INFECTIOUS PHAEYNGITIS 27 



the disease. In exceptionally severe cases, showing great 

 tumefaction in the region, considerable dyspnea may 

 occur. Hardly ever does it become so serious as to re- 

 quire the performance of tracheotomy. 



There is no discharge from the nose in most cases 

 until the dysphagia is fully established. It is then of 

 a muco-purulent character, and not very copious. This 

 would indicate that the discharge is chiefly the result of 

 an irritation of the Schneiderian membranes as a result 

 of contact with water and food particles that flow 

 through the nasal chambers. Cases that develop an 

 abscess in the pharynx have a liberal purulent nasal 

 discharge. On account of the inability to take sufficient 

 nourishment the affected animals lose considerable 

 weight. The patients maintain a standing position 

 throughout the course of this disease. 



I wish to call especial attention to what I have said 

 about the order in which the ingested matter is rejected 

 by the pharynx in this disease, namely, 



1. Water. 



2. Grain. 



3. Hay. 



This is always the order of sequence in this disease; 

 and did we have no other single mark by which to differ- 

 entiate this disease from other forms of pharyngitis, we 

 would be able to recognize it thereby. To me this is also 

 positive proof, in the absence of satisfactory bacterio- 

 logical evidence, that this disease is not in any way allied 

 to influenza. It is evidence that the dysphagia is not so« 

 much the result of an active inflammatory lesion in the S^ 

 pharynx at first, but more probably the result of a sec- 

 ondary trophic disturbance. Were the dysphagia the 

 result of a highly inflamed, painful state of the pharyn- 

 geal mucosa and surrounding tissues, we have every rea- 

 son to believe that the order of rejection would be re-
