CHRONIC VAIvVUIvAR DISEASE OF THE HEART. 



This, as already noticed, is a common result of endocarditis, 

 the valves being most obnoxious to disease in such cases. The 

 symptoms are those mentioned under endocarditis as character- 

 izing disease of the different valves, such as incapacity for exer- 

 tion, difficult breathing, palpitation, irregularity or intermission 

 of pulse, venous pulse, abnormal heart sounds, unsteadiness of 

 the limbs when driven, and dropsical swellings in the limbs and 

 elsewhere. The reader is referred to endocarditis for particulars, 

 it being borne in mind that these symptoms are not in this case 

 associated with fever. 



Horses affected in this way are useless. Cattle may sometimes 

 be partially fattened by preserving them from all sources of ex- 

 citement, by keeping the bowels regular and by combating any 

 paroxysms with sedatives, such as aconite, veratrum, hydrocyanic 

 acid, or opium, and with digitalis.
