 disease." 1 



Though the worms have been well-known for so many 

 years and have been continuously under the scrutiny of 

 health and slaughtering authorities, who appear to have

 reference to them appears until one of us in 1907 recorded 

 their presence in cattle in West Australia. 2 This absence 

 of any references may no doubt be interpreted as indicating 

 that the disease plays little part in depreciating the value 

 of the animal or of its meat. 



In 1908-9, Mr. 0. J. Pound in Brisbane, reported having 

 received such nodules for examination, and in the latter 

 year one of us" mentioned their occurrence in New South 

 Wales cattle. Recently, however, the daily press has 

 recorded that the presence of these nodules in Queensland 

 meat in cold storage has been the subject of some concern 

 to the authorities in London. As the parasite appears to 

 be unknown outside of Austi alia, the nodules have in con- 

 sequence been viewed with some unwarranted suspicion 

 by the health authorities there. 



The last published papers on the subject as far as we are 

 aware, are one by ourselves describing shortly the parasite
