THE TAPEWORM LAR\ .E 215 



is harbored by the dog, rarely the cat, infection of man and domestic 

 animals is by the dissemination of the eggs of this tapeworm with the 

 excrement of its hosts. It follows that all hydatic viscera in slaughter- 

 ing establishments or elsewhere should at once be destroyed bv burning, 

 thus preventing the larval tapeworm heads from reaching the intestines 

 of dogs and cats. Where the disease has appeared it is a good precau- 

 tionary measure, though often impractical, to administer tceniafuge 

 treatment (p. 186) at repeated intervals to all dogs in the vicinity. 

 During the treatment the animals should be confinetl where their feca! 

 material can be caiefully collected and burned.
