MIND AND BRAIN. 2OI 



in two rows in front of the spinal column (s, Fig. i). 

 Each of these small centres is named a gang/urn, which is 

 the Greek word for a swelling. This name has been 

 given them because they make swellings on nerves like 

 knots on a string. These ganglia are joined to one an- 

 other and to the brain and spinal cord by nerves. They, 

 with the nerves running to and from them, look after a 

 good many of the details of the working of the body. 

 The sympathetic system is a sort of tinder-servant of the 

 brain and spinal cord, trusted to look after certain routine 

 work, especially the distribution of the blood among the 

 various organs, according as their needs may be. It has 

 also much to do with managing the glands. It owes 

 its name to the fact that it makes many organs which 

 are not under direct control from the will, work together 

 as if they sympathized with one another. 



12. Mind and Brain. The cerebrum is not only con- 

 cerned in feeling and willing, but in remembering and 

 reasoning, and in all the other things which go to make 

 up what we call mind and character. How mind is con- 

 nected with brain it is not possible to imagine ; we have 

 just to accept the fact that it is, and especially with its fur- 

 rowed and ridged surface. When this is seriously dis- 

 eased, feeling is lost or unnatural, the will is enfeebled, 

 memory weakened, reason impaired, and the man no 

 longer capable of judging correctly, nor really responsible 

 for his actions. Why, or how, we do not know, and 



12. With what besides feeling and willing is the cerebrum con- 

 cerned ? What is said of the connection of cerebrum and mind ? 

 What part of the cerebrum has especially to do with mind? What is 

 seen when it is seriously diseased ? What is it sufficient to know 

 concerning the connection of brain and mind, for all practical pur- 

 poses ?
