LUNG Disease. Cattle are subject to an infectious lung 

 disease ; goats have been found liable to a disease of 

 the same nature at the Cape ; and the Author has proved to his 

 satisfaction that sheep also take lung disease one from 

 another, and die, under certain circumstances, in great 

 numbers. It appears to possess very much the nature of a 

 bad cold, and is more severe on old ewes and lambs than on 

 other sheep. Should it break out in a flock during summer, 

 or in fine mild weather in winter, deaths are not numerous ; 

 but in a cold and stormy season, which aggravates the 

 disease, one-third to one-half is no unusual proportion of a 

 flock to die. 



The symptoms are a violent and painful cough, which 

 seems to give no relief. When seriously affected, the animal 

 falls off from the others, and gradually stops feeding. The 

 breathing becomes increasingly heavy and laboured, with 

 heaving at the flank, and moaning in the later stages, 

 evincing the presence of acute bronchitis with severe pain. 

 The ears droop in a peculiar manner, and the head hangs 

 down, while foam appears at the mouth, and a tough yellow 

 mucus at the nose and eyes. None recover after these 

 acute symptoms set in, and death supervenes generally 

 about the third or fourth day. The post-mortem reveals a 

 highly congested state of the air-passages, and large portions 

 of the lungs, usually the upper lobes, are found to be 

 solidified, so that they sink on being immersed in water. 



The most efficacious treatment is to inject by the intra- 

 tracheal syringe, shown at page 239, 2 to 4 drams of 

 the injection mixture there detailed, and to cover the backs
