DISEASES OF RESPIRALTURY PASSAGES AND ORGANS. 99 
Cove IN rts CHRONIC AND ACUTE STAGE. 
A-cording to veterinary jurisprudence, a cough, so long as it 
sasts, renders the animal unsound; hence it is very important that 
we should know something about its cause, nature, and treat- 
ment. (uronic cough is often the result of indiscretion in the 
treatment of influenza, distemper, and disease of the respiratory 
apparatus. It usually depends on a morbid and irritable condition 
of the membrane found on the interior of the respiratory passages. 
The cough is generally aggravated by over-exertion, especially 
when the roads are dusty. Food of an inferior quality, and that 
of a musty character, has the same effect. 
It is generally supposed, by those persons who have not had the 
venefit of a medical education, that the presence of acute or chronic 
cough indicates diseased lungs, or disease in some parts of the 
organs of respiration. But this is not always the case; for, when- 
ever the liver becomes diseased, the subject is very apt to be tor- 
mented with a harrassing cough, which lasts as long as that orgar 
shall be the seat of disease. However, there are several symptoms 
to be observed in cases of functional or organic disease of the liver 
which are not present in lung disease; hence there is no difficulty 
in the way of making a correct diagnosis. And for the benefit 
of the non-professional, the author would inform them that, in all 
vases of liver disease, a marked yellow tinge will be observed on 
the visible surfaces within the mouth; the tongue slightly coated ; 
the dung unusually dark colored, and voided in hardened lumps, 
wid the urine also of a dark yellow color. 
Treatment of Chronic Cough.—Give the patient daily one ounce 
ef the fluid extract of Indian hemp (foreign), and offer him occa- 
tionally some ilaxseed tea; or sprinkle in his food, every night, a 
handful of unground flaxseed. Should this fail to effect a cure, 
prepare the following:
