 and German j^orts because the inspection was declared to be 

 unsatisfactory. We must be prepared to expect the same if 

 we do not profit by the lesson, and start the most rigid 

 inspection of all meat that leaves Australian ports. 



5.— SOME OF THE DISEASES OF ANIMALS COM- 

 MUNICABLE TO MAN, OR COMMON TO BOTH. 



Bii ARCHIBALD PARK, M.R.C.V.S. 



In drawing' attention to the necessity for more extensive 

 research in investigating* the above subject throughout the 

 Australian Colonies, the obscurity of some diseases or their 

 confusion with othei's has led to a great deal of misunder- 

 standing among professional men, and the probability that 

 legislation, at perhaps a date not far distant, may be asked 

 to deal with some of those diseases in a stringent manner 

 he^ove t\\e\v real OY assumed characters are carefully investi- 

 gated. The conditions in which many diseases exist in 

 Australia is entirely different from Europe or England, where 

 we take our cue from ; for example, tuberculosis does not 

 spread among cattle in Australia by had ventilation, as in 

 Eurojie, because our cattle are (millions of them) never 

 housed. Our poultry contract tuberculosis that show the 

 typical headed bacilli of the human subject. Turkeys seem 

 to be specially liable to this form. Their habits are of a 

 v/andering nature, yet they seem to contract this disease 

 without any trace of consumptive patients near their feeding 

 places. " Actinomycosis " has long been confounded with 

 cancer and tuberculosis, and although in many instances 

 attacking human beings, is derived from the same source as 

 cattle. Before the growth of the fungus can take place 

 some primary lesion must exist to form a nidus for develop- 

 ment of the organism. 



Coccidium Oviforme, 



A disease for the last thirty years confounded with tuber- 

 culosis, has within the last few years been found associated with 

 "cancer," and is due to the pi-esence of ovoid bodies belong- 

 ing to the " protozoa." These parasites live in marshy places 

 as well as in the animal body, and are especially numerous 

 in the hver of rabbits, Water drawn from a source con-
