Malignite, a New Family of Rocks.— Lawson 2 uses the name 

 malignite for a family of basic orthoclase rocks constituting an intru- 

 sive mass, possibly laccolitic, in the schists around Poohbah Lake, in 

 the Rainy River district, Ontario. Three phases of the intrusive mass 

 are recognized — a nepheline-pyroxene-malignite, a garnet-pyroxene- 

 malignite and an amphibole-malignite. The constituents common to 

 all phases are orthoclase, aegerine-augite and apatite. In the nephe- 

 line variety the nepheline occurs as patches in the orthoclase, or as 

 micropegmatitic intergrowths with it. The orthoclase is in poikilitic 

 relations with all the other minerals, surrounding them like the glass
