The use of the abdominal belt to control the vomiting of pertussis has long passed the experimental stage. In my own series of cases, now numbering 43, in which the belt has been used, the results have been surprisingly good. It occurred to me that the results obtained in my own cases possibly were not shared by the profession in general. I, therefore, sent the following circular letter to many of the leading pediatrists of the United States, and it is to a study of the results obtained in so doing that I ask your attention for a few moments.
