 conceivable locality, manner of feeding, and quality of drinking 

 water, we become dumb-founded in its contemplation. To make 



matters worse, it 

 chooses for its prey

 mals. I believe 

 that it is conveyed 

 into t h e system 

 from the air. By 

 chemical analysis of 

 the various tissues 

 of the diseased

 with those of the 

 soil, vegetation and water of the surroundings, we may discover 

 the cause and its origin. 



Symptoms. — I will first give the symptoms of that form of the 

 disease met with during the heated months of the year. The first 

 symptom is dullness. The animal drives duller than usual. If 

 this symptom is noticed during the 

 outbreak of the disease, the animal 

 should at once be taken to the 

 trough to drink. First remove the 

 bridle, and get in a position to see 

 him take the first swallow. If he 

 sips two or three times before swal- 

 lowing, then succeeds in swallow- 

 ing a small quantity, and finishes 

 his drink in the regular manner, 

 swallowing after each draw, the 

 poison is in his system. The dis- 

 ease at this stage can be treated as successfully as a bad cold.

 two or three days he will stumble occasionally, may fall but
