MINERALOGY. 237 



I. Thorite from the felspar-quarries near Arendal in Norway. This 

 mineral, hitherto found only at Brevig in Norway, occurs at the new 

 locality as large brown crystals, with fergusonite and orthite, usually 

 attached to plates of black mica, and surrounded by ochre-tinged 

 orthoclase. Analysis given. — II. Cyrtolite from Ytterby in Sweden. 

 Occurs together with fergusonite, xenotirae, and arrhenite. Analysis 

 given. The composition shows a relationship with the American 

 cyrtolite and the malakone from Bjorkboda, Sweden. E. E.

 Didymohelix ferruginea, with a small proportion of amori)hous ferric 

 oxide. E. W. R.
