by pyroxenite. Sometimes granite and gabbro are traversed by 
pegmatite veins, and these in turn by veins of graphite. The vein- 
minerals with apatite are pyroxene, mica, calcite, and felspar, also 
actinolite, tourmaline, scapolite, titanite, pyrite, fluorspar, quartz, 
garnet, epidote, idocrase, zircon, prehnite, cabazite, molybdenite, 
graphite, &c. A careful exposition is given of the vein-materials, 
various rocks more or less associated with the apatite-veins, especially 
certain crystalline schists, and some of the eruptive rocks. 
The gneisses, quartzites, vein-granites, and other associated rocks 
have been impregnated from the veins, hence secondary develop- 
ments of some minerals, as augite &e. 
The Kozoon Limestone of Cote St. Pierre is described in full detail, 
as occurring just above the contact of the limestone with the mica- 
hypersthene gabbro, forming the mass of the hill below, and is 
regarded as having resulted from contact-metamorphism. It is com- 
pared with a rock having a similar structure ejected from Vesuvius, 
and described by Johnston-Lavis and Gregory. The presence of 
apatite in the “ Leopard-rock” of Ottawa is referred to, and the mode 
of formation of that peculiar augite-gneiss is explained. 
Graphite is referred to as being widespread, and is described from 
two localities—Graphite City in Buckingham Township and in 
Grenville Township. It occurs mostly in veins, but sometimes 
diffused from them into the neighbouring rocks of gneiss &e. Like 
apatite it occurs with hypersthene-biotite gabbro together with 
scapolite, oxide of tin, hornblende, titanite, and zircon. The 
graphite distributed in the granular limestone of Canada may well 
have been derived from the carbon originally in the limestone, and 
possibly of organic origin, but subsequently modified by the 
metamorphism which changed the limestone into marble. 
It is highly probable, however, that fumarole-action had to do 
with the formation of both the apatite and graphite veins, filling up 
cracks and fissures, in the old cooling rock-masses, during their 
solidification,
