846 BUILDINGS, SANITATION, AND DISEASES 
Turpentine is commonly recommended for worms, especially 
the thorn-headed worm. The dose is a teaspoonful for every 
eighty or one hundred pounds live weight of the hogs to be 
treated. It can be given in the feed, and the hogs should be 
fasted at least twelve hours before treatment. A dose each day 
for three days will generally prove effective. 
Another remedy which is recommended is five grains of 
calomel and eight grains of santonin for every hundred pounds 
live weight of the hogs. This remedy ean also be given in the 
feed. It is generally advisable to give a physic after treatment 
for worms. 
LUNG WORMS. 
The lung worm is a small, thread-like, whitish worm, some- 
times found in large numbers in the air-passages of the lungs. 
Ordinarily, about the only symptom is a spasmodic cough, 
which is somewhat similar to the cough which accompanies 
bronchitis. Sometimes the irritation caused by the worms 
produces inflammation and consolidation of the lung tissue, 
in which case the animal dies, but in many cases no bad effect 
is apparent. In a post-mortem examination, the wormns can 
be detected by cutting the lung near the apex and then squeez- 
ing the tissue next to the cut. The pressure forces the thread- 
like worms out upon the cut surface. 
There is practically no effective treatment for this parasite. 
Clean pens, in which disinfectants are liberally used, and clean, 
well-drained vards will help keep the worm in check. Filthy 
yards and wallows favor its development. Ploughing up old 
hog lots and re-seeding them is also a preventive measure.
