222 ON THE OCCURRENCE OF " WORM-NODULES " IN CATTLE 



the Australian parasite, 0. Gihsoni, prefers the brisket 

 and flank. 



The work of these French parasitologists was not 

 available until after the publication of our official report 

 on " Worm- Nests (Filariasis) in Cattle " (Cleland and 

 Johnston, 1910, c). In this article, we reviewed the Australian 

 literature and the public health and pathological aspe;cts 

 of the condition. We also gave a more detailed account 

 of the ana,tomy of the worm and of its relationship to 

 various other species of Onchocerca, such as 0. volvulus,. 

 which causes nodules in man in certain parts of Africa 

 (Fiilleborn, Rodenwaldt, Parsons, etc.), and 0. reticulata,. 

 which gives rise to a similar condition in horses (Pader). 

 An account of experiments to determine the mode of 

 transmission was also given. An allied parasite infest- 

 ing the camel was dealt with incidentally, and was 

 thought to be perhaps identical with 0. gihsoni. The 

 camel parasite is, however, a distinct species (0. fasciata), 

 as Railliet and Henry (1910) have shown. Some of the ground 

 traversed by these authors was also covered by ourselves. 

 Their paper reached us in time to allow us to add a reference 

 to it as an addendum to the above article in its rearranged 

 condition, when it was published in the form of two papers 

 (1910, cZ, 1910, e), bythe Royal Society of New South Wales. 



Early in the present year (1911), a number of papers 

 appeared, the most important being one by Leiper (1911, a), 

 an article by Macfadden (1911) accompanying it. Others 

 were published, or rather republished, by the editor of 

 the Journal of Meat and Milk Hygiene (Jan. 1911, p. 21-26), 

 while the February number of the same journal contains 

 a brief article by NicoU (1911). 



Macfadden (1911) gave an account of the official 

 method of inspecting the carcases in London, the present 

 inspection being much more detailed and thorough than 

 that detailed by Hancock (1910), as being in force a short 

 time before. He referred to the heavy infection occurring 

 in some shipments, and to the difficulty of coping with 

 large consignments of Australian beef arriving at the port 

 of London. 



Leiper's paper (1911, a) is a valuable one. In it he 

 deals mainly with the anatomy, geographical distribution, 

 and pathological effects of the parasite. In addition he
