ILLUSTRATIONS 



Plate I 

 The sphygmomanometer. 



Plate II 



Fig. 1. Record 184. Coincidence of the three criteria used in reading sys- 

 tolic pressure. 



2. Records 717 and 720. The first crosses mark the points where the 



systolic pressure is read — sudden increase in amplitude of oscilla- 

 tions. The second crosses mark the points where diastolic pres- 

 sure is read. 



3. Record 190. The cross marks the point where there is a marked 



increase in amplitude of oscillation followed by marked separation 

 of the limbs in the next pulse wave. 



Plate III 



Fig. 1. Record 259. Appearance of separation of the limbs ahead of the 

 marked increase in amplitude. 



2. Two records where the systolic pressure cannot be read. 



3. Records 533 and 648. Each of criteria (a) and (c) appear more 



than once.
