Bipartite structure

[Koontz John E]

I believe the reference on Catawba cognates of Siouan instrumentals that
I've been trying to recall (the article contains various other things,
too) is:

Siebert, F. T. (1945). Linguistic classification of Catawba: I. IJAL 11:
100-4.

Siebert, F. T. (1945). Linguistic classification of Catawba: II. IJAL 11:
211-8.

I obtained the citations from John Boyle's enormously helpful on-Web
Siouan bibliography at
http://puffin.creighton.edu/lakota/siouan_language.html, but the
recollections of their content are my own responsibility.
