individual within the egg- coverings." As soon as the organism 

 has left there, it is no longer a real " embryo." The later changes 

 of this form the subject of the science of Metamorphoses, or 

 Met a morpli logy. 



4 (i. 5). Ontogeny (Greek) = "germ-history," or "the 

 history of the evolution of the individual;" from 6vra = indi- 

 viduals, and genea (yei/ea) = history of evolution. (Cf. note 1.) 

 Ontogeny, as the "history of the evolution of the individual," 

 embraces both Embryology and Metamorphology (note 3). — 

 " Generelle Morphologie," vol. ii. p. 30. 



5 (i. 5). Phylogeny (Greek) = tribal history, or " the pa- 

 laeontological history of evolution ; " from phylon (<£uAoi/) = tribe, 

 and genea (yei/ea) = history of evolution. The phylon includes 

 all organisms connected by blood, which are descended from a 

 common typical parent-form. Phylogeny includes Palaeontology 

 and Genealogy. — " Generelle Morphologie," vol. ii. p. 305. 



6 (i. 6). Biogeny (Greek) = the history of the evolution of 

 organisms or of living natural bodies in the widest sense. 

 (Genea tu biu.) /3ios = life. 



7 (i. 6). The fundamental law of Biogeny. Cf. my "General 

 History of the Evolution of Organisms" (" Generelle Morphologie," 

 18G6, vol. ii.), p. 300 (Essays on the causal connection of biogenetic 

 and phyletic evolution) ; also the " Monograph of Chalk 

 Sponges " (" Monographic der Kalkschwamme," 1872, vol. i. 471); 

 also my " Natural History of Creation." 



8 (i. 10). Palingenesis (Greek) = original evolution, from 

 palingenesia (7raA.il/ye1/eo-ta) = new-birth, renewal of the former 

 course of evolution. Therefore, Palingeny = inherited history 

 (from TraAtv = reproduced, and yei/ea = history of evolution). 



9 (i. 10). Kenogenesis (Greek) = modified evolution, from 

 kenos (/cevo's) = strange, meaningless; and genea (yei/ea) = history 

 of evolution. The modifications introduced into Palingenesis 

 by Kenogenesis are vitiations, strange, meaningless additions to 

 the original, true course of evolution. Kenogeny = vitiated 

 history.
