NOMENCLATURE OF FELDSPATHIC GRANOLITES lit 
should, it seems to me, have the adjective form, as quartziferous 
syenite for a syenite containing some quartz. If such a scheme 
came into general use the term granite would still be a useful one 
for nearly all quartz-feldspar rocks, in which sense it is used by 
Michel Lévy and by many other geologists.
