TRANSMISSION OF DISEASES
PART PLAYED BY NERVES OF SMELL AMERICAN DISCOVERY (Received November 22, 7.5 p.m.) CAMBRIDGE (Massachusetts), November 21. The discovery that the sense of smell is the avenue through which some of the most baffling epidemics spread was announced by Dr. Simon Flexner, who reported on experiments showing that the virus causing infantile paralysis enters the brains of monkeys by travelling from their noses through the olfactory nerves. Not only did the virus enter by the nerves associated with the sense of smell, but those nerves formed "two-way transport." The virus could pass from the paralysisinfected brain, down the olfactory nerves and out through the nose. The insidious nature of the attack through the olfactory nerves was shown by monkeys immunised so that they did not get paralysis when the virus was injected directly into their brains, yet the disease attacked them when the virus was allowed to enter their noses.
