DISEASES AND TREATMENT OF THE HORSE 105 
in some cases is of a yellowish color. In order to tell whether 
the sinuses are much affected tap on the bone over the 
sinuses with the finger; if this makes a dull sound as if the 
sinuses were full, you may conclude that they are diseased ; 
but if a hollow drum-like sound, you may come to the con- 
clusion that the sinuses are not much affected and there is 
more hope of recovery. As the disease continues, the animal 
becomes very much weaker ; the discharge has a very bad 
smell, showing that the bones of the head are becoming af- 
fected. If a bad tooth is causing the trouble, the discharge 
comes only from one nostril. He will not eat very well ; 
sometimes, after taking a bite, he will throw the food out of 
his mouth. The breath has a very bad smell and the horse 
will soon run down in condition. To distinguish this disease 
from glanders, notice first, that the discharge in glanders is 
of a greenish color and will sink in water, while the discharge 
in nasal gleet will float on water; second, the lining inside 
of the nose, if the animal has glanders, will be covered with 
• small ulcers. Again, the temperature in suffering from nasal 
gleet will be about normal, but if from glanders will run as 
high as 103° or 105°. In doubtful cases you might even 
apply the Mallein Test, fully described in Chapter XV. 
Treatment. — This disease is not, as a general thing, 
easily treated. If the animal is thin and run down in condi- 
tion, it is well to build him up with good food, regular exer- 
cise, pure air and the following mixture: 
Mix thoroughly and give a teaspoonful twice a day, night 
and morning, on his tongue or in his feed. Wash the nostrils 
twice a day with warm water. If you conclude that the 
sinuses are much affected or that some food or foreign sub- 
stance is causing the trouble, the treatment will then be dif- 
ferent. The animal should be thrown and secured with a 
rope. Strip a piece of skin about an inch in diameter from 
the bone with a knife and with a trephine bore a hole through 
'the bone into the sinuses. This is easily done, the bone at 
this point being thin and soft. Little pain is caused and but 
little risk of danger is run. See fig. 3. When the hole is 
made the pus will discharge and with it generally comes the 
cause of the trouble. Make the hole as near the lower part 
of the sinus as possible so as to allow the discharge all tQ
