 esis, and a stationary factor in evolution. 



The above table is designed to be a classification 

 and formulation of the innumerable well-known facts 

 of organic growth and evolution. It does not pre- 

 tend to be an explanation of the processes involved, 

 but it is the first step to be taken in attempting the 

 explanation, i. e. a discrimination and classification of 

 its factors. 



Ryder thus expressed the relation between stato- 

 genesis and kinetogenesis.^ 



"So universal is this interference of the statical 

 conditions of the plasma of segmenting ova with the 

 ontogenetic processes, that not a single metazoan or- 

 ganism can be named, the development of which is not 

 thus marred in some way or other. It is often a long 

 time relatively after development has begun that there 

 is any obvious delineation of the embryo. In fact, 

 this cannot take place until the statical energies of 

 surface-tension which have kept the egg globular are 

 overridden. In so far as the ontogeny of any organ- 

 ism is marred by statical conditions of energy- display, 

 its embryonic form is also modified. In so far as such 

 statical interference affects the figure of the organism 

 they are morphogenetic or form-determining. In so 

 far the figure of a developing being is disturbed or
