 AFFECTIONS OF THE DIAPHRAGM. 



SPASMS OF THE DIAPHRAGM. 



This is caused by over-exertion when the animal is in unfit con- 

 dition. Its most prominent symptom is a convulsive motion, or 

 jerking of the whole body, accompanied by a dull, thumping- 

 sound. The diaphragm is a thin, fan-shaped muscle, separating 

 the thoracic cavity from the abdominal. It is situated posterior 

 to the heart, and at once indicates the difference between the 

 spasms or thun^ps of the diaj)hragm and cardiac palpitation. 



Treatment.- — All that is necessary is the administration of an 

 ounce of alcohol and clothing of the body. If several doses of 

 alcohol be necessary, they should be given every four hours. 



RTJPTUIIE OF THE DIAPHRAGM. 



Rupture of the diaphragm is said to have taken place. I have 

 never met with this lesion, and therefore do not know the symp- 

 toms jiresented.
