62 THE VETERINARY SCIENCE. 



disease runs on, the animal gets very much weaker, the discharge 



has a very bad smell; this shows that the bones of the head are 



becoming" affected. If it is a bad tooth that is causing the trouble, 



the discharge will only come from one nostril; the animal will not 



eat very well; sometimes he will be noticed, after taking a bite, to 



throw the food out of his mouth. The breath has a very bad 



smell and the horse will soon run down in condition. The way to 



distinguish this disease from glanders is 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, by examining 



the lining inside the nose which, if the animal has glanders, will 



be found to be covered with small ulcers. 



Treatment. — This disease is not, as a general thing, easily 



treated. If the animal is thin and run down in condition, it is 



well to build him up with good food, regular exercise, pure air and 



the following mixture : 



Ground Sulphate of Iron ^ pound. 



Ground Sulphate of Copper i pound. 



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 substance is causing the 



trouble, the treatment will then be different. The animal will have 



to be thrown down and tied with a rope, securely, then strip a 



piece of skin as large as a copper off the bone with a knife, and 



take a trephine or an inch auger and bore a hole through the bone 



into the sinuses, which can be easily done for the bone is soft and 



thin and does not cause much pain to the animal, and can be done 



with very little risk. When the hole is through the discharge will 



come out of it, and with it will generally come the seat of the 



trouble. Keep the hole open as long as you can by passing your 



finger into it, and also injecting warm water with a few drops of 



carbolic acid into it with a syringe once a day ; use 10 drops of 



carbolic acid to the pint of water. If the disease is caused by a 



bad tooth, have the tooth pulled out, and follow up with medicines 



mentioned above. 



ABSCESSES OF THE BONES OF THE HEAD. 



The only treatment is to bore a hole with a trephine or auger 

 through the bones of the head into the abscess, allowing the 

 matter or discharge to escape. Inject into the hole with a syringe
