Fio. 29.—Diagrammatic section of Erlangers at position IN. Above and below the vertical median section of stop-cock are horizontal sections,the upper at level of tube E, the lower at level of tube F. (From Dr. Erlangeradrawing.) to influence the trace caused by the rapid pressure variationsof the pulse-wave. When the pointer is set at In, as inFig. 28, the stop-cock makes the connection shown in Fig. 29. SYSTOLIC AND DIASTOLIC MEASUREMENTS 97 The manometer, armlet, and pressure space (PS), inside therubber bulb (B), are in circuit, through the tube (F), with theinflator attached to the tube In. The air within the glassbulb (G) which communicates with the tambour, marked T S(tambour space), is open freely to the exterior through thetube (E), which connects with a vertical bore in the center ofthe stop-cock (C). Thus, as the pressure in the apparatus is.
