8 THE FEEBLY INHIBITED. 



II. CLASSIFICATION OF NOMADISM. 



Various attempts have been made to classify cases of nomadism. 

 Of these one of the most elaborate is that of Meunier (1908) which is 

 reproduced here in simplified form : 



A. Nomads of economic or social origin. 



I. Legitimate nomads. 



(i) Laborers without work ; (2) exiles; (3) representatives of traveling 

 professions (traveling men, peddlers, explorers, missionaries). 



II. Delinquent nomads. 



Fugitives from justice, recidivists of prisons and asylums, and 

 certain dangerous degenerates. 



B. Nomads of morbid origin. 



I. Physical insufficiency. 



(i) Temporary (e. g., children, adults, sick); (2) definitive (old men 

 and the infirm). 



II. Psychic insufficiency. 



(1) Neurotic; neurasthenic, hysteric, epileptic, "original and eccen- 



tric," degenerate. 



(2) Psychopathic: the excited-depressed, the recurrent, the paranoiic 



and mystic, the intoxicated (alcoholic, pellagric), the demented 

 (precocious, senile, and paralytic). 



C. Nomads of ethnic origin. 



Goths, Saxons, Huns, Normans; Crusaders; Gypsies, Arabs, Sioux, 

 etc. 



Joffrey and Dupouy (1909) use a simpler classification, as follows: 



1. Fugues of childhood. 



2. Vagabondage and fugues in the feeble-minded. 



3. The fugues of the unbalanced (including capricious, sexual. 



dromomanic, paranoiic). 



4. The fugues of the manic-depressive. 



5. The confusional fugues. 



6. Ambulatory automatism of alcoholic or epileptic origin. 



Parent (1909) has suggested a classification of fugues as: (i) melan- 

 cholic; (2) somnambulistic; (3) epileptic; (4) impulsive and demented 

 (of dementia precox) ; (5) dromomanic; (6) of the second state (e. g., 

 hypnotic or of "double personality"); (7) systematized; (8) banal. 



A consideration of these three classifications of forms of nomadism 

 leads to the inquiry : What do they mean ? Are they groups of mental 

 idiosyncrasies each of which is due to a distinct and independent set 

 of causes ; or have they all the same primary cause at bottom, so that 

 the different manisfestations are due to a difference in secondary 

 causes depression, epileptic attack, dementia precox, and the rest? 

 The answer to this question can, I think, be secured only from a study 

 of the family histories ; for these will tell us something of the associated 

 traits and the nature of the stock from which nomadics arise. Such 

 family histories are given in the present paper. We shall study them 

 in detail to get such light as they can give us on the true relationship 

 of the different "forms" of nomadism.
