title: [Tonsteins of cinereous origin and pneumoconiosis].
abstract: The incidence of coal-miner's pneumoconiosis in different French coal-fields presents local characteristics for which no satisfactory explanation has been given so far. By studying the total incidence of pneumoconiosis cases in the coalfields it appears that there is a relationship between the distribution of pneumoconiosis and the presence in the coal-seams of tonsteins as formations of cineritic orgin.
