white. Still later, there flows from the nose either a clear and 

 thin, or a viscid and variously colored fluid. This may come 

 from the nose itself or the hronchi. In the latter it is often 

 found in masses as thick as the fniger, and great relief is afforded 

 by the expulsion of one of these. Pain is caused by pressure 

 upon the chest, behind the shoulders, or upon the lumbar region, 

 and animals show this by shrinking. 



The local signs often exist in a slight degree for weeks or 

 months without any constitutional symptoms. In the febrile 

 stage at the commencement of the disease, in strong animals, 

 the pulse is full and hard, but in those which are weak and 

 badly nourished, it is soft and full. Finally, it becomes in all 

 soft and rapid. At the commencement of the febrile period, the 

 animals stand with the back curved upward, and the head and 

 neck outstretched. In the pasture they separate themselves 

 from the herd. As the disease progresses, they almost always 

 stand with the anterior part of the body immovable. They 

 rarely lie down, and then only for a short time, either upon the 

 affected side or on the breast bone, with the fore feet beneath 

 them or stretched out in front. Towards the close, when suffo- 

 cation is imminent, they lie with the head and neck outstretched 

 and the mouth open. The hair upon the chest and neck loses 

 its lustre and stands up. The skin is dry, and is more firmly 

 attached to the withers and walls of the chest than to other 

 parts. Appetite and rumination cease entirely in the febrile 

 stage. Water excites cough, and is taken with difficulty. From 

 the dry mouth, there flows more or less viscid, dirty, offensive 

 fluid, or a frothy saliva. The milk is either secreted in small 

 quantity and is deficient in fat ; or ceases altogether. The 

 urine is dark brown, has a strong odor, and is passed with diffi- 

 culty. The fecal matter at the commencement of the disease 

 is less abundant, firm and dark brown. At a more advanced 

 period, there is either constipation, or the faeces becomes hard and 

 black, or green, watery and offensive. Abortion frequently 

 takes place, either immediately before the appearance of the 

 disease, or at the commencement and in the course of the same. 



The duration of the disease depends upon the length of the 

 chronic or non-febrile stage. If the latter be long, the disease 

 may last several weeks or months. If, on the contrary, fever 

 makes its appearance early or at the commencement of the
