aconite 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 or two doses will be all that is required to 

 effect a cure. 



(2.) Pleurisy. — Inflammation of the membrane covering 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, accom- 

 panied with a sigh or grunt. A peculiar line will 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 inflam- 

 mation of the lungs. In the first twenty-four hours after the at- 

 tack, pain will have given way, 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 Hydrothorax (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. Bro- 

 ken ribs or wounds. 



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 termination 

 of the inflammation of the lungs. Pus is a common result of in- 

 flammatory action, and when in the lungs is called vomicae, causing, 

 in some cases, consumption. Where absorption of the pus has 

 taken place, glanders is the result. 



The abscess frequently breaks into the bronchial tubes, and then 

 pus escapes into the larynx and nares of the nose. Plence the per- 

 sistent discharge which is so characteristic of glanders. 



Treatment. The same as for glanders ; generous diet, tonics, and 

 stimulants, with the sulphite of soda and the Spanish fly. (See 

 Glanders.) 



(4.) Effusion of Serum. — Kydrothorax is one of the ways in 

 which pleurisy terminates, and when this effusion is extensive^
