 long as the animal can do without it, and when the 

 breathing becomes difficult, resume again and so

 the lungs. This disease is caused by injuries to the 

 walls of the chest, or from exposure to cold when 

 the animal has been heated. I have seen a num- 

 ber of cases following clipping late in the fall or 

 too early in the spring. It is often connected with 

 pneumonia and disease of the heart. It sometimes 

 takes place without any apparent cause and is
