SYMBIOLOGY THE BIOLOGICAL RELATIONSHIPS OF ORGANISMS 157 



They have become the degenerates and perverts among the body cells. 

 Instead of bearing a beneficient relationship toward the cells which gave 

 them origin, they do all within their power to destroy the cells with which^ 

 they are associated. 



Occasionally the leucocytes, the lymphocytes and the endothelial 

 cells of the capillaries go on a strike, not only refusing to continue the per- 

 formance of their normal functions, but undergoing active disintegration 

 thus bringing about a symptom complex which soon leads to the death of 

 the entire organism, as in purpura hemorrhagica and in pernicious anemia. 

 These]degenerative changes appear to have some intimate interrelationship 

 with the sympathetic nerve system. It would appear that the con- 

 tinuous and prolonged suppression of the emotional feelings and sympa- 

 thies leads to the degenerative cell changes mentioned. No doubt the 

 endocrine secretions are also profoundly altered in these cases. Numer- 

 ous fatalities due to cellular disintegrations have occurred during the World 

 War among those who for various reasons were obliged to completely 

 suppress or hide their true emotional feelings. The peculiar patho- 

 genic cell proliferation encountered in malignant growths are not induced 

 by the suppression of the emotions. Neither the direct nor the inciting 

 causes of these formations are as yet known. 



By heterocytosis is meant a foreign cell proliferation in or upon an 

 organism. Thus cancer tissue may be transplanted upon a mouse. 

 Tissues and organs may be transplanted into widely distinct animals. 

 These interesting cell proliferations are sufficiently common as not tor 

 require further explanation as to their nature. They are unquestionably 

 of symbiotic nature.
