... I FELL INTO A REVERIE ... THE ATOMS WERE GAMBOLING BEFORE MY EYES ... I SAW HOW TWO SMALL ONES UNITED TO FORM A PAIR; HOW THE LARGER ONES SEIZED TWO OF THE SMALLER ONES; HOW STILL LARGER ONES KEPT HOLD OF THREE OR FOUR SMALLER ONES ... I SAW HOW THE LARGER ONES FORMED A CHAIN ... THIS WAS THE ORIGIN OF THE STRUCTURE THEORY. -- C.F.KEKULE VON STRADONITZ
