Another way of bringing in the hand along with the fingers is by drawing a dark central patch or knob. This not infrequently occurs without the fingers as the symbol for hand. It becomes a complete symbol by arranging finger-lines after the pattern of a burr about this (see above, p. 347, Fig. 15 [(a)]).
A further process of artistic evolution occurs when the fingers take on contour. This gives a look of branching leaves to the hand. The leaf-like pattern may be varied in different ways, among others by taking on a floral aspect of petal-like fingers about a centre, as in the two annexed drawings by boys of six (Fig. 23 [(a)] and [(b)]; cf. above, p. 350, Fig. 20 [(a)]).

One curious arrangement by which a thickened arm is made to expand into something like a fan-shaped hand appears with considerable frequency. It is zoologically interesting as being a kind of rough representation of the fundamental typical form from which hand, fin, and wing may be supposed to have been evolved. Here the arm sinks into insignificance, the whole limb taking on the aspect of a prolonged hand, save where the artist resorts to the device of making the double organ go across the body (Fig. 24 (a) and (b)).
