PRESIDENTIAL ADDRESS. 



A man of one moiety marries a woman of another, and their 

 children, in a female descent tribe, pass into the mother's moiety, 

 and in a male descent tribe into that of the father. 



,So far as the main features of organization are concerned, the 

 tribes over the whole Continent may be divided into three groups 

 ■ — (1) those with female descent and moieties, which may or may 

 not be* divided into classes; (2) those with male descent and 

 moieties, which are always divided into classes, which again may 

 be divided into sub-classes; and (3) a few highly modified ones 

 occupying a mere fringe of the Continent, mainly in the extreme 

 north and south-east.
