1. A typical uncomplicated case of silicosis with fatal outcome in a porcelain turner is described.
2. Microscopic examination of lung tissue and of ashes therefrom showed numerous mineral needles resembling those found in kaolin from his factory.
3. The findings in this case are taken to support in part the theory advanced by W. R. Jones, that silicosis can be produced by fibrous minerals.
We are indebted to Mr Bögvad, M.S., for valuable aid in the mineralogical diagnosis.
