serious. Usually hallucinations are visual, and thus stones look 

 like buildings or large rocks, while caravans or files of soldiers may 

 be seen which do not exist. It has nothing to do with true mirage. 



Chalmers has met with a case which occurred in the Egyptian 

 deserts, in which the attack at first only came on during the night, 

 but once occurred in the day. Its causation appeared to be due to 

 very hard work and mental worry. The symptoms quickly dis- 

 appear under the influence of rest, better food, and cessation of worry. 



EMOTIONAL EXCITEMENT. , 

 Synonym. — Misala. 



Howard, in a very interesting paper, has recorded cases of 

 emotional excitement called ' misala,' which vary from an attack of 

 tropical anger to a condition almost bordering on mania, which can 

 be controlled by authoritative commands, or which, left to them- 

 selves, pass off in a few hours or days. It occurs among the young 

 adult males of Nyassaland. 



DELUSIONS. 



Delusions of poisoning and of bewitchment are common in Africa 

 and Asia, and probably elsewhere, and are common explanations 

 of various forms of disease or of hysteria. 



AUTO-SUGGESTION. 



Every practitioner in Africa and Asia is acquainted with the 

 extraordinary ease with which a native can die if he makes up his 

 mind to do so. The actual cause of death is often exhaustion due 

 to starvation. It should be treated by suggestion.
