The use of the term Phylembryonic does not really clash with 

 Jackson's term Phylembryo ; for the Phylembryo of the individual 

 represents the Phylembryonic stage of the race : the essential morpho- 

 logical features of the two are the same. 



Stages of individual Morphogenesis. 

 Yet another caution as to the use of the above terras seems re- 

 quired. As already pointed out, the various characters that go to the 

 formation of an individual or a race, at any one period of its develop- 

 ment, may themselves differ greatly from one another in the degree of 

 their own development. It is possible to trace the evolution of one 

 character, from its first appearance to its final loss , right through the 

 history of a long line of individuals. For the designation of the suc- 

 cessive stages in the history of a character, the ontogenetic terms 

 might be used, with the addition of the prefix morpho-, e. g. Mor- 

 phobrephic, Morphephebic. 



Auxology. 

 It does not seem to us that any apology is needed for the title of 

 our paper. Growth and change do not stop when the embryonic stage 

 has been passed, nor is the study of later stages of less importance 

 than that of the earlier. It is indeed possible that the application of 

 these principles to some of the problems of Anthropology and Socio- 

 logy might prove of practical utility. To predict the future , as the 

 study of gerontic characters enables one to do, is neither less fascinat- 

 ing nor less valuable than the embryologist's decipherment of the past. 

 And yet, while a part of this science has its special name, its text- 

 books , and its professors , the whole science, through being unchri- 

 stened, is in danger of also being unrecognised. In proposing for it 

 the name »Auxology«, we fulfil a want that may not indeed have long 

 been felt, but that would otherwise have been felt more and more
