Occasionally a plume of ostrich feathers is found enclosed in a "case," that is, wrapped about the lower part as if it were a bouquet, and this form is the more usual in Germany. In German heraldry these plumes are constantly met with in the colours of the arms, or charged with the whole or a part of the device upon the shield. It is not a common practice in this country, but an instance of it will be found in the arms of Lord Waldegrave: "Per pale argent and gules. Crest: out of a ducal coronet or a plume of five ostrich feathers, the first two argent, the third per pale argent and gules, and the last two gules." {253} CHAPTER XV FISH Heraldry has a system of "natural" history all its very own, and included in the comprehensive heraldic term of fish are dolphins, whales, and other creatures. There are certain terms which apply to heraldic fish which should be noted. A fish in a horizontal position is termed "naiant," whether it is in or upon water or merely depicted as a charge upon a shield. A fish is termed "hauriant" if it is in a perpendicular position, but though it will usually be represented with the head upwards in default of any specific direction to the contrary, it by no means follows that this is always the case, and it is more correct to state whether the head is upwards or downwards, a practice which it is usually found will be conformed to. When the charges upon a shield are simply blazoned as "fish," no particular care need be taken to represent any particular variety, but on the other hand it is not in such cases usual to add any distinctive signs by which a charge which is merely a fish might become identified as any particular kind of fish. The heraldic representations of the _Dolphin_ are strangely dissimilar from the real creature, and also show amongst themselves a wide variety and latitude. It is early found in heraldry, and no doubt its great importance in that science is derived from its usage by the Dauphins of France. Concerning its use by these Princes there are all sorts of curious legends told, the most usual being that recited by Berry.
