DISEASES OF THE LUNGS. 153 



on the contrary, the characteristic results of acute disease. 

 Indeed, the darkly coloured friable condition of the lungs, 

 with the tendency to putrefaction and liquidity of the 

 pulmonary tissue, without the formation of organized exuda- 

 tion, so far from being the result of chronic disease, are in 

 all cases characteristic of acuteness of attack. 



Treatment. — In the treatment of acute congestion, it is 

 imperative that the horse have a plentiful supply of pure 

 fresh air, and strict quietude and repose should be enjoined 

 in all cases. The body should be well rubbed with wisps of 

 straw and afterwards warmly clad. The legs should be 

 carefully bandaged with thick wool or flannel, being pre 

 viously rubbed with some stimulating liniment. 



Internally, diff'usible stimulants, as ether or alcohol, in its 

 various forms, in moderate and frequently repeated doses, 

 are of great value in helping to restore the flagging circula- 

 tion. Acetate of ammonium, or nitrate of potash, may with 

 advantage be given in addition to the stimulant. 



Professor Williams speaks favourably of the tincture of 

 arnica ; but we have not found the efficacy of this medicine 

 much to be relied upon in this disease. 



If the symptoms are still unrelieved after this treatment, 

 bleeding is necessary, in order to relieve the pulmonary con- 

 gestion and~^ the engorgement of the great veins and right 

 side of the heart, and thus avert impending suff'ocation. 



From three to four quarts of blood may be withdrawn. 

 It is not advisable to repeat the bleeding, nor to apply 

 mustard or other irritants to the sides of the animal, as 

 these measures merely annoy the animal and thus increase 

 the respirations and enhance the dyspnoea. 



In order to guard against inflammation of the lungs, 

 which sometimes succeeds acute congestion, as well as to 

 prevent the recurrence of the congestion itself, careful 

 management is required for some time after the abatement
