ends in 1 recovery in seven to fifteen days, in cases that are not 

 complicated by dangerous local infections. 



Diagnosis is mainly based on the stiff carriage of the neck 

 with the nose elevated, the swelling and tenderness of the throat, 

 manipulation above the larynx rousing the cough, the soft or 

 rattling nature of the cough, the ejection of liquids and foods 

 through the nose, the movements of the jaws apart from masti- 

 cation and the salivation. From parotitis it is distinguished by 

 the concentration of the swelling and tenderness to the deep- 

 seated region above the larynx, by the abundance of the dis- 

 charge, by the ejection of liquids through the nose, and by the 

 readiness with which the cough is aroused. From abscess of the 

 guttural pouch it is differentiated by the more continuous discharge 

 from the nose, rather than the intermittent one. From tuberculous 

 pharyngeal glands by its acute nature, by the absence of the 

 glandular swellings in which the tuberculosis is concentrated, also 

 by the absence of tubercles in other parts of the body. From 

 actinomycosis by its more rapid progress and by the absence of the 

 hard indurated cutaneous or subcutaneous swellings, and of the 

 ■open sores with minute sulphur colored granules that mark that 

 affection. From adetiitis and phlegmonous pharyngitis it is dis- 

 tinguished by the absence of the glandular swelling and dyspnoea 

 which attend on that affection . From the various iaXaX febrile affec- 

 tions, the germs of which may be localized in the throat, it may be 

 diagnosed by the absence of the more profound constitutional 

 disturbance, and of the more characteristic local symptoms of 

 these which are seldom altogether awanting, though often greatly 

 modified. 



Lesions. Beside the thick covering of . muco-purulent and 

 alimentary matters, the pharyngeal mucosa, when washed, shows 

 redness, ramified or reticulated, more or less swelling amounting 

 at times to oedema, a soft friable consistency, which like the 

 oedema may in bad cases extend into the submucous tissue, granu- 

 lar elevations, and raw abrasions caused by the destruction and 

 removal of the epithelium. In some instances the ulcers may 

 become quite extensive. 



In the more specific inflammations (tubercle, glanders, rabies, 

 aphthous fever, contagious pneumonia, anthrax, actinomycosis), 

 the lesions will vary according to the specific nature of -the 

 disease.
