hogs. It is from 1 to 1.5 inches (25 to 27 mm.) long, and when seen against
the kidney fat it appears dark or mottled. It is usually found in the fat
in the region of the pelvis of the kidney. Although the kidney worm is
capable of causing inflammatory changes in the tissues surrounding the
kidney and the pelvis of this organ, the disease cannot be determined by
any noticeable symptom. Paralysis of the posterior portion of the body is
attributed to the presence of kidney worms by stockmen. There are no data
by which we may prove that the kidney worm is responsible for this
disorder.

_The treatment_ is preventive. Clean feed, pens, watering troughs and
feeding floors are the preventive measures indicated here. It is useless to
attempt treatment with drugs, as the worms are out of reach of any drug
that may be administered.

WORMS OF THE DIGESTIVE TRACT OF POULTRY.--Poultry are often seriously
infested with worms. A small number of the less injurious worms may not
cause any appreciable symptoms of disease; but the fowl that harbors them
is a source of infection to the other fowls. The infectious nature of
parasitic disease caused by worms should be recognized more fully than at
present by poultrymen.

The different species of poultry are hosts for many different species of
round-worms, thorn-headed worms and tapeworms. Dr. Kaupp states that
_Acaris inflexa_ or large round-worm, _Heterakis pipilosa_ or small
round-worm, and the _Spiroptera hamulosa_ or gizzard-worm are frequently
found in fowls. The common round-worm may be found in the first portion of
the intestine, and the small round-worm in the caecum. Neither of the
species are dangerous unless present in large numbers. They may then
obstruct the intestine, and irritate the intestinal mucous membrane. This
