All that the tables show is that the 5 stocks and the 17 pairs were like in their 

 index and with ranges of the individual fraternities that in the main were 

 similar. In all respects a "pure" biotypic strain had been isolated in this 

 complex species, showing the " customary fluctuations." What was the nature 

 of the fluctuations?

Three possibilities existed with regard to these ranges in the index: (a) 

 they may be entirely environmental in origin and show simply the plasticity 

 of the material in its response to the conditions of the medium; or (6) the 

 range may be due to " impurities " in the organism, which are present in a more 

 or less loosely combined state, but produce divergence and a range in some of
