ANIMAL LIFE FORMATION. 289 



ward which all living shapes are advancing 

 and which is their explanation. These parts 

 cannot be called symmetrical, not any two of 

 them, but rather the contrary; their relation- 

 ship is far more internal than external. It 

 should be added that their order is signifi- 

 cant ; though the head is on top, it is not first 

 in an evolutionary or psychical succession ; the 

 Animal starts with a trunk in the cell, or for 

 example, in the Amoeba; the head proper 

 comes last. So we think of this triune se- 

 quence of the divisions of the animal Form 

 as Trunk, Extremities and Head. In the 

 present sphere the main correspondence be- 

 tween the Plant and Animal lies between the 

 Trunk of the one and the Stem of the other; 

 both are in the middle, both are one and un- 

 divided in form, both show a cylindrical ten- 

 dency, both separate into limbs downward 

 and upward, out of both evolve the other two 

 parts. The Trunk of the Animal and the 

 Stern of the Plant were originally one and 

 probably un differentiated in the primal ele- 

 mental Life-stuff (Protobioticon), in which 

 their germinal separation must have taken 

 place into Protozoa and Protophyta (for 

 example, into the Amceba, the unicellular ani- 

 mal and the Bacterion, the unicellular plant, 

 though biologists still differ about these char- 

 acteristics.) Here we again remind the reader
