THE BACTEEIA IN CONTAGIOUS MALADIES. 173 



exist between the bacteria of ' glanders and of 

 charbon, we recall the fact that Bedoin, having 

 mixed some powdered borax (two grammes) with 

 the blood of a glandered horse, has found the 

 bacteria completely motionless at the end of two 

 hours. These results correspond with those which 

 Decroix, veterinarian of the army, has obtained 

 by treating horses attacked with charbon with 

 boracic acid. 



Ulcerative Endocarditis. — In this affection, it is 

 well settled to-day that the cardiac walls and, 

 above all, the valves are covered with parasitic 

 masses. Some think that the malady is due to the 

 introduction of these parasites into the interior 

 of the tissues ; others, on the contrary, like Hiller, 

 deny that the bacteria bear any causal relation 

 with the lesions of ulcerative endocarditis. Ger- 

 ber and Birsch-Hirschfeld have recently made an 

 observation which is a complete refutation of the 

 ideas supported by Hiller. They have found at 

 the autopsy some hemorrhagic foci disseminated 

 in various organs, the greater number of which 

 contained some particular corpuscles belonging to 

 the class of the bacteria. 



Belapsing Fever. — In 1868, Otto Obermeier 

 discovered in the blood of the sick attacked with 

 recurrent fever certain bacteria, called by Cohn 

 Spirochete Obermeieri. These organisms are only 

 found during the febrile paroxysm ; after the ac- 

 cess of fever they disappear, but often they are
