In the third stage, if the disease is going to terminate favorably, the 

 cough becomes loose; the animal improves; the appetite returns, and 

 the symptoms above detailed rapidly subside. But if, on the other 

 hand, resolution is not progressing, the lung substance is broken down, 

 is heavy, and will sink in water. In fatal cases the breath has a pecu- 

 liar fetid, cadaverous odor, and is taken in short gasps; the horns, ears, 

 and extremities become cold and clammy, and the pulse is imperceptible. 

 On ausculation, when suppuration is taking place and the lung structure 

 is breaking down, a bubbling or gurgling sound caused by the passage 

 of air through pus, will be heard. 



Treatment. Good hygienic surroundings and good nmsing are 

 essential in connection with the medical treatment. The probability of 

 cure depends largely on the extent of the lung tissue involved, as well 

 as on the intensity of the inflammatory process. In the early stage, 

 when the fever is high, give febrifuges. If the pulse be strong and 

 full, aconite (Fleming's tincture, two to five drops every four or five 

 hours) may be given for a short time, but should be discontinued as soon 

 as the fever begins to abate. Aconite is a valuable drug in the hands of 

 the intelligent practitioner, but my experience leads me to believe that 

 not infrequently animals are lost by its injudicious use. For in many 

 febrile conditions it is positively contra-indicated, owing to its action 

 upon the heart. In a plethoric animal, with a strong bounding pulse, 

 bleeding may be resorted to instead of administering aconite. If the 

 bowels are constipated give calomel, one to three drams, which acts as 

 a cathartic and a febrifuge, In the second stage diffusible stimulants 

 are required, viz: spirits of nitrous ether, two ounces; spirits aromatic 

 ammonia, one ounce. Mix and give in gruel three times daily. If 

 the above is not at hand, give an alcoholic stimulant. Half a pint 

 of brandy or whisky may be given in a quart of gruel three times 

 daily. In some cases carbonate of ammonia, two to five drams, has 

 been found beneficial. Most practitioners apply counterirritants exter- 

 nally, such as mustard plasters, turpentine, and ammonia liniment, 

 or cantharides. 



Bronchitis. Bronchitis is an inflammation of the mucous membrane 

 of the bronchial tubes. When a primary disease it is generally the result 

 of what is commonly known as "catching cold." It may be secondary 

 to or complicated with many of the diseases of the respiratory system. 

 It may also be caused by breathing irritating gasses, or by the introduc- 

 tion of foreign bodies into the bronchial tubes, which sometimes result
