(3) The weight of the heart can be deduced from the weight of the body and 
that of the kidneys by means of a linear equation with an average error of about 
eight per cent. 
(4) The weight of the body and that of the kidneys ought always to be con- 
sidered before deciding whether a given heart is abnormally large or small. 
(5) It is doubtful whether the weight of the heart is sensibly con-elated with 
age in an adult population (of ages 25 — 55). 
(6) The weight of the brain is less closeky associated with the body weight and 
that of other viscera than is the heart weight.
