My dear Sir Your letter of 13 inst has much gratified me and as you are so good as to undertake further enquiries and as you expect the blacks to return soon I write at once to explain my diagram more fully.
I have found this to be the case in a tribe in Queensland which has [thre-crossed out] four subclasses + the same [??] as the Kamilaroi. The question must also arise incidentally which the brother murri of (2) [(Murri) - crossed out]might may the [??] here called (7) Butha and or whether they, being the children of a brother on one side + a sister in the other would be -as among the Dieri forbidden to each other.
[I found this to be the case - crossed out] In similar tribes, [while in another often - crossed out] such as the Ngarabana at Lake Eyre it is these very ones who marry - that is taking the Dieri diagram as thus illustrated it is the brother of (2) who marries (7) - and the brother of (7) who marries (2). The Dieri + the Ngarabana are on opposite sides of Lake Eyre.
The Ngarabana, Dieri, + (theoretically) Wiradjuri marriage rules - form a clear sequence of developments. What I want [to show- crossed out] [now is] now is to verify the theoretical features of the Wiradjuri. If you can do this for me you will help to complete my chapter on "marriage" I have found a diagram of the actual relatives of a man + his wife to show me the facts of [??] are.
[The Dieri - crossed out] In the Dieri's Diagram [The man (1) and the - crossed out] (4) and (6) and (3) and (5) [are] may be either own or tribal brother and sister, and in this tribe there is a reciprocal "betrothal" - for instance 4 + 6 and 3 and 5 were betrothed by their mothers when infants. Their children the girl (2) + her brother (not shown on diagram) and (7) and her brotherl as [in the relation of- crossed out] "Karni mara" - which may be translated as "not marrigable" But their children are "noa-mara" that is marrigable - therefore (1) may marry (8) (being betrothed to each other probably as children) - and their respective brothers + sisters (own and tribal) are in the same conditions.
Suppose now that I were questioning [(1) - crossed out] the man Kubbi (1) in the Wiradjuri diagram. I should write down the name of his mother, who would be Matha (2) then of he mother Kubbitha (3) - then of Ipai (4) the mother of (3). These I should want to know whether (5) was in fact the own or tribal brother of (3) - and (6) the own or tribal sister of (4)
Thus taking their daughter (7) Butha I should want to know whether [the girl - crossed out] [woman - crossed out] her daughter the woman Ipatha (8) - was - or would be properly the wife of my informant Kubbi (1).
