244 THE BIOCOSMOS PARTICULARIZED. 



neutrals Protista (an insufficient rubric by 

 the way, since it applies to non-vital things 

 as well). Moreover it is sometimes called 

 the third -kingdom of Life out of which the 

 other two fork. Now this pivotal parting of 

 the ways is what we are next to see, if it be 

 possible. In other words the double-natured 

 Pliytozoa are to split into their two elemental 

 constituents, which are named the Protophyta 

 and the Protozoa, or the first Plants and the 

 first Animals. The latter line of Life-forms 

 we shall pick up hereafter, when we come to 

 the animal world. Here, however, we may 

 add that the two samples of earliest bifurca- 

 tion are usually considered to be the Bac- 

 terion as first plant and the Amoeba as first 

 animal, both of them moving almost on par- 

 allel lines of evolution. Thus Biology takes 

 its double start in many a text-book and re- 

 mains double to the end. 



But having gotten our first Plant and with 

 it the first faint indication of the Plant-norm 

 (Protophyte), how shall we organize the 

 overwhelming multiplicity of the Plant- 

 world? Perhaps the best start in running an 

 organic line is to divide (after De Condolle) 

 the entire mass of vegetation into the non- 

 vascular and the vascular (without and with 

 circulatory organs for carrying fluids) even 

 if we have later to change partly this divis-
