attended to, and they never fail of doing well. 

 Consequently, it follows, that those attacks which 

 take place in the open air are of a milder nature 

 than those more obstinate cases we so frequently 

 meet with among in-door cattle, which serves to 

 prove, once more, our doctrine as to the cause of 

 all tumours or " tuberculous affections," as M. 

 Dupuy has it. The horses that are kept in-doors 

 accumulate gross humours, by this mode of living 

 on dry food and lying on soft beds, the exercise 

 they take not being sufficient to carry of the effects 

 of either. Enervation generally accompanies this 

 mode of treatment ; the glandular and membranous 

 part of the system suffer relaxation ; the pampered 

 animal is not exposed to the air sufficiently to oc- 

 casion that check, or slight cold, which is generally 

 the immediate cause of strangles, and the accu- 

 mulation of depraved humours proceeds, until they 

 inflame and overcome the capacity of those organs, 

 and the strangles then become a formidable dis- 

 ease. 



When this is the case, the feverish symptoms run 

 high, loss of appetite follows, with costiveness, the 

 horse can neither drink nor eat, and the pulse in- 

 creases. The tumours in these bad cases will be 

 found to have raised nearer the jawbone than they 

 do in a mild attack, and are longer in coming to 

 maturity than those which begin more towards the 

 middle. The disorder is seldom fatal ; but when 

 this does happen, the animal dies of suffocation ; in 

 which event it stands with the nose thrust out, the
