The term _invected_ reminds us that so far we have only spoken of ordinaries which have straight unbroken outlines. But there are at least thirteen different ways in which the edge of an ordinary may vary from the straight line. Here, however, we can only mention the four best-known varieties, termed, respectively, _engrailed_, (Fig. 33, 1), _invected_ (2), _embattled_ (3), and _indented_ (4). Other varieties are known as _wavy_, _raguly_, _dancetté_, _dovetailed_, _nebuly_, etc. Whenever any of these varieties occur, they must be blazoned before the tincture. Thus in describing the Shelley arms, Fig. 50, we should say: "Sa, fesse indented, whelks or." Fig. 34 shows a bend embattled, Fig. 35 a fesse engrailed. [Illustration: FIG. 33.] [Illustration: FIG. 34.] 4. The next thing to be blazoned is the principal charge on the field. If this does not happen to be one of the chief ordinaries, or if no ordinary occurs in the coat of arms, as in Fig. 38, then that charge should be named which occupies the fesse point, and in this case the position of the charge is never mentioned, because it is understood that it occupies the middle of the field. When there are two or more charges on the same field, but none actually placed on the fesse point, then that charge is blazoned first which is nearest the centre and then those which are more remote. All repetition of words must be avoided in depicting a coat of arms, the same word never being used twice over, either in describing the tincture or in stating a number. [Illustration: FIG. 35.] Thus, in blazoning Lord Scarborough's arms (see coloured plate), we must say: "Arg., fesse gu., between three parrots vert, collared of the second," the _second_ signifying the second colour mentioned in the blazon--viz., gules. Again, if three charges of one kind occur in the same field with three charges of another kind, as in the arms of Courtenay, Archbishop of Canterbury, who had three roundles and three mitres, to avoid repeating the word three, they are blazoned, "Three roundles with as many mitres." When any charge is placed on an ordinary, as in Fig. 41, where three calves are charged upon the bend, if these charges are of the same colour as the field instead of repeating the name of the colour, it must be blazoned as being "of the field." We now come to those charges known as "marks of cadency." They are also called "differences" or "distinctions." [Illustration: FIG. 36.]
