Roundels in colour, which should be shown as hemispherical. They doubtless represent the bosses on a shield. The metal roundels, however, the Bezant of gold, and the Plate of silver, no doubt represent coins, and are shown flat; and that Cadency marks may correctly be represented, as in relief on a shield. Heraldic charges are numerous, and if any prolonged investigation is likely to be required their names and forms will have to be learnt. But a few of the commoner charges may well be explained here, as such explanation may possibly in many cases save a long search. [Illustration: A <i>Dragon</i> is a monster with scales all over him; he has four legs ending in eagle's talons and a spear-head at the end of his tail, his wings are like the wings of a bat, with a claw at the end of each rib.] [Illustration: A <i>Griffin</i> has the head, front legs, and wings of an eagle, and the hind-quarters of a lion.] [Illustration: A <i>Wyvern</i> has a dragon's head and wings, with two eagle's legs, his tail is curled round itself and ends in a spear-point. He is scaly all over.] A _Cockatrice_ is a Wyvern with a cock's head. A _Basilisk_ is a cockatrice with its tail ending in a dragon's head. A _Lion_ shows one eye, one ear, and stands upon one foot, rampant. He has a mane, and his tail has a tuft at the end, and he shows no spots. If a lion is otherwise depicted it must be mentioned in the blazon. A lion showing two eyes and two ears is a lion "Leopardé." A _Leopard_ shows two eyes and two ears; he has no mane and his tail is not tufted. He should show spots and be "nowhere shaggy." If he only shows one eye and one ear he is a leopard "Lionné." Most of the other animals explain themselves, but there are a few curious charges, no doubt survivals of common forms, which also retain their ancient heraldic names, and these forms and names are useful to remember; among them the following occur perhaps most frequently:-- [Illustration: A Caltrap.] [Illustration: A Chess-rook.] [Illustration: A Clarion.] [Illustration: A Fer-de-Moline.] [Illustration: A Fermail.] [Illustration: A Fountain.] [Illustration: A Fret.] [Illustration: A Fusil.] [Illustration: A Mascle.] [Illustration: A Maunch or Sleeve.] [Illustration: A Pheon.] [Illustration: A Rustre.] [Illustration: A Water Bouget.]
