ENZOOTIC DISEASES. 205 



tions of the heart are loud, so as to be heard on applying the ear 

 to the ribs ; the pulse is feeble, the appetite irregular, and a slight 

 cough exists, caused by the efforts to throw off the accumulating 

 and offending matter from the lungs. In time, the glands of the 

 body become loaded with the deposited matter ; those of the throat 

 and neck, the parotid and submaxillary, being most commonly 

 and extensively affected, and greatly swollen. The symptoms 

 gradually increase in intensity, and there is much fever and ema- 

 ciation, with discharge from the nose and eyes. The skin is tight 

 and pale, and the body appears almost free from blood, as in 

 anaemia. At this period there is no help for the animal, for death 

 is only a question of time. 



The treatment in the earlier stages is to administer some of the 

 preparations of iodine, such as the following : 



Iodide of Potassium 5 grains. 



OB 

 Iodide of Iron 10 grains. 



to be finely powdered and mixed with molasses, and placed on the 

 root of the tongue, so that it is swallowed. The above dose to be 

 given daily. The latter preparation is to be preferred. The 

 swellings may be rubbed daily with iodine ointment. No scrofu- 

 lous animal should be used for breeding, as the disease is heredi- 

 tary. High-bred sheep are the most subject to this disease, and 

 "in-and-in breeding" tends greatly to produce it. 



In some localities an enlargement of the glands of the neck, 

 similar to the disease known as goitre in mankind, is frequent 

 amongst sheep. This is supposed, doubtless viA reason, to be 

 caused by the water drank, as in such cases the "emoval of the 

 flock to distant pastures has led to the disappearance of the dis- 

 ease. The occurrence of the symptoms above described, however, 

 will be sufficient to indicate the true character of scrofula as dis- 

 tinguished from any accidental swelling of the glands. 



iJropsy consists in the effusion of a watery or serous fluid in the 

 abdomen. It is accompanied with inflammation < f the lining 

 membrane of the abdomen, the peritoneum, f roi '\ which the fluid 

 is secreted. It is caused by feeding upon rank, succulent, watery 

 herbage, by which the blood is insufT. .iently nourished. A 

 change to dry food, or scanty but more nutritious pasture, allevi- 

 ates the disease at once. A cure is jcnerally effected by the use 

 of diuretics, aperients, and tonics. ^ le treatment will be the ad- 

 ministering of the following, or such others as may produce the 

 4esired effect:
