become chronic, and the focus of the disease is liable to break through the 

 capsule that surrounds it, and reinfect that animal at any time, and thus 

 form a new focus from which the disease may spread to other animals. 

 Hence, the farmer suspecting it in his herd 

 should at once apply to a competent veterinary 

 surgeon, if there is one within reach, to verify 

 the disease. If such expert authority be not at 

 hand; kill the animal or animals at once, slash 

 the skin to prevent any person from digging the 

 animal up for the sake of the hide, and bury 

 deeply; if quick lime can be gotten, use it freely 

 over the carcass. Then disinfect carefully all 

 stables and outhouses, and in case other animals 

 are suspected, isolate and quarantine them and 

 await developments. 



How to know it. — The earlier symptoms are 

 apt to pass unnoticed. The first is a rise in 

 temperature to 103° or 106° F., shown by intro- 

 ducing a clinical thermometer into the rectum, 

 the normal temperature being on an average of 

 101.5° F. ; there will be loss of appetite; a star- 

 ing coat; slight shiverings; a hard, dry cough; 

 a loss of milk; scanty urine, higher or darker 

 colored than usual. Then will follow tenderness 

 upon pressure between the ribs over the lungs; 

 the cough will increase; and the breathing 

 quicken; the nose will extend, the back be 

 arched; the hind legs will be drawn under the 

 body, and the elbows will be turned out. Later, 

 there will be a watery or a more pronounced dis- 

 charge of matter from the eyes and nose; obstin- 

 ate constipation, or a watery foetid diarrhoea; a 

 rapid weakening of the system, ending in death. 

 Upon percussion (striking) over the lungs, 

 there will be given back, in the earlier stages, a 

 clear resonant sound; later, it will be dull and 

 heavy. So, in the first stage, there will be a 

 dry crackling sound; later, it will be a whistling 

 Any of these may be easily distinguished Irom 

 the sound occasioned by percussion upon an animal in health. 



In America pleuro-pneumonia does not show the most violent symptoms 

 except in warm weather. Yet this very slow incubation shows the extreme
