344 SYMBIOGENESIS 



abundant nutrition continued through several thousands of 

 years does not produce constant characters in a species of plant, 

 so that the species could no longer exist if brought again under 

 conditions more unfavourable (?) to nutrition." 



My contention, once again, is that specially abundant 

 nutrition over long periods of time does precisely produce 

 pathogenetic, precarious and often fatal results, both in 

 animals and in plants, though, it is true, quite definite and in 

 a sense orthogenetic. Such results frequently, as we have seen, 

 make desirable reconversions impossible, and they tend, in 

 Prof. Eimer's own words, to burden the organism with harmful 

 characters. 



It is precisely a faulty or abundant nutrition that leads to 

 a faulty distribution of blood, and hence to physiological 

 pauperisation and misere. 



It is also true, as mooted by the same zoologist, that the 

 time element requires due consideration. Once this element is 

 truly focussed, the value of symbiogenesis is apt to become 

 specially apparent. It is not to be denied that both in-feeding 

 and over-feeding are quite possible for a time. But such modes 

 of feeding are unsound and fallacious from the more 

 permanent racial, biological and cosmic points of view. I 

 have provided plentiful biological and sociological instances 

 in proof thereof in my previous writings, and I feel I cannot 

 insist enough on these important connections. 



Prof. Eimer points out quite correctly: "Only by 

 gradually bringing the organism slowly, step by step, during 

 a very long period of time into new conditions if, moreover, 

 the new conditions harmonised with the direction given to the 

 evolution could the artificially-produced characters possibly 

 be maintained." 



But what about the "direction given to the evolution "? 

 It requires, I maintain, the recognition of values and the 

 possession of a valid biological analysis to discern on what 

 path of evolution a species is travelling. We have seen it 

 confirmed in the case of anaphylaxis, which is hereditary and
