Rare. A comprehensive economic mineralogy that treats the whole of the African continent. It gives a general description of the mining regions, and resources for copper, diamonds, phosphates, salts, sulphates, nitrates, borates, petroleum, mineral springs, mercury, antimony, bismuth, etc. One section covers the minerals of Africa, broken down by country. A continuation was published as La Geologie et les Richesses Minerales de l'Asie (1911).

Rare. An extensive and authoritative work on ore deposits and econmic mineralogy. All aspects of the subjects are treated including the principles, theories of formation, deposit types, etc. All minerals of any economic value are described together with information on where and how they are recovered. Oddly, although a very competent work, it never received the credit it should have and was largely ignored in its time and afterward.
