According to Dr. R. E. Drake-Brockman the transmitting agent 

 in Somaliland is OrnitJwdorus savignyi, and although Argas persicus is 

 abundant, there is no proof of its being capable of becoming the vector. 



Dr. H. M. Woodcock has found a distinct difference in the number 

 of spirochaetes in the louse-borne and tick-borne cases of relapsing 

 fever and he considers it quite possible that Argas may be the trans- 

 mitting agent. According to Dr. A. Balfour, although this is not 

 impossible, further proof is required before the hypothesis can be 

 accepted as a fact.

The bulk of the information here given has been noticed elsewhere 



[R.A.E., B, vi, 225 ; viii, 10]. Recent investigations confirm previous 



statements [loc. cit.], but it has been found that the blood of patients 



mav remain infective and be capable of infecting lice fed on it as late 



as the 443rd day of the disease.

The anti-malarial work carried out by the Australian forces in the 

 vicinity of the river Aujah, including the usual treatment of breeding 

 areas and prophylactic measures, are described. Although all possible 

 precautions were taken nearly 2 per cent, of the men contracted 

 malaria, but the majority of these were probably infected by 

 mosquitos deriving their origin in enemy country. 



With the return of these malaria carriers to Australia the necessity 

 of early investigations and treatment of both primary and secondary 

 cases is emphasised. Should many fresh cases occur, complete eradica- 

 tion of the anophehne breeding areas will have to be undertaken.

 Only isolated cases of demodectic mange have been met with in the 

 Zomba and Blantyre districts, but in Southern and Northern Rhodesia 

 the disease is still giving great trouble. W^ith the co-operation of 

 planters and systematic dipping against ticks it is hoped that piro- 

 plasmosis in cattle will entirely disappear. Investigations are being 

 made in connection with a new disease of calves and sheep of which the 

 causal organism resembles a piroplasm. 



Isolated outbreaks of trypanosomiasis have been reported from all 

 parts of the Shire Highlands. In the Mlanje district the disease is 

 spreading and it is feared that Glossina brevipalpis is more widely 

 distributed than was previously thought to be the case.
