...during the twenties to assess the value of this work. For, however much its editors have sought to make it an historical document, this photographic panorama of the United States since 1860 must, through its very character, remain an effort dedicated to the artful stimulation of nostalgia. Perhaps that virus, bolstered as it is by the camera and by Mr. Allen's informal chatter, will prove itself not yet exhausted by the thorough ministrations of Mr. Mark Sullivan and the self-styled humorous magazines. One is inclined to feel however that such a work is, now at least, better suited...
...National Academy of Sciences at Cambridge. Mass, last week (see p. 50) Dr. Simon Flexner, director of Manhattan's Rockefeller Institute for Medical Research, reported that Institute researchers confirmed the widely accepted theory that this pathway is traveled by one of mankind's deadliest enemies-the virus of infantile paralysis...
...pathway, explained Dr. Flexner. is the one by which the sensation of smell reaches the brain. Exposed in the mucous membrane of the nose lie the hairlike end-processes of the olfactory nerve cells. Up these nerves, which are relatively isolated from the blood and lymph, the attacking virus passes direct to the brain's olfactory lobe, thence proceeds to invade more distant parts of the brain and spinal cord. The invaders, injuring motor nerve cells, produce muscular paralysis. The damage done, some of the virus returns the way it came, goes out from the nose...
...School by the Harvard Infantile Paralysis Commission under the direction of Dr. W. Lloyd Aycock. However, although everyone has the disease, only an occasional child becomes crippled. The average person merely contracts a mild form, which is usually not recognized, and from it develops immunity, subsequent exposure to the virus producing no ill-effects...
...Since the nerve cells controlling muscles are destroyed by this affliction, it cannot be hoped that a cure will be found after those cells have become seriously infected. Instead, some way must be found by which the occasional susceptible person can be made to resist the virus. Immune serum has already been used for early treatment; but the difficulty of experimenting on children, and of finding comparable untreated cases, has been a serious drawback in this investigation. It is known, however, that because of the mildness of early symptoms in some children, the disease would not be recognized...
