The N'Goureyma meteorite has a recorded fall date of June 15th, 1900 and was said to have fallen near Djenne, Ke Macina, Mali in Africa. It was a remarkably oriented specimen weighing 37.5kg which was reportedly recovered from a hole 1m deep in clay. The single mass was acquired by H. Minod (from Comptoir Minéralogique et Géologique, Geneva), who cut and distributed it from 1900 and in the following years at a price of 2-3 Francs per gram. An old photomicrograph (Cohen, 1901a) is pictured below and details the original amazing shape of this meteorite.

Account on the fall, recovery and analysis of the unique N'Goureyma iron by the grandmaster of iron meteorites Emil Cohen. The author describes the exceptional meteorite as an oriented shield and provides in total three photographic images that were taken on behalf of Minod. Because the chemical analysis of the meteorite had already been completed and preliminary results were published by Meunier, Cohen focusses on the shape and the reconstruction of flight and ablation processes that lead to the particular form of the meteorite.
