lack of physiological balance due to abnormal, i.e., anti-biotic, 

 propensities with the subsequent advent of impurities. 

 " Others in virtue plac'd felicity." 



Pathology constantly illustrates Physiology, and just as I 

 hold that parasitism and anti-biotic habits generally make for 

 loss of proportion and asymmetry, so I consider symmetry 

 primarily as the expression of a well-balanced moving 

 equilibrium well-balanced, that is domestically and bio- 

 logically. We have seen the intimate connection between 

 chemical and bio-economic (symbiotic) factors, and thus it is 

 not a far cry to their connection with mathematical and 

 geometrical phenomena. 



Symmetry and proportion depend on wholesome and 

 harmonious distribution of materials in a living system, and 

 this, in turn, on a series of steady, wholesome and reliable 

 efforts, producing the right kind of external stimulation and 

 of circulation. As all this involves, as we have seen, proper 

 bio-economic activity proper give and take, proper domestic 

 and biological symbiosis, proper restraint, proper sympathy 

 we may also say that symmetry and proportion are a matter of 

 harmonious adjustment to the biological environment. 



We have seen that circulation and, according to Dr. A. 

 Haig, "Life is Circulation" and " full-bloodedness " 

 depend on biological symbiosis, nay more, that animal flesh is 

 for its very existence dependent on perpetual work, i.e., 

 primarily on the photosynthetic work of the green plant as the 

 first beat of a rhythm, and, further, that the progress of all 

 flesh depends in turn on the animal's own bio-economic service- 

 ableness, the secondary (harmonious) beat or return of the 

 rhythm. To be symmetrical and well-proportioned is thus to 

 be in tune with the (biological) world, i.e., with the universe, 

 and the path to that goal is work. 



In his volume on Organic Evolution, Prof. Eimer attempts 

 to explain the famous statue of Apollo Sauroktonos by means 

 of a lizard-catching "industry" widely spread in Italy. The 

 beautiful and symmetrical figure, he thinks, is that of a boy
