Individual seated. Moderate inspiration. formulas H equals weight of heart in grams,\\, weight of body in kilograms, V, volumeof heart in cubic centimeters, A, area ofsilhouette in square centimeters. Theabove formulae express heart size in female heart is about 5 per cent lessin size for a given body weight. 2. For a given height and age there is anaverage or typical body weight. The typi-cal heart size is correlated with this typicalbody weight and hence may be correlatedwith the stature corresponding with thisweight at a given age. Typical statures fora given body weight at a given age aretables referred to above,heights are based on thestatistics available at thetime the table was prepared. More recentdata suggest inconsequential changes inthese estimates. Individuals tall for weightand age may be expected to have somewhat given in theThese typicalheight weight. Fig. 4.
