(After Leuckart.) the body, thus setting up the second phase of the disease, known as muscular trichinosis. Trichinosis as a disease has long been recognised. Peacock in 1828 and J. Hilton in 1832 mentioned the existence of the cysts of trichinse; Owen in 1835 gave the name of Trichina sjyiralis to the parasites con- tained in the cysts. Trichinosis being common in Germany at that time, Virchow and Leuckart undertook its investigation, but mistook other nematodes of the intestine for the Trichina'spiralis. In 1847 Leydy recognised that trichinosis occurred in American pigs.
