Scientific theories generally have a long and difficult road to travel before gaining acceptance. It is, therefore, somewhat surprising to find that Thiele's theory of partial valency gained such ready recognition. This was undoubtedly due to the fact, as the saying goes, that it filled a long felt want. As time went on and chemists learned more about valence there arose a tendency to question the existence of such a thing as a "partial" valence. But as no alternative explanation was forthcoming to explain the phenomena that Thiele's theory explained so well, no great inroads were made against his hypothesis.
