UEMARKS AND REFERENCES TO LITBRATURB. 



1 (vol. i. p. 2). Anthropogeny (Greek) = History of the Bvoln- 

 fcion of Man; from Anthropos (av^pwTros) = man, and genea (yevea) 

 = Evolution history. There is no especial Greek word for " the 

 history of evolution ; " in its place is used either yeved ( = de- 

 scent), or yoveia (= generation). If goneia is preferred to 

 genea, the word must be written Anthropogeny. The word 

 " Anthropogony,'^ used first by Josephus, means, however, only 

 " the generation of man." Genesis (yei/eo-ts) means " origination, 

 or evolution ; " therefore Anthrojpogenesis = " the evolution of 



man." 



2 (i. 3). Embryo (Greek) = germ {tfjiPpvov). Really to cvtos 

 r^s ya(TTpo'i ppvov (Eust.), i.e. the unborn germ in the mother's 

 body (Latin foetus, or, better, fetus). In accordance with this 

 original sense, the term embryo should only be applied to those 

 young organisms which are still enclosed in the egg- coverings. 

 (Cf. " Generelle Morphologie," vol. ii. p. 20.) Inaccurately, how- 

 ever, various free-moving young forms of low animals (larvae) 

 are often spoken of as embryos. Embryonic life ends at birth. 



3 (i. 5). Embryology (Greek) = Germ-science, from embryon 

 {tfxppvov) = germ, and logos (Aoyos) = science. Even now the 

 whole history of the evolution of the individual is erroneously 

 called "embryology." For corresponding with the term 

 "embryo" (see note 2), by "embryology," or " embryogony," 

 should only be understood " the history of the evolution of ihe
