 the peritoneum, he discovered the appearances of endocarditis, 

 that he had produced the characteristic lesion of rheumatism. 

 Endocarditis is a very acute and dangerous disease. It is, 

 perhaps, more dangerous from the results to be feared than 

 from its tendency to kill in its acute stage, though this is not 

 an unfrequent occurrence. 



The causes of endocarditis are very similar to those of peri- 

 carditis, and must often be grouped with those of rheumatism. 

 A constitutional tendency appears in animals as in man to 

 influence the production of this disease.

 rheumatic fever are attended with very marked local symp- 

 toms of heart disease. There is very decided interference 

 with the action of the heart, and its contractions are energetic,
