 July 1920, pp. 535-539. 



The author does not consider the identity of OncJiocerca volvulus 

 with the organism producing filarial mange, discussed in a preceding 

 paper [R.A.E., B, viii, 183], to be by any means proved, and he 

 gives an account of the filarial form of dermatitis which is very 

 widespread in Africa in regions where 0. volvulus does not occur. He 

 points out that if the identity were established, it should be possible 

 to demonstrate that all persons suffering from this form of mange 

 harbour adults of 0. volvulus, and that all individuals with tumours 

 due to 0. vohulus show the eruption produced by the microfilaria. 

 Many biological facts are quoted that throw doubt on the role of 

 0. volvulus in filarial mange, and hoped it is that this point may shortly 

 be elucidated,

In furtherance of the tests with wood-tar obtained from Jukvperus 

 ■phoenicea and Thuya articulata as a cure for mange in camels [i?.^J^ 1 A i*^ 

 B, vii, 85 ; viii, 81] treatments were given to 11 camels sufliering from " 

 mange that were intended to be used for laboratory expeHEBgnts ,, 



in the Pasteur Institute at Algiers and were necessarily kept under '''^ Mviao\; 

 somewhat unhealthy conditions. Besides the wood-tar, treatments 

 were given with 1 part carbon bisulphide dissolved in 3 parts of 

 petroleum, the whole body of the animal being treated 3 times at 3 

 day intervals. The conclusion was reached that under the particular 

 conditions of life to which these animals w^ere subjected, wood-tar 

 is inefficacious in curing mange, and at the most may serve to keep 

 the animals alive. While carbon bisulphide and petroleum form a 

 better antipsoroptic, they are not a radical cure.

It was discovered many years ago that the epizootics known as 

 " peste boba " and " desrengadera," which cause a high death rate 

 among equines in Venezuela, are due to a trypanosome. The species 

 implicated was at first thought to be Trypanosoma equinum, the 

 causative agent of mal de caderas. Later F. Mesnil demonstrated that 

 the Venezuelan flagellate is morphologically distinct from T. equinum, 

 and while recognising its resemblance to T. evansi, the cause of surra, 

 he described it as a new species, T. venezuelense. About the same time, 

 T. hippicum, the causal agent of " murrina " in Panama, was described. 



The study of trypanosomiasis among Venezuelan equines has been 

 continued and the disease has been inoculated into various animals, 

 including the guinea-pig, rat, grey mouse, horse, opossum, monkey 

 and cattle. As a result of these investigations a good deal of fresh, 

 information is given on the morphology of T. venezuelense, its patho- 

 genic power, its resistance to drugs, etc. The facts recorded and the
