ACUTE CATARRHAL BRONCHITIS. 481 



a powder, one or two of which care given daily in the food, is a 

 coHA'enieut form. Or a very excellent ball may be compounded 

 of half a drachm of powdered sulphate of iron, the same 

 quantity of nux vomica, and one drachm of p)owdered gen- 

 tian, with linseed-meal and treacle sufficient to give bulk and 

 consistence. This may be given daily, or morning and even- 

 ing ; or it may be alternated with^ another composed of a 

 drachm each of powdered camphor, gentian, myrrh, and ginger. 



In the management of cases of mechanical bronchitis, much 

 discrimination is needed. It is futile attempting by heroic 

 measures to cut short the diseased action ; we must endeavour 

 to moderate its intensity. The employment of simple salines 

 in the drinking-water, or the exhibition, where this is attain- 

 able, of the febrifuge draught recommended for ordinary bron- 

 chitis, with an extra quantity of the solution of the acetate of 

 ammonia, are more likely to be attended with benefit. If we 

 can only enable the animal to pass over the earlier stages, and 

 maintain strength enough to enter upon those attended with 

 mucous rale and soft, frequent cough, there will be reasonable 

 hope of an ultimate recovery. 



With complementary bronchitis treatment must not be 

 attempted apart from that of the constitutional disorder with 

 which it is associated, and which in all these cases must 

 be regarded as the inducing factor of this bronchial dis- 

 turbance. While attending to the primary and general 

 disease, urgent bronchial symptoms must not be neglected, but 

 receive such attention as is calculated to relieve these special 

 developments. 



Complementary bronchitis, as associated with specific ar- 

 thritis in foals, I have found a very serious and intractable 

 extra development of symptoms. In these young animals, in 

 addition to the general or constitutional treatment adopted 

 for the systemic disease upon which this secondary bronchitis 

 depends, relief is always afforded by the local application of 

 hot, damp rugs or woollen cloths, followed by gentle friction 

 with compound soap and opium liniment, w^hile the exhibition 

 frequently of moderate doses of stimulants, combined with 

 salines, seems adapted to both this extra development of 

 symptoms and the original constitutional disease.
