EVIDENCE PROVING THE STATEMENT OF THE CASE 123 



Thirdly, if any of the trunk system is injured below 

 this centre near the base of the brain, the individual 

 becomes a living death, that is, the whole body loses 

 sensation, it cannot feel, it has no power of movement, 

 but the brain thinks. 1 



condition of a machine, working by the reflex action of the re- 

 mainder of the cerebro -spinal axis." ..." There is 110 doubt that a 

 molecular change in some part of the cerebral substance is an 

 indispensable antecedent to every phenomenon of consciousness."

 1893, pp. 299, 300.)

' ; There can be no doubt that the cerebral hemispheres are the 

 seat of powers, essential to the production of those phenomena which 

 we term intelligence and will; and there is experimental and other 

 evidence which seems to indicate a connection between particular parts 

 of the surface of the cerebral hemispheres, and particular acts." 

 (Idem, p. 300.) 



" Now it is certain that the will, like life, memory, conscious- 

 ness, and other mental functions, is. so far as human knowledge 

 extends, indissolubly connected with matter and natural laws, in the 

 form of certain motions of the cells which form the grey substance of 

 the nerves and of the nervous ganglia of which the cortex of the brain 

 is the most considerable. This is conclusively proved by experiment. 

 We know that, by removing certain portions of the brain of a dog or 

 of a pigeon, we can destroy the power of motion while preserving the 

 will, and by removing certain other portions we can destroy the will 

 while preserving the powers of motion. Take away a certain portion 

 of the brain of a pigeon, and although it retains the power of taking 

 food, it has so totally lost the will to exercise this power that it will 

 starve in the midst of abundance, though it can be kept alive by 

 placing the food in its mouth. In like manner, in the human brain 

 there are certain portions which, if destroyed by injury or disease, 

 will paralyse the power of giving effect to the will by muscular 

 movements, while the destruction of other portions will paralyse 

 the will which originates such movements." ("A Modern Zoroas- 

 trian," S. Laing, 1895, p. 191.)
