62 STUDIES ON THE CENTRAL NERVOUS SYSTEM 



In this third lecture I have tried to give you some im- 

 pression regarding the significance of phylogenetic studies 

 for the neurologist. I have done this by giving examples 

 from normal anatomy, pathological-anatomy and from the 

 clinic. It is clear that this line of thought is more valuable 

 for neurologists than for other clinicians. If there is one 

 part of the body of vertebrate animals, where the great 

 line, going upwards in the direction of man, may be seen, 

 it is in the nervous system. Still I believe that such 

 thoughts are valuable as well for other clinicians and patho- 

 logists. It is possible that such statements may also 

 satisfy the student of other organs of the body, provided 

 he has passed through comparative anatomy. 



My opinion is that in the end the difference in vulner- 

 abihty is caused by a difference in the chemical and physical 

 structure. I cannot believe that ceils and fibres, which have 

 been present and functioned so long before others have, can 

 be chemically and physically the same. But at the present 

 stage of science we do not know very much about the finer 

 and the inner organization of these cells and fibres. Kence 

 we must now resort to such propositions as given above.
