W THE PRACTICE OF VETERINARY MEDICINE. 



but I will describe a case as it occurs in the usual form as 

 a result of ordinary causes. A horse suffering from catarrh 

 has been driven, is rubbed over and put in the stable ; he 

 is observed to shiver, the body becomes very cold, in some 

 cases the extremities also become deathly cold ; all food is 

 refused ; on auscultation rhonchus rale is discovered ; the 

 mouth is hot, more or less constipation is observed, pulse 

 sixty, seventy, or eighty beats per minute ; as a rule the 

 patient persists in retaining a standing position ; in some 

 exceptional cases, vfhere tympanites occurs, the animal may 

 lie down to relieve the intestinal pain ; the breathing is 

 quickened, and somewhat difficult in most cases. 



A horse, after being driven a few miles, more especially 

 if at a sharp pace, and the animal not in fit condition, will

 is reddened, breathing becomes very difficult, the nostrils

 characteristic, and is a valuable diagnostic symptom. Cold 

 sweats bedew the body, and the body, ears, and extremities 

 become deathly cold (in warm weather the coldness of the 

 body, ears, and extremities is not so well marked as during 

 cold weather), the ears flap, or droop, in some cases the 

 pulse is indistinct, in other cases not so much so ; the 

 temperature gradually rises, there is trembling of the 

 flanks, and on auscultation the characteristic sounds of 

 congestion of the lungs are heard. Allow the animal to 

 stand quietly, and he will often recover ; but drive him in 

 this condition and death will result. 



Treatment. — The treatment of congestion of the lungs is 

 not at all difficult, and if proper, the result is usually 

 satisfactory. The treatment should be energetic ; whatever 

 it is intended to do, should be done without loss of time. 

 A diffusible stimulant should be given as soon as possible, 

 as spts. reth. nit., or neth. sulph., in doses of 5i. — 5ii., the
