good many of the specimens which would well repay careful 
examination. The schist from Bergen is exactly similar to 
one of the Highland series from Loch Tarbert, and would be 
very interesting in section. 
It is worth notice that tourmaline appears to be, if not 
absent, very inconspicuous, so that, in spite of the similarity 
mentioned above between these rocks and some of our pebbles, 
the very widespread occurrence of tourmaline in the latter 
seems to separate them as a whole from the Scandinavian 
series.

glossa stellatarum , Zeuzera QZsculi, and Rterophorus pentadactylus, from

transparent green colour and a port wine colour. Mr. Wallilcer 
exhibited specimens of quartz covered with pyrites, from Lake 
Superior. Mr. W. P. Marshall read a paper on “ Singular Water-worn 
Rocks,” met with in his recent trip to the Orkneys and Slietlands.
