mother's mother's sisters daujihter's daughter's daughter's 

 daughter — the system appears to be comphcated in the extreme ; 

 it is nevertheless cpiite simple, and easy to be understood. 

 The key to it is shown in the following diagram : —

Group A. 



Group B. 



The diagram shows three brothers and their three sisters, 

 with a son and a daughter to each of them. 



According to our own system Nos, 21, 22, 23, 24, are first 

 cousins to Nos. 19 and 20, and marriage between them is not 

 prohibited ; but the classificatory system makes all these 

 numbers brothej's and sisters, and no connubium between 

 them is permitted. No distinction whatever is made between 

 own brothers and sisters and what we have called, for the sake 

 of convenience, Z?*i&«/ brothers and sisters. INos. 19 and 20 

 are own brother and sister, but they are tribal brother and 

 sister to Nos. 21, 22, 23, 24. 



So also, according to our system, Nos. 13, 14, 15, and 16 

 are first cousins to Nos. 17 and 18; but the classificatory 

 .system makes them all brothers and sisters. 



According to our system Nos. 21, 22, 23, and 24 call No. 

 4 my uncle, and No. 10 my aunt; but according to the 

 classificatory system they call No. 4 my father, and No. 10 

 my mother. 



So also No. 13, 14, 15, and 16 call No. 3 my mother, and 

 No. 9 my father. 



Here then we have two distinct groups, marked on the 

 diagram Group A and Group B, each of which is composed 

 of "tribal brothers and sisters," the individuals being not all 

 of them brothers and sisters according to our own system. 

 If the diagram be continued to the next generation, it will 

 be seen that these groups enlarge, but their construction 

 remains the same to the remotest generation. 



Taking now the other relationships, we find that Nos. 13, 

 14, 15, 16, 17, and 18 address Nos. 4, 5, and 6 by a term 

 which, in Mr. Morgan's tables, is rendered uncle, and Nos. 

 10, 11, 12 by a term which is rendered aunt; but these terms 

 really mean father-in-law and mother-in-law respectively,
