Q. Can you find an article for me: Max Gluckman, "The Role of the Sexes in Wiko Circumcision Ceremonies" in SOCIAL STRUCTURE Essays Presented to A.

Gluckman's article appeared as a chapter in the festschrift published in honor of A.R. Radcliffe-Brown:

Fortes, Meyer, ed., Social Structure: Studies Presented to A.R. Radcliffe-Brown (New York: Russell & Russell, 1963).

Our library does not own the book, and I searched for it via WorldCat and discovered that no library in Nebraska claims to have it.  I could not find any online source for it (e.g. the Internet Archive, Google Books, HathiTrust), so I can only recommend that you submit an Interlibrary Loan request to borrow it from another library.  In the Notes field of the ILL form, I would include WorldCat 2341583.  That is the number for the specific WorldCat record, and it may help speed the request a bit.
