Savannah, Ga., April 20, 1899. To the Editor: —Referring to the editorial in theJournalof April 15 (p. 827), I think Flugge greatly exaggerates the danger of infection by means of the fine drops expelled from the mouths of phthisic persons in coughing. He hasnotby any means proved that tuberculosis iscommonlytransmitted by such drops. I believe the only danger, save in exceptional cases, of the open mouth coughing, is that such drops soon become dried and act as so much dried sputum. The danger of inhaling such drops under ordinary circumstances is slight. Cornet's recent works proved conclusively that tuberculosis may be disseminated by dried sputum dust. Very respectfully,
