Trichiniasis is not a mere medical curiosity; it is a common and important disease and one all too seldom recognized. A disease having an average mortality about half that of typhoid fever, and in some epidemics a mortality rising to 16 or even 30 per cent., as in the Hedersleben epidemic1 in 1865, is serious. Proof that it is a common disease may be had from studies such as that of Williams,2 who in 105 unselected necropsies in the state of New York found trichinella embryos in 5.4 per cent. In other civilized communities, this parasite is found in from 0.5 to 2 per cent, of necropsy subjects. About 6 per cent. of American swine, and a larger percentage of American rats are infected.
Recent years have added much to our knowledge of trichiniasis. The life history of the parasite and its methods of migration and distribution in
