CATTLE MALARIA 305 



blood during its continuance. They consider the bodies 

 to be endocorpuscular parasites. 



A rapid and certain diagnosis can, however, be made by 

 the examination of the blood, whereby cases can also be 

 detected which would otherwise escape observation. The 

 disease appears to be identical with that described by 

 Babes in Roumania as cattle haemoglobinuria ; by Smith 

 and others as Texas fever ; and by Sanfelice and Loi in 

 Sardinia as hsmatinuria. When one considers the above- 

 mentioned clinical characters, together with the character- 

 istics of the parasite, the post-mortem appearances, the 

 communicability from one animal to another of the same 

 kind and race, and the further circumstances that the 

 disease develops only in malarial neighbourhoods and 

 seasons, and is most favourably influenced by quinine, its 

 resemblance to human malaria is seen to be very marked. 



Rinderpest. 



This disease, which has recently caused such havoc 

 amongst cattle in India and South Africa, has recently 

 been investigated by Dr. Simpson, who has given the 

 following particulars concerning it before a recent meeting 

 of the Calcutta Microscopical Society. 



The microbe is a diplobacillus, varying from 0-3 to 

 0-6 mm. in length, and about a third of this in breadth. 

 Occasionally two diplobacteria are fixed end to end, and 

 give the impression of a longer bacillus. The microbe is 

 not unlike the bacillus found by Dr. Klein in ordinary 

 calf vaccine. It is easily stained by the ordinary dyes, 

 fuchsine and gentian violet. It grows aerobically and 

 anaerobically, but gradually becomes attenuated in virulence 

 by repeated growth in air, so much so that in the early 

 part of ] 895 two tubes rubbed into sores on the skin of 

 an animal would kill the animal, whereas twelve tubes
