AND ITS RELATION TO ANIMAL LIFE 83 

 SOUTH AFRICAN HORSE-SICKNESS. 



" The newly formed South African Associa- 

 tion for the Advancement of Science met in 

 Capetown yesterday. Dr. Edington delivered 

 a lecture on animal diseases, in which he showed 

 that the material form of horse-sickness, with 

 parasites in the blood, and several other stock 

 diseases which have not hitherto been defined, 

 are the same malady existing in relative viru- 

 lence for particular species." Renter. 



If this be admitted, it would seem that the 

 most practical way of coping with this disease 

 would be to attempt to restore this deficiency 

 to the veldt, and from a financial point of view 

 any reasonable expenditure would be thoroughly 

 justified, seeing the large expanse of otherwise 

 valuable land which is to-day yielding practic- 

 ally no revenue. 



As to how the disease spreads there is 

 nothing absolutely definite, but there is no doubt 

 that animals dying and decaying on a given 

 veldt do cause some pastures to become in- 

 fected ; but this does not always apply, for 

 there are many cases where sheep dying of the 

 disease have been placed on healthy country
