Abstract

THERE has been considerable speculation recently upon the cause of the so-called “virus diseases,” which occur in both animals and plants, such as typhus and Rocky Mountain fever in man, and “mosaic” disease in plants. These diseases are supposed to be due to the presence of some ultramicroscopic filter-passing organism. Many small bodies, some of a granular nature, have been described in connexion with these disorders, such as Rickettsia, Negri bodies, etc. As regards the mosaic disease of plants, L. O. Kunkel, a worker in Hawaii, last year demonstrated the presence of a peculiar body of amceboid appearance in the diseased cells of maize affected with mosaic.
