fusion of the fluid from within the chest into the surrounding tissues. 

 The accumulation iu the chest is called hydro-thorax or dropsy of the 

 chest. When this fluid coutaius pus the case usually proves fatal. The 

 condition of pus within the cavity is called empyiema. 



Pleurisy may affect only a small area of one side, or it may alfect 

 both sides. It is oftener confined to the right side. 



Treatment. — This varies very little from the treatment of bronchitis 

 and pneumonia, but as frequently stated heretofore, pleurisy is so lia- 

 ble to be complicated with either of the diseases named, the variation 

 iu the treatment may be considered as merely adjunct treatment of the 

 pleuritic complication. 



The instructions in regard to the general management of bronchitis 

 and pneumonia must be adhered to in the treatment of pleurisy. Com- 

 fortable quarters, pure air, warm clothing to the body and bandages to 

 the legs, a plentiful supply of pure cold water, the laxative food, etc., 

 in this case are equally necessary and efficacious. The hot applica- 

 tions applied to the chest as directed in the teeatment of pneumonia 

 are very beneficial in pleuri-sy, and should be kept up while the symp- 

 toms show the animal to be in pain. 



During the first few days, wh«u pain is mamfes,ted by restlessness, 

 do not apply the liniment to the sides of the chest, as it will not only 

 irritate the animal and increase the restlessness but will heighten the 

 fever as well. After four or fiTe days, when the symptoms show that 

 the acute stage has somewhat subsided, the liniment may be well 

 rubbed over the affected part with benefit, as it will greatly promote 

 the absorption of the effusion. The application may be repeated on al- 

 ternate days until several applications have been made. From the be- 

 giuning the following drench should be given every six hours : Solu- 

 tion of the acetate of ammonia, 3 ounces ; spirits of nitrous ether, 1 

 ounce; bicarbonate of potassium, 3 drams; water, 1 pint. 



If the patient becomes debilitated the stimulants as prescribed ibr 

 pneumonia should be used according to the same directions. The same 

 attention should be given to the diet. If the animal will partake of 

 the bran mashes, scalded oats, and grass, it is the best, but if he re- 

 fuses the laxative diet then he should be tried with different kinds of 

 food, and allowed whichever kind he desires. 



In the beginning of the attack, if the pain is severe, causing the ani- 

 mal to lie down or paw, the following drench should be given: Tinct- 

 ure of opium, 2 ounces; raw linseed oil, 12 ounces. If the pain con- 

 tinues, the tincture of opium may be repeated within four or five hours. 



If the case is not i^rogressing favorably in ten or twelve days after 

 the beginning of the attack, convalescence is delayed by the fluid iu the 

 chest failiug to be absorbed. The animal becomes dull and weak, and 

 evinces little or no desire for food. The breathing becomes still more 

 rapid and difiicult. An effort must now be made to excite the absorp- 

 tion of the effusion. An application of the liniment should be rubbed 

 over the lower part of both sides and the bottom of the chest. The
