Attempt to Subordinate Protista to Cell-Theory 301 



and responsive functions. Possibly skin and inner mass may 

 be organization in its lowest terms, though this is not prob- 

 able. The inner mass is probably never entirely structure- 

 less. Even the bacteria, formerly described as homogeneous 

 in their body substance, are now being shown to have con- 

 siderable structure. 



So our guiding star in the study of living beings whose 

 structure is not known, as for example the ultra-microscopic 

 beings to which hog cholera is supposed to be due, is that 

 they are organisms whose organization may be assumed to 

 consist of at least an outer layer and an inner mass. We 

 may presume, too, that portions of the protoplasm of the 

 inner mass are more or less definitely and permanently dif- 

 ferentiated chemically from the rest, but of this there is 

 less certainty than of the differentiation of the outer layer. 



Our contention that cells are subordinate to organisms 

 everywhere and always, whether in unicellular or multi- 

 cellular beings, we may now regard as established.
