A TREATISE ON ELEPHANTS. 
(4) March the animals at night through country known to be 
infested with flies. 
(5) Isolate sick animals and protect them from the bites of 
flies.

Note. — Surra has been described at some length. Further information on 
this disease is solicited. As much light can be thrown on the subject I appeal to 
those gentlemen in charge of large numbers of elephants in the districts to keep 
a sharp look-out on all cases of fever, especially if accompanied by debility^ 
swellings, or both. Careful daily observation of the temperature will prove of 
assistance in suspicious cases, and 1 shall be pleased to receive early information 
of any outbreak of intermittent or remittent fever amongst elephants {see 
Appendix H).
