Counter-vair and Counter-potent have pieces of the same colour opposed to each other, as in the example of counter-vair (Fig. 41), and it will be noticed that these variations of the simpler furs are inferior to them in that they lose the completeness of the counter-change. In both vair and potent the colour pieces are more frequently than not placed point upwards in relation to the metal ones, but there is no definite rule about this. An ancient form of vair which somewhat resembles potent is Fig. 42. [Illustration: FIG. 43.] [Illustration: FIG. 44.] [Illustration: FIG. 45.] [Illustration: FIG. 46.] [Illustration: FIG. 47.] [Illustration: FIG. 48.] [Illustration: FIG. 49.] [Illustration: FIG. 50.] Having described the tinctures it will now be convenient to return to divisions of the field, the simplest possible variation from a plain shield. A surface is _party per pale_ (Fig. 43) when it is divided by a perpendicular line into two halves, _party per fess_ (Fig. 44) when the line which equally divides the shield is a horizontal one, _party per bend_ (Fig. 45) when it goes diagonally downwards from dexter to sinister, and _party per bend-sinister_ when the diagonal is reversed. The word _party_, however, has now fallen into disuse, and the terms _per fess_, _per pale_ and so forth are considered sufficient. _Per chevron_, _per saltire_ and _quarterly_ are as represented (Figs. 46, 47, 48). _Gyronny_ (Fig. 49) is a combination of the two last named, and the number of its pieces being normally eight, any variation from that number must be expressly mentioned. _Barry_ (Fig. 50) is composed of repeated horizontal lines, which are odd in number, so that the spaces begin and end with different tinctures. _Paly_ (Fig. 51) and _Bendy_ (Fig. 52) are similarly composed of perpendicular and oblique lines respectively. _Chequey_ (Fig. 53) is, of course, made into squares by perpendicular and horizontal lines, and _Lozengy_ (Fig. 54) similarly results from crossing oblique ones. Varieties of the latter form arise from a combination of perpendicular with oblique lines, called _paly bendy_, and of horizontal with oblique, which is called _barry bendy_. Both are of rare occurrence and perhaps resulted from bad drawing of lozengy. [Illustration: FIG. 51.] [Illustration: FIG. 52.] [Illustration: FIG. 53.] [Illustration: FIG. 54.]
