Previously designated as the Commission on Cross Infections in Hospitals.
Much of the unpublished work of the commission is referred to in various parts of the paper. These observations will be reported later in full by the various members of the group.
Jennison's 4 stroboscopic photographs show that the relative numbers of droplets produced by these activities is in the order named. Sneezing is by far the most productive of aerial contamination. Most of the droplets, however, leave by way of the mouth.

This is a modification of an emulsion described by the Carbide and Carbon Chemicals Corporation.
While this emulsion has been the one principally used in our study and many thousands of bedclothes have been treated by this means with satisfactory results, we have found that certain difficulties may be encountered in its routine use in laundry procedures. For this reason we are testing other emulsions which give promise of eliminating these difficulties. Details of this subject, together with an account of the laundry procedures involved in oiling bedclothes, will be published.
Dr. Lyman J. Briggs, director of the National Bureau of Standards, and Mr. S. H. Ingberg, chief of the Fire Resistance Section, made these studies.
