The ratio between heart volume calculated from heart weight 

 in bodies studied in the anatomical laboratory and the meas- 

 ured heart volume is shown in table 19. The hearts are grouped 

 according to the extent of divergence of the observed from the 

 calculated volume. Those showing less than 2^ per cent of 

 divergence are grouped together. The rest are grouped accord- 

 ing to the nearest 5, 10, 15, 20, 25, 30, 35 and 45 per cent of 



TABLE 19 



Hearts from cadavers grouped according to -percentage of divergence from the assumed 



ratio between empty heart volume and diastolic volume 



positive or negative divergence. Separate columns show the 

 number of males and females in each group, the extremes of 

 heart volume (including contents of chambers) and the average 

 per cent of divergence from the 'normal' heart weight-body 

 weight ratio of those of each group for which records were 

 preserved. 



From this table it may be seen that while the greatest number 

 (10) of hearts fall within the group assumed to show normal
