broke out among the horses which had been feeding upon the 

 same grass and drinking the same water as the beasts. One 

 horse died within three hours, and three others which were 

 aifected made a slow but perfect recovery. On another occasion 

 — namely, in February 1878, out of a herd of fifty beasts to 

 which Mr. D. Gresswell was summoned only two survived. These 

 animals had been fed upon decomposing grains. 



In SHEEP the anthrax germ usually invades the intestinal 

 tract, the splenic form of the disease, in which the spleen is espe- 

 cially attacked, being much less commonly met with than is the 

 case on the Continent, where this kind is the one which generally

The above picture represents a lamb afflicted with navel-ill. The navel is 

 seen to be greatly swollen so as to be larger than is natural. The poor little 

 creature's tongue is seen to be protruding, and, indeed, our artist has faithfully 

 delineated a certain look of helplessness and bewilderment which, in the case of 

 a living animal, would incite the observer to search out among the resources of 

 science for some remedy wherewith if possible to remove the cause of the 

 suffering.

 cially are affected, the sheep at first walk with contracted step, 

 owing to the abdominal pain. Soon they stand with dejected 

 look, arched back, and then they fall to the ground, and the 

 belly may be noticed to be swollen and tender. After a time the 

 wool drops off. If, on the other hand, the disease especially 

 affects the spleen, the symptoms manifested are very similar to 

 those met with in oxen suffering from the same disease. In 

 lambs, however, this form of the disease is often characterised 

 by external swellings oftentimes involving the navel. In the 

 latter case it is spoken of as '* navel-ill." 



The symptoms are briefly as follows : — The sheep or other
