 2.  Com. (a) A tariff or duty on goods, etc. [Obs.] (b) Any charge in addition to the regular charge for freight of goods shipped. (c) A contribution to a loss or charge which has been imposed upon one of several for the general benefit; damage done by sea perils.

 General average, a contribution made, by all parties concerned in a sea adventure, toward a loss occasioned by the voluntary sacrifice of the property of some of the parties in interest for the benefit of all. It is called general average, because it falls upon the gross amount of ship, cargo, and freight at risk and saved by the sacrifice. --Kent.
 Particular average signifies the damage or partial loss happening to the ship, or cargo, or freight, in consequence of some fortuitous or unavoidable accident; and it is borne by the individual owners of the articles damaged, or by their insurers.
 Petty averages are sundry small charges, which occur regularly, and are necessarily defrayed by the master in the usual course of a voyage; such as port charges, common pilotage, and the like, which formerly were, and in some cases still are, borne partly by the ship and partly by the cargo. In the clause commonly found in bills of lading, “primage and average accustomed,” average means a kind of composition established by usage for such charges, which were formerly assessed by way of average. --Arnould.  --Abbott. --Phillips.

 4. Any medial estimate or general statement derived from a comparison of diverse specific cases; a medium or usual size, quantity, quality, rate, etc. “The average of sensations.”
