if the latter were free from the andradite. This is in fact 
the composition of the pyroxene-syenites destitute of andra- 
dite, found on Sviatoy Noss. "This rock could very well —— 
be called akerite. 
Very close analogies to the sviatonossites may be found 
among the malignites. Thus was designated by Lawson ?!) a 
series of rocks intrusive in the Coutchiching schists around 
Poohbah Lake in the District of Rainy River in the Province 
of Ontario, Canada. Lawson discriminates three different = 
kinds of the malignite forming parts of one and the same 
intrusive mass, viz. nephelite-pyroxene, malignite, garnet- — 
pyroxene-malignite and amphibole-malignite. It will be 
useful, for. the sake of comparison between the malignites 
and the sviatonossites, to quote the analyses of all kinds 
of malignite. I represents the nephelite-pyroxeneé-malignite, 
analyst F: L. Ransome; II is the garnet-pyroxene-malignite, 
analyst W. C. Blasdale; and III the amphibole-malignite, 
analyst J. W. Sharwood. IV is a nephelite-malignite from
