Figure 1.5 Behaviour of active fields
(1) If a field is cut in half, each portion will develop into a complete unit; they may each retain their original polarity (above) or one may be the mirror image of the other (below).
(2) If two fields are brought together and allowed to fuse, they form a single field (most easily if their polarity is the same).
(3) Ifa central (a) or peripheral (b) region is removed from a field, the remainder will still form a complete unit (above), while the small isolates may each also form complete fields (below).
