President Conant proposes non-credit American History study to "inoculate student body with educational virus...
...flowering as a Johns Hopkins pediatrician when the War broke out. As a first lieutenant in the Army Medical Corps he saw so much of the influenza epidemic of 1918 that after the Armistice he became a bacteriologist and the nation's foremost authority on the submicroscopic, filterable viruses which cause diseases like influenza. His great achievement, accomplished at the Rockefeller Institute, was to grow viruses in tissue cultures. This permits quantity production of unadulterated virus, so far chiefly useful for further research. Dr. Rivers latest work has been on a new disease, lymphocytic choriomeningitis, which attacks the spinal...
...years ago Dr. Wendell Meredith Stanley of the Rockefeller Institute built a sensational bridge between the living and the nonliving by crystallizing the virus which causes tobacco mosaic disease. Crystallization is a property of nonliving matter but when the virus was applied to the leaf it promptly acquired the ability to reproduce itself-a characteristic of life. The virus is a giant molecule weighing 17,000,000 times as much as a hydrogen atom. Dr. Stanley found the molecule to be spherical, with a diameter of .0000002 cm. When Dr. Langmuir made a monofilm of the virus and then transferred...
...virus molecule's diameter is just under the visibility limit of the most powerful microscopes. Dr. Langmuir made a molecule that anyone could see with the naked eye by adding acetic acid to a dilute solution of sodium silicate. After a while the solution became viscous and turned into a jelly. The molecules had combined to form bigger ones, the process speeding along in geometrical ratio until one super-giant molecule filled the entire container...
...plan was recommended to the Board of Overseers by President Conant in his recent report in which he expressed a desire to "inoculate the student body with an educational virus." He said that, "the importance of a knowledge of American History to every citizen is evident...
