Fig. 9. — Chart of pulse rate and arterial pressure from a case of arterial sclerosis, 
cardiac hypertrophy, and interstitial nephritis. It shows a continuous high 
pressure in spite of all measures adopted. The record gives the figures every 
fifth day at 11 a.m. from 13th September to 17th November. The crosses give 
the pressure and the dots the rate. 
Fig. 10. — Chart of pulse rate and arterial pressure from a case of Addison’s disease. 
The employment of adrenalin caused a temporary rise of pressure, and later an 
increase of rate, but after a fortnight it ceased to produce these effects, and the 
patient gradually sank and died. The pressure is recorded every second day, 
taken about 11 a.m., from 1st to 27th October.
