    The liver tracing shows practically the same features as the venous (Fig. 144), except that the auricular depression is more marked, and in consequence there is an absence of the first part of the ventricular wave. Next day the pulse had become very rapid, and both jugular and liver pulses presented characters similar to Fig. 142. On the 27th July the pulse was quieter, and the auricular and ventricular waves appear separate again, the highest wave being broader, and bearing two small waves separated by a slight depression, signifying, probably, the time of the closure of the pulmonary valves. Tills patient’s pulse hitherto had been always regular, but it so happened on the 23rd of June, when Fig. 145 was taken, while the patient was holding her breath, in order to facilitate the taking of a tracing of the liver pulse, there occurred a few beats presenting the Fig. 144.—Simultaiieoius tracings of liver aird radial pidses (Case 46).

The liver pulse is not very evident, but it can be observed that it maintained its wonted rhythm during the period of irregularity of the radial pulse. On 30th June the patient’s condition had become very serious. She suffered from great dis- tress m breathing, with pain in the abdomen. The respirations were 52 per minute, there was in- cessant cough and bloody expectoration. There was dulness of the base of the left lung, accompanied by tubular breathing, and numerous moist rales. The pulse was 100,and the jugular pulse presented featimes similar to those seen in Fig. 144, except that the auricular wave disappeared during each respiration (Fig. 146).

There are also changes in the radial pulse. Pidse 100 ; respiration 51 per minute (Case 46).
