The intimate relations in which domestic animals stand to man have always made the transfer of parasites from the one to the other a matter of much greater probability than exists between man and the other forms of animal life. It is but natural that the most common species of human tapeworm come to man from his two chief sources of animal food-beef and pork.

So far as natural science is concerned, the varied training which it affords has been abundantly discussed before this association and elsewhere. To be sure, …
