PREFACE 



If one were possessed with the geocentric theory, innumerable 

 astronomical facts ever known would appear to him to be extremely 

 confused. At present an immense number of phenomena concerning 

 living matter have been investigated and almost every detail of them 

 has been fully explored. However, the author felt that they might 

 mostly be not duly understood, so that biology might appear only an 

 enormous accumulation of facts not to be entitled to be called a 

 "science." Where numbers of related facts are fully understood and 

 arranged orderly on system there may emerge a "science." 



Indeed, most of numberless biological phenomena known appear 

 to be extremely complicated and incomprehensible. Such a chaos might 

 have prevailed the brain of the geocentrist. The Copernican theory 

 may be needed in order for biology to become a "science." 



The author felt that he found a theory by which all the life 

 phenomena might be explained most simply and by which every known 

 fact without exception might be arranged on system orderly. The 

 theory was founded on the numerous facts found by the author and 

 his collaborator. Dr. Ohashi, and has been advanced, as he believes, 

 by applying modern researches carried out by other workers especially 

 in virology. 



The manner whereby the theory has developed as well as the way 

 in which numerous biological phenomena are arranged orderly accord- 

 ing to the theory are described in this book. The more fundamental 

 parts of the theory are treated in detail in the sister volume of this 

 book, "Immunity." 



It is very regrettable that the author's concept may not be fully 

 expressed in these two books, because English is not his mother 

 tongue and besides he was unfortunately never blessed with any 

 aptitude for languages.
