PROCEEDINGS OF SECTION I. 687 



in the upper air passages, siicli as the pharynx, whence they would 

 easily reach the various lymphatic glands of the neck. Cattle, we 

 know, rest together at night time, and frequently lick each other, and 

 either of these processes would give ample opportunities to diseased 

 cattle to distribute tubercle bacilli amongst their fellows. 



In pigs the glands of the neck bear by far the chief incidence of 

 the disease. In them, I think, it is probably due to the feeding on 

 improperly cooked tubercular milk or meat, the bacilli gaining entrance 

 through the numerous membranes. The remedy is obvious. 



The Prevention of Extension or Tuberculosis in Cattle. 



I am afraid I can suggest but little of practical import here. It is 

 imperative, however, that something should be done, and I should like 

 strongly to urge that the Federal Government should appoint a com- 

 mission to investigate the matter, and devise remedies. Otherwise, 

 it will be again the cry, " Too late ! too late ! " Stockowners might 

 be induced to destroy all obviously diseased animals and burn their 

 carcasses, and to segregate the calves from the rest of the herd, while 

 infected districts might be sharply marked off and quarantined from 

 non-infected. 



(2) ACTINOMYCOSIS. 



Actinomycosis, caused by the ray-fungus, and most typically 

 known in the condition called " lumpy jaw," is not very rare in north- 

 western cattle. Twenty-seven cases in cattle have been met with in 

 various parts of the body in three and a half months. The fungus is 

 probably introduced attached to grass seeds. It is rarely, if ever, 

 conveyed directly from animals to man. 



(3) OTHER INFECTIOUS DISEASES. 



Anthrax may possibly exist in the State, but has not yet been 

 reported as such. 



Foot and mouth disease, trichinosis and measles {cystidercus 

 cellulozcp) in pigs, and measles in cattle (C. hovis), are so far not known. 



DISEASES INDIRECTLY COMMUNICABLE TO MAN. 



Hydatids. — This disease, conveyed to man, cattle, sheep, and pigs 

 through the intermediation of the dog, is of fairly common occurrence 

 throughout the State. To prevent its spread the viscera of all animals 

 slaughtered and containing hydatid cysts should be rendered sterile 

 before giving the offal to dogs. Dogs are forbidden within the precincts 

 of our abattoirs. 



Insfertion. — As to this, there is no direct danger to man. When the 

 cysts in the liver are few or small, the affected portions are removed 

 and destroyed and the rest passed. If the invasion is extensive, the part 

 is condemned.
