1. Fibre Suspension

   Suspension, as of a galvanometer needle, by a vertical or hanging fibre of silk or cocoon fibre, or a quartz fibre. (See Quartz.) This suspension, while the most delicate and reliable known, is very subject to disturbance and exacts accurate levelling of the instrument. Fibre suspension is always characterized by a restitutive force. Pivot suspension, q. v., on the other hand, has no such force.
