Contagious Pleuro- Pneumonia of the Ox. 



463 



the experiments which were performed at the Royal Veterinary 

 College by Assistant Professor Axe, a few months ago, show that 

 inoculation with blood containing bacteridia is fatal to rabbits, 

 guinea-pigs, and goats in a few days, the blood of the inoculated 

 animals quickly becoming loaded with the same organisms.

What is the precise signification of these bodies has not yet been 

 determined ; but it has been observed that their existence in 

 the exudate from a diseased lung does not intensify the effects 

 produced by that fluid on an inoculated part. 



The exudate which occurs, in large amount, in the cavity of 

 the chest, in advanced cases of the disease, contains the same 

 elements as that from the diseased lung. 



In the next illustration (Fig. 2, p. 464) the germinal matter is 

 more abundant thanit is in the figure No. 1, otherwise the appear- 

 ances are identical. 



In this case a large quantity of germinal matter was also found 

 in the exudate from the diseased lunirs.
