ing generally subsides considerably in a short time, and
the glands are not in the centre of the channel, but
firmly adhere to the jaw. This is a never failing test
of the disease, and besides, it is quite certain that if the
discharge flows from both nostrils it is not glanders.
At this stage of the disease the mucous membrane
of the nostril becomes dark purple or of a livid colour,
sometimes of a tone intermediate between the two
shades. In. some instances there is inflammation of
those parts which varies from the common appearance*
being of a purple cast instead of the high red which
usually accompanies inflammation. This is followed
by the formation of small circular tubercles on the
lining of the nostrils, and these in a short time ulcerate
and discharge puss. When this has taken place, there
can no longer be a doubt that the horse is glandered,
and care must be taken not to mistake the lacrymal or
tear-duct for an ulcer. This duct is a continuation of
the skin of the muzzle, which is situated a little way
up the nostril, while the ulcerated tubercles are placed
upon the mucus membrane above the duct, and well
marked by a line of separation. After the formation
of tubercles, the animal is sure to have become con-
stitutionally affected, its coat will stare and fall off,
it will lose flesh, and its belly will be tucked up.
Cough will follow, the appetite will be much affected,
accompanied by a rapid diminution of strength, the
tubercles will multiply, discharge will be more abund-
ant, and will assume a purulent and bloody ap-
pearance, accompanied by a very foetid smell. The
ulceration will extend down to the windpipe, and the
