Since the completion of this investigation an article has appeared in the Archiv für Klinische Chirurgie, by Mendes de Leon, describing experiments conducted along the same lines as my own, and having practically the same results. Dr. de Leon calls attention to the work done in Flügge's laboratory which proved the importance of droplets of sputum in the dissemination of tuberculous infection, and comments on the fact that the sputum as a source of infection has apparently been overlooked by surgeons.

During an ordinary operation, not performed before a class, a surgeon speaks from 150 to 500 words. Plates laid on the table before a number of surgeons while
