principally reside, to give off nerves, and perfect them 

 into self-substantial nervous organs. 



2056. In man the brain with its nerves curves round ~ 

 like a crosier, and that more perfectly than in any other 

 animal. The spinal cord therefore in the highest forma- 

 tion of the brain returns again parallel to the direction, 



in which it has ascended. 



2057. In the brain there is of necessity the greatest 

 quantity of nervous mass. The brain is the nervous 

 trunk, as the liver is probably the vascular trunk. 



2058. In the brain the cystic formation has been 

 most purely represented ; as e. g. in the cerebral cavities j 

 or ventricles. The brain is the stomach of the nervous / 

 system or its lungs. / 



2059. The brain consists essentially of two substances, 

 of one accommodated to the flesh, and one to the bones, 

 or of one arteriose, and the other venous. The former is 

 the gray or cortical, the latter the white or medullary sub- 

 stance. The cortex is the lung of the brain, the medulla 

 the liver or the intestine. 



2060. The bark or cortex is the polarizing, active, 

 oxydizing ; the medulla the patient or suffering. 



2061. This nervous pulmonary substance is continued 

 along the spinal cord and even along the nerves, there 

 as veritable gray substance, here as the vascular mem- 

 brane of the nervous mass. 



Head. 



2062. The brain, as being a system that has been 

 separated superiorly from the other systems, determines 

 the Head. The head is only there in so far as a brain is 

 there. 



2063. Head and trunk are antagonistically disposed, 

 as Animal and Vegetable, or still more exactly, like 

 nerve and bony flesh are to the viscera. 



2064. The head is naught but a nervous organ. 



2065. The concomitants of the nervous mass follow the 

 brain, but, instead of the medulla having been previously 

 subordinated to, or at least co-ordinated with, these,
