VETKUIXAUY NOTKS 



One may conchidu liy iiotiiif,' tliat on botli occasions when the l)looil was found to 

 contain tlie parasites the examination was made about mid-day, and that gerbils, a jerboa 

 and a younj; rabbit inocuhvted with blood from the pony, in connection witli work on 

 the trypanosome. have failed to exhibit the tilaria. 



In the Camei, 



In an article on Debab, the camel trypanosomiasis of Algeria, the Sergents' mention 

 the frequent presence of micro-tilaria; in the blood of camels but they do not describe them. 

 Mason- has found these parasites in the peripheral blood of camels in Egypt. He 

 does not describe them either, but mentions their apparent periodicity, as they were 

 more easily found in smears taken late in the afternoon or at night. He also mentions 

 the discovery in the testicle of camels of what may be the parent worms. What he took to 

 be a female was 20 cm. long, while the males were 12 cm. in length and possessed 

 tails curved in a spiral manner. These worms were found in a bunch in the central 

 vein of the organ. In the Report of the Government Bureau of Microbiology of New 

 South Wales for 1909, an account is given of filaria embryos found in the blood of camels 

 in Western Australia. They appear to have been the embryos of the Indian F. evausL 

 A Sudan case In March, 1910, I found micro-filariae in films of camel's blood sent me bj' 



Mr. E. T. von Becker, of the Sudan Customs Department, from Korara, in the Red Sea 

 Province. Being a microscopist, Mr. von Becker liad himself noted the presence of worm- 

 like bodies in the films but was not able to diagnose them, though he was well up in 

 trypanosome infections. 



Sijmptoms. —According to Mr. von Becker these are quite unlike those seen in camels 

 suffering from trypanosomiasis and are as follows : — 



1. Loss of appetite. 



2. Roughened and staring coat. 



3. Watery secretion from the eyes. 



4. oedema of the extei-nal genitals. 



At the time the sick animal w^as examined it had been ill for 9 months. It was stated 

 that there had been temporary improvements but latterly a rapid decline, the camel being 

 very weak and emaciated. 

 Morphology of The parasite. — No opportunity was afi"orded me of studying this niicro-filaria of 



the parasite ^j^^ camel in the living state, but Mr. von Becker describes its movements as rapid and 

 snake-like. Fig. 1 on Plate XVII. gives a good idea of it in stained preparations, though, as 

 a rule, the food material, so clearly shown, is not quite so much in evidence albeit constantly 

 present in all specimens examined. There was about one parasite per film. The length 

 varies from 220/i to 237^ and it will be seen that the cylindrical body shows definite clear 

 areas or spots. In a parasite measuring 220/i the positions and sizes of these areas were as 

 follows : — ^One, at the cephalic extremity, 10^ in length and occupying the whole breadth 

 of the body, a second, with irregular margins, -45/1 from the cephalic end and running 

 obliquely across the whole body thickness ; a third, roughly oval in shape, 65^ from the 

 anterior extremity and taking up three-quarters or the whole of the body breadth ; a 

 fourth, of irregular shape, stretching nearly wholly across the parasite and some 30fi from 

 the sharp tail tip.
