Recently we wished to construct a replica of a bronchus of the first order compromised by carcinoma. This was to form part of an educational exhibit of bronchogenic carcinomas at the annual session of the American Medical Association. As we did not wish to resort to the frequently used moulage process, we fashioned a bronchus in rubber, molded into it an irregular mass resembling carcinoma and painted the whole model with appropriate colors. A machine was then constructed which would make the bronchus expand and contract as it does in life, so that a view through a bronchoscope inserted into the bronchus through a dummy head would give a realistic illusion of seeing a bronchogenic carcinoma in a living patient. This was enhanced perhaps by an inspiratory and expiratory surge of 500 cc. of air, representing tidal air, eighteen times a minute.
