while a Jens shows black hornblende in addition. orm Te ists 
and mica-schists are found also of various types, one not uncommon 
like the grain of wood around knots. A finer-grained type has 
smaller garnets, and the white mica more prominent relatively to 
the dark. 
Other types met with among the Holderness boulders might be 
referred to, but with less certainty as to the precise locality of their 
home; such, for instance, as certain quartzites possibly from the 
quartzite-conglomerates of the Bergen district ; and no doubt many 
of the remarkable metamorphic rocks there studied by Reusch may 
have furnished specimens to the ice-sheet which reached our shores. 
Further examination would be certain also to detect more types 
from the Christiania district; probably the red quartz-syenite which 
Brogger has named ‘ nordmarkite,’ which covers a considerable area 
of ground, and his ‘laurdalite,’ a rock allied to the augite-syenites 
noticed above, but containing, in addition, the minerals elzolite and 
sodalite. Indeed an English mineralogist might, perhaps, profitably 
— among our boulders for examples of the ‘syenite-pegmatite- 
veins’ in which the geologist just named has found so long a list of 
rare and remarkable minerals. I have said enough, however, to 
show that these strangers among our local boulders, although they 
form but a small percentage of all those embedded in the clays and 
washed out on to the modern beach, may usefully occupy a collector 
in the district and afford material for interesting petrological studies, 
while illustrating one of those links between Yorkshire an 
Scandinavia of which another writer has spoken in a recent volume 
of ‘ The Naturalist.’ OR eR Ecos
