DISEASES AND THEIR TREATMENT. 



(schneiderian) is altered in color ; it becomes of a pale leaden hue, 

 but does not exhibit ulcerative patches, as in .glanders. The dis- 

 charge may vary both in quantity and quality. It is often retained 

 for some time within the sinuses, and comes away in considerable 

 quantities. In other cases the discharge is continuous, and collects 

 about the nostrils ; the sub-maxillary gland, in cases of long stand- 

 ing, becomes tumefied, but not adhering to the bone as in glanders ; 

 the frontal and nasal bones are affected, and present an enlargement 

 or bulging out over the seat of the disease. If 

 tapped with the point of the finger, a dull, heavy 

 sound is produced, showing that matter has. col- 

 lected within the sinus. In ordinary cases it is a 

 long time before it materially affects the horse in 

 his working capacity. When the bones are greatly 

 diseased, and the matter collects within the nasal 

 sinuses, it interferes with respiration, causing la- 

 borious breathing. 



Treatment. — Although a formidable disease, even 

 the worst of cases may recover if properly treated. 

 The successful treatment in all cases where this dis- 

 order has existed, has been on the tonic principle. 

 Bleeding and purging are positively injurious. Give 

 good food and moderate exercise, sponge the nos- 

 trils with tepid water, or steam the head, as des- 

 cribed for catarrh, once or twice a day, and administer mineral or 

 vegetable tonics, as — 



Sulphate of copper , 3 oz. 



Powdered gentian 1 oz. 



Make into twelve powders, and give one in the food morning 

 and night ; or, the sulphate of iron in two-drachm doses twice a day. 



The nasal cavities may be injected with a weak solution of sul- 

 phate of zinc or of alum ; or of sulphate of copper, about five grains 

 to an ounce of water. When the bone is diseased, and matter col- 

 lected within the sinuses, it is necessary to trepan the bone. After 

 Operating, inject the sinus with tepid water twice or thrice a day, 

 followed by injecting any of the astringents already recommended. 

 The opened sinus sometimes fills up with a fungus growth, which 

 must either be removed by the knife or by means of caustics. 



I include here treatment reported in the Journal of Compara- 

 tive Medicine and Surgery for January, 1883, by John Lindsay, 

 D. V. S., of Huntington, Long Island, which has been so effective 

 that I think it worth while to copy his report in full • —
