 triHing dental asperities, or some equally simple measure, will 

 suffice to confer marked benefit. At otlier times, however, 

 when more closely dependent on disturbance of nerve-power 

 or lesion of nerve-tissue, the progress of the disturbance may

 every instance we have to remember that the nervous dis- 

 turbance upon which it depends, where this can be made out, 

 demands our attention rather than the mere symptom of 

 salivation.

DISEASES OF THE THROAT. 



Diseases of the throat, chiefly of the Uning membrane and 

 immediately associated structures, are common in the horse 

 at all ages ; usually appearing at some part of the course 

 of epizootic catarrhal fever, and other specific affections in 

 which the air-passages are involved. It is, however, as inde- 

 pendent affections, not as part of the general symptoms of 

 either influenza or strangles, or any other fever, which we now 

 speak of them. 



I. Acute Pharyngeal Catarrh. — Inflammation of Fauces 

 AND Pharynx. 



Definition. — Common inflammation of the textures, chiefly 

 mucous onemhrane and submucous tissue of fauces and 

 'pharynx. 



Pathology, a. Nature. — Under the designation of inflam- 

 mation of these structures may be grouped many cases of 

 sore throat, sudden in accession, unattended with fever, and 

 which in a few days terminate in resolution. The abnormal 

 action is of a congestive or inflammatory character, with 

 oedema of the Hning membrane of the fauces and pharynx, 

 the one situation being rarely affected apart from the other.
