68 THE HUMAN BRAIN. 



the body into the terminal loops, from whose fingers' ends it flies 

 with its ministering spirits, and is again received into the blood, 

 whose life it constitutes, and which it incites and forces to construct 

 the body on the principles of the wisdom of the soul and brain. 

 Thus the nervous circulation has solid channels only in the highest 

 or proper sphere ; in the rest it runs through the fluid blood. More- 

 over this system has its excretions just like the vascular; in the 

 ventricles of the brain ; in every interstice of the nerves : so that 

 when it comes into its loops, it has put off the body it assumed, and 

 is again received into the red circulation. Thus the aged spirit of 

 the nerves becomes the youngest life of the blood. This is neces- 

 sary to the continuity of existence : for every end is a new begin- 

 ning in the vortex of our providential universe. We now then see 

 that without this openness of the brain, this animal spirit, this mo- 

 tion of the brain, and this nervous circulation, the soul could not- be 

 incarnate, nor the body animate; nor could the latter for a moment 

 preserve that unanimity which gives it coherence, and constitutes it 

 the ideal not only of physical, but of all social unity. 



If, however, there be other principles of explaining these things, 

 then we ardently desire to know them. But explanation must be 

 attempted, for the people is weary of hearing that they cannot be 

 investigated; and from men, too, whose powers have no preeminence 

 to entitle them to set limits to the faculties of any new child who 

 may be born into the world. We know of but One whose rights 

 went to this extent, but His voice was, " Seek, and ye shall find; 

 knock, and it shall be opened unto you." 



It will not be difficult now, on these principles of motion, to dis- 

 cuss the problem of the respective uses of the cerebrum and cerebel- 

 lum. And in order to approach the subject we would make the 

 following remarks. The nervous system is a casket of stimuli of 

 various orders superadded to the body : the bodily parts or animals 

 are constructed mechanically without it, and only wait to be ordered 

 into action by its spirits or voices. These spirits give different in- 

 structions according to the chamber whence they issue. The voice 

 of the spinal brain to the body produces mimetic perceptions and 

 motions; states that seem to be alive, for they act life perfectly. 

 The spinal cord then endows the body up to the point of represent-
