"Talus. The huckle-bones of sheep and goats were used to play with from the earliest times, principally by women and children, occasionally by old men. The following cut, taken from an ancient painting, represents a woman, who, having thrown the bones upwards into the air, has caught three of them on the back of her hand. When the sides of the bone were marked with different values, the game became one of chance. The two ends were left blank, because the bone could not rest upon either of them on account of its curvature. The four remaining sides were marked with numbers 1, 3, 4, 5; 1 and 6 being on two opposite sides, and 3 and 4 on the other two opposite sides. Two persons played together at this game, using four bones, which they threw up into the air, or emptied out of a dice-box, and observing the numbers on the uppermost sides. " &mdash Smith; 1873

"The Furies are generally represented with a scourge, with which to punish the wicked in Tartarus. It probably was supposed to resemble the whip used for punishing slaves, which was a dreaedful instrument, knotted with bones or heavy indented circles of bronze, or terminated by hooks, in which latter case it was aptly denominated a scorpion." — Anthon, 1891

Interior of the ear. There is external to the head a wide-mouthed tube, or ear-trumpet (a), for catching and concentrating the waves of sound. It is movable in many beings, so that they can direct it to the place from which the sound comes. The sound concentrated at the bottom of the ear-tube falls upon a membrane stretched across the channel, like the parchment of an ordinary drum, over the space called the <em>tympanum</em>, or <em>drum of the ear</em> (b), and causes the membrane to vibrate. That its motion may be free, the air contained within the drum has free communication with the external air by the open passage (f), called the <em>eustachian tube</em>, leading to the back of the mouth. A degree of deafness ensues when this tube is obstructed, as in a cold; and a crack, or sudden noise, with immediate return of natural hearing, is, generally experienced when, in the effort of sneezing or otherwise, the obstruction is removed. The vibrations of the membrane of the drum are conveyed further inwards, through the cavity of the drum, by a chain of four bones (not here represented on account of their minuteness), reaching from the centre of the membrane to the <em>oval door</em> or <em>window</em>, leading into the labyrinth (e). The labyrinth, or complex inner compartment of the ear, over which the nerve of hearing is spread as a lining, is full of watery fluid; and, therefore, by the law of fluid pressure, when the force of the moving membrane of the drum, acting through the chain of bones, is made to compress the water, the pressure is felt instantly over the whole cavity. The labyrinth consists of the <em>vestibule</em> (e), the three <em>semicircular canals</em> (c), imbedded in the hard bone, and a winding cavity, called the <em>cochlea</em> (d), like that of a snail-shell, in which fibres, stretched across like harp-strings, constitute the <em>lyra</em>.
