This index was not published in Wingate’s “Report on the Dervish Rule in the Eastern Sudan” (May 1891), a fact which now cannot be explained.
It is likely that this index refers to a letter-book kept at Durham (SAD 97/3), but this requires verification, especially since it is currently, labelled as a collection of “majālis” (i.e. texts produced during councils of the Mahdī), and not as a collection of “manshūrāt” (i.e. proclamations set as letters).
