FORMATION OF LIVING ORGANIZED BODIES. 3 



reason the micellae remain so small that they are 

 invisible, even with the microscope. 



On account of their great affinity for water the 

 micellae surround themselves with a thick film 

 of it. The attraction of these micellae for matter of 

 their own kind is felt outside this film. Hence the 

 micellae with their films unite themselves into solid 

 masses permeated with water, unless other forces 

 overcome attraction and re-establish a micellar 

 solution (as in albumen, glue, gum), where the 

 slightly moving micellae show a tendency to cling 

 together in chain-like and other aggregations. Very 

 often there are found, especially in albumen, half 

 liquid modifications intermediate in fluidity between 

 the solid masses and the micellar solution. 



The internal and external constitution of micellar 

 bodies depends essentially on the size, form and 

 dynamic nature of their micellae, since these effi- 

 cients condition the original arrangement of the 

 micellae and the insertion in proper order of those 

 formed later. External conditions have slight influ- 

 ence on structure, and affect outer form chiefly in 

 so far as they can mechanically hinder free develop- 

 ment. 



The micellae of albumen or plasma are susceptible 

 of the greatest diversity of form, size and chemical 

 composition, since they originate from unlike mix- 

 tures of various albumen compounds, and besides 

 are mixed with various organic and inorganic sub-
