DEOPSY OF THE CHEST. 



^ This is a collection of serum, or water, in some of the cavi- 

 ties of the chest. The quantity of water may be very great. 

 It is always fatal. The scientific name of the disease is hjdro- 

 thorax. 



Symptoms. ~T\\cvQ is considerable excitement of the system, 

 the pulse increased in fi-equency, the breathing very laborious' 

 the feet and legs cold, and there is some puffiness or water 

 under the skin, about the chest and breast; the gait is awkward 

 and straddling with the fore-feet. The animal loses flesh very 

 fast, and looks haggard; strength rapidly fails, and the ani- 

 mal refuses to lie down until death takes place. 



Causes.~T\\Q most common causes of dropsy of the chest are 

 badly-treated pleurisy, pneumonia, etc. Any thing which re- 

 duces very much the red part of the blood may cause it. 



Treatment— AW experience would seem to show that this dis- 

 ease is out of the reach of medicine. I believe one result has 

 attended every plan yet suggested, and that is death. Tap- 

 pmg has been tried, but with no good results. I have nothing 

 to offer. The disease will soon pass to its termination.

 IS driven out of the lungs, is generally known by the name 

 of heaves, hroTcen-imnd, or thick-wind. It very much resembles 

 asthma in the human patient; but that disease only occurs in 

 paroxysms, or spells, whereas heaves is constant, especially 

 when the horse is exercising. 



Sfjmptoms.—TliQ peculiar" violent, heaving action of the ribs 

 and flanks, m forcing the air from the lungs, is sufiicient evi- 

 dence of the existence of the disease. By observing the
