    In) The Ci/sticercus cellulosce of the pig produces Tcenia solium, and that of the ox and cow the Tcenia mediocandlata. These entozoa often arise from eatin the raw meat, but neither cooking nor salting are quite preservative, though they may lessen the danger. Smoking appears to kill the Cysticerci, and so accLling to Delpech, does a temperature of 212° Fahr. T Lewis* found that a much lower temperature sufficed. When the Cysticerci had been exposed for five minutes to a heat of 130 Fahr he could ments, and he considers that a temperature of from 135 to 140 for fie minutes would certainly kill them. Lewis considers there is no danger if the Toking TweU done, as the temperature of well done meat is never below 16 (o) The Trichina spiralis in the pig gives rise to the curious Trichina disease caused by the wanderings of the young Trichinae. The affection is highly feSe resembling typhoid or even typhus, or acute tuberculosis but attended ^KS^SiiH the limbs, and oedema.! Boils are also sometimes cluse!Tke eating of raw trichiniferous pork is the chief cause, and the eXzoon is not easily killed by cooking or salting.. A temperature of 144 to 155rFahr kdls the free Trichinae, but the encapsuled Trichm* may demand a later heaUFiecUer). During cooking, a temperatiire wmch will coagukte Snnen (U0° to 155° Fahr.) renders the TrichmaB incapable of proba- tion or destroys them. As a practical rule, it may be said that if the interior o a'pue ceofboded or roasted^ stains much of %^f-^^^ uncooked meat, the temperature has not been higher than 131 *^-> ff thereisstSdanger. Intense cold and complete decomposition of the meat do not dStwtt Irichina, Hot smoking, when thoroughly^ done does desteoy them (Leuckart); but the common kinds of smoking, when the heat is often W rlo not touch the Trichinae (Kiichenmeister).
