Dr. Jarre has had the procedure in mind for several years, but, only recently, our desire to record, if possible, changes in contour and size of the tracheobronchial tree during respiration, has led to the development of the apparatus which Dr. Jarre named the "Cin-ex camera." We have endeavored to make successive records of functional changes at such short intervals as would enable us to interpret the motor phenomena themselves rather than to produce a true moving picture. The apparatus, together with some of the studies conducted up to that time, was presented to the staff of the Grace Hospital and the Detroit Roentgen-Ray Society on April 19, 1929, and will be described in detail in the roentgenologic literature.
