CATARRH. 19 



through proper management recovers so far as to be on the 

 eve of returning — or has actually returned — to his work, and 

 then becomes attacked with bronchitis or pneumonia, it is 

 very apt to go harder with him than had the attack of pneu- 

 monia shown itself at the first. Many a horse has changed 

 hands having at the time a simple ^' cold/^ which in his new 

 owner^s possession has run into an attack of bronchitic pneu- 

 monia, wherefrom, should he escape with his life, there is still 

 great risk of his becoming a roarer. Catarrh may prove but 

 the precursor of strangles. But again, cases do occur, though 

 happily for us but rarely, wherein the disorder, after having 

 run its course, and cast off all signs of inflammatory action, 

 leaves a discharge from one or both nostrils, to which we give 

 the name of nasal gleet ; and the appellation is applicable so 

 long as the defluxion presents nothing beyond the catarrhal 

 character : from the moment, however, that it loses this, and 

 especially when it has turned to a thick, turbid, dingy-look- 

 ing mucus, clinging to the nostrils of the horse, and sticking 

 with gluey tenacity to the fingers of the person inspecting 

 them, we must — should we not have done so before — take 

 care to remove the animal into a stable or box apart from 

 other horses ; and at the same time advertise his owner 

 of our suspicions of his ultimately turning out glandered. 

 This, however, is a part of our subject which cannot be properly 

 understood until the diseases, ^' nasal gleet^^ and " glanders,^^ 

 come to be taken into consideration. 



Prognosis. — Of itself, a catarrh is a harmless, painless dis- 

 ease, often so mild as hardly to call for medical interference, 

 and never resisting judicious counter- agency for any very 

 long period of time. It is only from its sequelae that adverse 

 results, and occasionally even fatal consequences, are to be 

 apprehended : I mean bronchitis, roaring, nasal gleet, and 

 glanders. 



Pathology. — Observations in this field of veterinary prac- 

 tice are well calculated to throw a light upon one or two 

 extremely interesting and still disputed points, touching the 

 cause and nature of catarrh in general. I have already 

 endeavoured to show, from results of every day occurrences,
