 2. That which guides, points out, informs, or directs; a pointer or a hand that directs to anything, as the hand of a watch, a movable finger or other form of pointer on a gauge, scale, or other graduated instrument.  In printing, a sign [☞] (called also fist) used to direct particular attention to a note or paragraph.
 3. A table for facilitating reference to topics, names, and the like, in a book, usually giving the page on which a particular word or topic may be found; -- usually alphabetical in arrangement, and printed at the end of the volume.  Typically found only in non-fiction books.

 5. Anat. The second finger, that next to the pollex (thumb), in the manus, or hand; the forefinger; index finger.
 6. Math. The figure or letter which shows the power or root of a quantity; the exponent. [In this sense the plural is always indices.]
 7. The ratio, or formula expressing the ratio, of one dimension of a thing to another dimension; as, the vertical index of the cranium.
 Index error, the error in the reading of a mathematical instrument arising from the zero of the index not being in complete adjustment with that of the limb, or with its theoretically perfect position in the instrument; a correction to be applied to the instrument readings equal to the error of the zero adjustment.
