THE BEGINNINGS OF LIFE. 



4. Living matter being already in existence, it may 



after a time undergo a thorough molecular re- 

 arrangement whereby it acquires fresh powers 

 and an increased vitality, fitting it for inde- 

 pendent existence. By this process — for which 

 we propose the name Biocsenosis ^ — the spore is 



produced in (Edogonium and other alg^e. 



and 



also, after ^conjugation/ in Valmoglaa and the 



Zygnemeace^ ^. 



5. Lastly, in the midst of already existing living 



matter (in the form of cell or plastide) there 

 may arise a new centre of growth and life, which 

 may subsequently lead an independent existence. 

 Such is the mode of origin of the embryo in all 

 Fhanerogamta^ of the majority of spermatozoa, 

 and possibly of the ova in Birds and Mammals ; 

 also of nuclei in many plastides, which may 

 outlive the latter and subsequently lead an inde- 

 pendent existence. These processes we propose 

 to include under the name Bioparadosis^. 



^ From ^ios, ' life,' and /caivcocris, ' renewal.' 



^ These are some of the phenomena spoken of by Alexander Braim 

 under the name 'Rejuvenescence' (Verjiingung). 



^ From Pios, 'life/ and napadojais, 'transmission.' The phrase ' free 

 cell formation,' as used by older writers, includes these endogenous 

 processes, and also that which we designate Archebiosis, There is, 

 moreover, a certain resemblance between Arcbehiosis and Bioparadosts. 

 In the one case a centre of Life is initiated in the midst of mere 

 organizable matter, whilst in the other it is initiated in an equally 

 mysterious way in the midst of already existing living matter, fne
