PLEURISY 51 



If pressure on the sides is applied, the horse will feel 

 pain, and express it by a quick and impatient grunt. 

 The unwillingness of the horse to lie down will -be 

 manifested in this as well as in violent inflammation 

 of the lungs. 



CAUSE. This disease has its origin from the same 

 causes as inflammation of the lungs, viz., sudden 

 transitions from heat to cold, etc. 



REMEDIES. Much the same treatment is required 

 for pleurisy as for pneumonia. The two diseases are 

 frequently conjoined, and a veterinary surgeon can 

 alone decide this point. 



If pleurisy is acute, it frequently induces dropsy 

 in the chest, as in this complaint a fluid is thrown out 

 from the vessels of the pleura, which, having no 

 means of escaping, and being too large in quantity 

 to be absorbed, lodges in the cavity of the chest. 

 When this is the case little good is to be expected 

 from the animal, and it seldom happens that a com- 

 plete cure is effected. Sometimes the chest is punc- 

 tured for it, which may carry off the fluid ; but it 

 too frequently proves an ineffectual remedy. When- 

 ever it is suspected that water is formed to any great 

 extent, puncturing should be had recourse to, the 

 opening to be made by the instrument called 

 the trochar. The locality where it is inserted is the 

 intercostal membrane, between the seventh and 

 eighth ribs, and as close to the cartilages as possible. 

 Diuretic medicines, in combination with tonics, should 

 be given. The following will be found the best : 



Nitrate of potash ... ounce, 

 Ginger ..... J drachm, 

 Linseed meal J ounce ; 



made into a ball with common syrup or treacle.
