Cause and source of infection are now settled beyond a doubt to be from the eggs of the Taenia Solium of man, which is eaten by the pig. It has been as conclusively shown that the tapeworm (Taenia Solium) of man comes from further development of the measle in the pig. This tapeworm found in man is a long, flat worm like a tape-measure, and is made up of joints or segments. Kach segment of the worm bears male and fe- male organs of generation, and each scg- Measle8 or c?sticercus ln Pork« ment is also loaded with thousands of fertile eggs. These egg- bearing joints become detached from the body of the worm and pass off, new joints are formed and the process is repeated as time goes on, and any number of the segments so detached will not destroy the worm so long as the head remains. The eggs con- tained in the joints are liberated and no amount of freezing or drying will destroy their vitality. Some of the innumerable quantity of eggs thus deposited findtheir way into the digestive canal of the pig through the manure pit, contaminated pools, or grass to which the ova may adhere, etc. The egg is there hatched and the worm liberated to burrow through the tissue and lodge in the muscles. The habit, in rural districts, of depositing human excrement upon the surface of the ground or in the manure pit, to which the pigs have access, renders it possible for one person having a tape-worm to infect in this way a whole herd of swine; and again, one of the infested herd may, when slaughtered and eaten, infect nearly all who partake of its flesh, unless the parasite is destroyed by cooking. Prevention is much more to be relied upon, as will be seen from the foregoing article, than treatment. The history and manner of transmission of the disease as given above will aid in adopting such plans as will prevent infection. The common custom in many di
