root, in a cupful of cold water, and drench the horse. 

 Repeat the dose every four hours, till six doses are given. 

 In the majority of cases, one to two doses will be all that 

 is required to effect a cure. 



(2.) Pleurisy. — Inflammation of the membrane cover- 

 ing the lungs and lining the cavity of the chest. 



Symptoms. A rigor or chill, fever, disinclination to turn 

 short, an occasional short painful cough, and careful 

 breathing, accompanied with a sigh or grunt. A peculiar 

 line Avill be observed in pleurisy, running from the haunch, 

 round the belly to the breast-bone. The breathing is deep, 

 not so short and quick as in inflammation of the lungs. 

 In the first twenty-four hours after the attack, pain will 

 have given Avay, and the horse be apparently better. This, 

 in the majority of cases of pleurisy, when left a few hours 

 to itself and not checked, terminates in HydrothoraXy 

 (which see,) or water or serum in the chest, sometimes 

 causing adhesions. The favorable termination of pleurisy 

 is by what is called resolution. 



Causes. Changes in the atmosphere. Exposure to cold. 

 Broken ribs or Avounds. 



Treatment. Treat the horse as for inflammation of the 

 lungs, by giving him pure air, cold water and aconite ; 

 followed on the second day by five grains of powdered 

 Spanish fly in gruel, once in the twenty-four hours. To 

 remove the fluids from the body^ give, after the active stage 

 of the disease has passed, good feeding and generous diet. 



(3.) Abscess. — As elsewhere stated, abscess is the termi- 

 nation of inflammation of the lungs. Pus is a common 

 result of inflammatory action, and when in the lungs is 

 called vomica;, causing, in some cases, consumption. Where 

 absorption of the pus has taken place, glanders is the result. 



The abscess frequently brealis into tlie bronchial tubes.
