ings or of proceedings that go awry ; the function of a 

 foreman centre is mainly that of immediate supervision,. 

 to execute instructions received from the master centre, 

 to issue instructions in matters of routine without 

 reference to head-quarters, but to inform and take 

 instructions from the master centre as emergency 

 arises. This is a true picture of the relations between 

 the cortex cerebri* and the medulla spinalis,f as far as 

 we know or can conceive them." 1 



We have seen through the whole organism, every cell 

 has at least one nucleus and probably a nucleolus the 

 latter a central object a group of molecules. We have 

 seen that the evidence shows that every simple molecule 

 consists of vesicular matter atoms wrapping over each 

 other to form molecules, that these molecules have the 

 power of changing shape and volume just in propor- 

 tion to the amount of Ether held by them at any 

 instant of time. 2 



Every species of atom has its inherent and eternal 

 properties ; these are the energies of the atom or 

 molecule and produce forces. Every molecule has the 

 combined forces of the atoms of which it is built up. 

 Let us regard the central atom, the commander-in- 

 chief of the molecule. Is there a molecule which is- 

 the commander-in-chief of that wonderful complex 

 army of cells the human being ? 



Xow, the evidence both of structure, physiological 

 effects, and of our own personal inner consciousness, is-
