Pairs of wings not conjoined can be met with in the arms and crest of Burne-Jones ["Azure, on a bend sinister argent between seven mullets, four in chief and three in base or, three pairs of wings addorsed purpure, charged with a mullet or. Crest: in front of fire proper two wings elevated and addorsed purpure, charged with a mullet or"]; but two wings, unless conjoined or addorsed, will not usually be described as a pair. Occasionally, however, a pair of wings will be found in saltire, but such a disposition is most unusual. Single wings, unless specified to be the contrary, are presumed to be dexter wings. Care needs to be exercised in some crests to observe the difference between (_a_) a bird's head between two wings, (_b_) a bird's head winged (a form not often met with, but in which rather more of the neck is shown, and the wings are conjoined thereto), and (_c_) a bird's head between two wings addorsed. The latter form, which of course is really {240} no more than a representation of a crest between two wings turned to be represented upon a profile helmet, is one of the painful results of our absurd position rules for the helmet. A pair of wings conjoined is sometimes termed a vol, and one wing a demi-vol. Though doubtless it is desirable to know these terms, they are but seldom found in use, and are really entirely French. [Illustration: FIG. 459.--An eagle's leg erased à la quise.] Eagles' legs are by no means an infrequent charge. They will usually be found erased at the thigh, for which there is a recognised term "erased à la quise" (Fig. 459), which, however, is by no means a compulsory one. An eagle's leg so erased was a badge of the house of Stanley. The eagle's leg will sometimes be met with couped below the feathers, but would then be more properly described as a claw. [Illustration: FIG. 460.--Phoenix.] A curious form of the eagle is found in the _alerion_, which is represented without beak or legs. It is difficult to conjecture what may have been the origin of the bird in this debased form, unless its first beginnings may be taken as a result of the unthinking perpetuation of some crudely drawn example. Its best-known appearance is, of course, in the arms of Loraine; and as Planché has pointed out, this is as perfect an example of a canting anagram as can be met with in armory.
