opening of the bowl, then passes the tube a good way up 

 the nostril, applies his mouth to the covered bowl, and blows 

 vigorously through the handkerchief. When this has con-

CORYZA. 



During the winter season this disease is very common 

 •with sheep that are wholly, exposed, or when shelters are 

 imperfectly constructed. The chief annoyance is occasion- 

 ed by an excess of mucus, ^hich clogs the nasal passages, 

 and causes great difficulty of breathing. When a sheep is 

 in this siOiation, it is said to have a " bad cold." In some 

 cases,.unless relieved, the sheep will sometimes die from 

 suffocation. At other times the inflammation will extend to 

 the bronchial tubes, and pulmonary consumption (rot) will 

 ensue. 



Treatment. — Removal to a warm shelter, and a dose oi 

 purgative medicine, is all that will be required. The efforts 

 of nature, however, are sufficient to remove the disease, 

 when the attack is slight. 



The preventive, which is always worth the pound of cure, 

 are good shelters, and wholesome food. 



DISEASES OF THE STOMACH AND INTESTINES. 



HOOVE, OR •DISTENSION OF THE STOMACH BY GAS. 



This cannot be considered a disease, but an impediment 

 of respiration and circulation. It is occasioned by the sheep 

 being changed from a poor pasture -to a luxuriant one, and 

 gorging itself to an immoderate degree. The gullet is ob- 

 structed, and the gases in the paunch cause remarkable dis- 

 tension, with no passage for their escape, except into the 

 chest, which ends in suffocation of the animal. 



Treatment. — An aperture is sometimes made, with a sharp 

 instrument in the side to permit the passage of the gas ; but 

 this Blacklock explicitly condemns. . The remedy is the 

 prohang, a flexible rod, with a small ball of wood or ivory at 

 the end, which, being forced to the lower extremity of the 

 gullet, removes the obstruction, and the gas or wind is 

 readily voided.
