BEONCHITIS. 255 



more especially should this be the case with dairy people i 

 for when anything in the least unusual is discovered, such 

 as a very slight grating sound in the wind-pipe when the 

 ear is steadily applied, the cow should immediately have 

 some iron, or tonic powders, and all will be well in a few 

 days again ; whereas, if left to itself, serum is exuded, and 

 debility, weakness, and even death may follow. I would 

 say to dairy men, study the sounds in the wind-pipe, both 

 in the sick and well animal, and you will not only perfect 

 your knowledge in this particular, but I assure you it 

 will be no idle study ; for in a short time you will not only 

 be able to detect these insidious diseases, in the beginning, 

 in your cows, but can apply the remedy also, thereby 

 saving yourself from inconvenience and loss, which some 

 can ill afford. In this way, you can prove to your neigh- 

 bors, and to the world at large, that cattle diseases are 

 not so difficult to cure after all, and that while others have 

 so long sat and brooded with soured and sullen minds over 

 their losses, and the ignorance and inefficiency of cow doc- 

 tors, you have obtained a mastery of the situation. 



Cause. Bronchitis is a disease which rarely attacks one 

 animal only, but usually the most of the herd will have 

 been attacked before it leaves tlie place, and then it will 

 leave when there are no more victims to seize. These 

 epizootic diseases depend upon what is called atmospheric 

 causes. Such condition usually manifests itself in the 

 spring of the year, and sometimes early in the summei*. 

 The peculiarity of the air causes irritation of the fauces of 

 the mouth, throat or wind-pipe, and, as before stated, 

 sometimes extends to the chest and lungs themselves. 



Symptoms. In a week or so after the attack, a slight 

 husky cough, with weeping from the eyes, and a watery 

 discharge from the inner corner of the nose, will be seen;
