When thrown from the hand with a quick rotary motion, it describes very remarkable curves, according to the shape of the instrument and the manner of throwing it, often moving nearly horizontally a long distance, then curving upward to a considerable height, and finally taking a retrograde direction, so as to fall near the place from which it was thrown, or even far in the rear of it.
