_Symptoms._ The general symptoms being like those of _Laryngitis_, the specific and distinguishing ones only will be here noticed. The larynx is not tender to the touch nor is cough thereby excited. The glands beneath the root of the ears (parotids) are swollen and tender and cough is induced by handling them. The intermaxillary glands are enlarged. The cough is loose and followed by the ejection of glairy materials by the mouth and nose. Food and drink are swallowed with difficulty and effort, dry grain or hay is often refused, or dropped from the mouth, after it has been chewed, to avoid the pain of swallowing. Deglutition is accompanied by a gurgling sound caused by the abundant secretion in the pharynx. In swallowing liquids a portion is often rejected by the nose. The mouth is hot, red at its back part, and filled with fetid saliva which often drivels from between the lips in the coarser breeds of horses. The fever varies according to the intensity of the inflammation. This disease is rarely serious, and improvement is manifested, by a free discharge from the nose of a white opaque color, by the ability to swallow without pain, and the better appetite and general appearance. Collections of pus in the _Guttural pouches_ may result from pharyngitis. See _Chronic Nasal Catarrh_. Reynal has seen chronic cases of this disease due to: 1st, fracture of the large branch of the hyoid bone; 2nd, Laceration or ulceration of the soft palate; and 3rd, an abscess of the pharyngeal mucous membrane. The _treatment_ does not differ materially from that of laryngitis except in the greater value of soft food, mucilaginous and acidulated drink and of electuaries which act on the throat as they dissolve.
