babiroussa is a
species of wild hog, peculiar to the islands of Eastern Asia, and
remarkable, in the male animal, for the extraordinary growth and
direction of the canine teeth. The upper pair of canine teeth, growing
out through the upper jaw, curve backward and upward on the forehead,
having somewhat the aspect of horns; while the lower canine teeth form a
pair of crooked tusks in the under jaw. These teeth may be useful for
defensive fighting, as a guard to the head, but could not serve for
attack. The skull of a babiroussa, with the teeth fully developed, is in
the possession of Mr. Bartlett, the able superintendent of the
Zoological Society's collection.--_Illustrated London News_.

Montville, Morris County, New Jersey.--This locality is an old one, and
well known to mineralogists. It is outside of the limits prescribed in
introducing this series of paper, but by only a few miles, and being
such an interesting locality, I have included it in the granular
limestone, which occurs in a small isolated ridge in the gneiss within a
space of ten acres, about two miles north of the railroad station of
Montville, on the Boonton Branch of the Delaware, Lackawanna, and
Western Railroad, and is reached by a road running north from about a
mile east of the railroad station. This road branches into two at the
limestone kilns, about a mile from the railroad track, and the left hand
branch is taken, which leads more directly to the quarry, which is on
the right hand, about a mile further on, and quite conspicuous by the
loose rock lying in front of the quarry. It is on the property of a Mr.
John J. Gordon, and produces a very fine limestone for use in the
furnaces and forges in the vicinity, as well as lime for agricultural
purposes, it being the only limestone in the vicinity for fifteen miles.
Between it and its walk of gneiss occur veins of the minerals so
characteristic of the locality, and for which it has become
famous--serpentine, asbestos, phlozopite, gurhofite pyrites, biotite,
aragonite, dolomite, tremolite, and possibly others in lesser quantity.

_Serpentine_.--All the varieties of this species, and of every color
from nearly white to black, is pro
