the principle of its action" (31).
