SYMPTOMS. 463 



to those of the first class in particiihir, and somewhat re- 

 strictively, that these terms have usually been applied, the 

 others being recognised by having added to them the name of 

 the locality from which the discharge is supposed to proceed ; 

 thus we speak of discharge from, or collections of matter in, 

 the frontal sinuses, the turbinated bones, or the eustachian 

 pouches. 



Symptoms. — When the causes of the discharge seem specially 

 connected Avith changes in the great nasal chambers — nasal 

 gleet properly so called — it is not common that the original 

 flux connected with the primary and actively diseased mucous 

 membrane — we speak noAV of those cases which succeed ordi- 

 nary catarrh — has disa23peared ; usually we find that this has 

 become for a time less in amount and considerably altered in 

 character ; it is less purulent than when the original catarrh 

 continued. When of some time standing it is of a glairy 

 starchy character, with occasionally flakes of inspissated 

 mucus or pus mingled with the more liquid portions ; and, 

 although it may be more plentiful some days than others, it 

 seldom intermits altogether. 



When connected merely with lesions of the membrane of 

 the great nasal cavity, it has rarely a foetid smell. Although 

 the constitutional disturbance may never be so great that the 

 appetite is impaired, it is seldom that we do not discover some 

 slight appearance of impairment of the general health. There 

 is often an unthrifty open condition of the coat, with a scurfy, 

 unhealthy state of the skin ; the animal wants bloom and 

 vivacit}^ particularly while at work, and is soft and easily 

 fatigued with even a slight amount of muscular exertion. On 

 a closer examination there may often be detected a condition 

 of fulness and induration of the submaxillary glands, while 

 the pituitary membrane, which in health and during the con- 

 tinuance of the active catarrh was bright pink or of a red colour, 

 is somewhat altered, being less vascular-looking, of a slate or 

 leaden hue, with, it may be, a rather soft, blanched, and some- 

 what thickened and infiltrated appearance. 



Treatment. — In every case of confirmed chronic nasal catarrh, 

 imtil we are thoroughly satisfied that the discharge with which 

 we are dealing is not glanderous, and not likely to propagate 

 itself, we must be careful to maintain strict isolation of the
