12G GLANDERS AND FARCY. 



nose and nasal structures, but chiefly from the extension of 

 the destructive and ulcerative action to the larynx and lar}Tigcal 

 structures, this diseased process being invariably marked by 

 extensive infiltration and thickening of membranes and tissues. 

 In these instances there is usually frequent and painful cough, 

 and tenderness on manipulation of the laryngeal region. 



The pneumonia and bronchitis attendant on acute glanders 

 are often overlooked ; they may, however, be made out to 

 satisfaction by careful physical examination of the chest. 

 These conditions, when existing, appear to be intimately con- 

 nected with the formation of the glanderous nodules in the 

 pulmonary tissue, and the circumferential infiltration attendant 

 on this condition. When the lung-tissue becomes involved, 

 exhaustion is rapidly progressive ; the appetite, which may for 

 some days have only been capricious, is now gone ; dyspnoea 

 from pulmonic changes and blood-poisoning becomes distress- 

 ing ; while oedema of the inferior parts of the body and specific 

 cutaneous infiltration ensue. Life is rarely prolonged beyond, 

 twenty or thirty daj's. 



2. Symptoms of Chronic Glanders. — Glanders in a chronic, 

 or at least not in an acute fonii, is the manifestation of the 

 disease we most frequently encounter in this countr}''. In this 

 form it may continue for many months without making 

 marked inroads on the animal's constitutional health and 

 vigour, or by very obvious symptoms proclaiming the estab- 

 lishment of the fatal disease. 



As in the acute form, Ave may regard the symptoms as par- 

 taking of the same double character, constitutional and local. 

 In chronic glanders, the local phenomena are certainly the 

 more important, from being the specific ; they are also the 

 more numerous. The constitutional, besides being more 

 trivial, are also not invariable, and are dependent for their 

 existence or character on varying surrounding conditions. 

 Unlike the acute form, the chronic is more apt to develop 

 constitutional symptoms, at the latter, rather than the earl}'-, 

 stages of the malady. 



The diagnostic features in chronic glanders are the local, 

 and are connected with : («) changes in the nasal chambers ; 

 (h) with alterations or changes in the lymphatic vessels and 

 lymphatic glands.
