The recordings were made in December, 1974, and January, 1975, in the course of field work by Research Group 165 of the Centre National de la Recherche Scientifique. This work was realized at the instigation of Dan Sperber (Laboratoire Associé 140 of the C.N.R.S.) and in large part with his collaboration.
The constant cooperation of his assistants Girma Kodo and Wondimo Tekola has been an invaluable help in these researches. May they be here sincerely thanked.
