Here isa diagram of growth, (Fig. 32), which represents, asaccurately as I could determine it, the curve completefor man from birth up to the age of forty years. THE RATE OF GROWTH 99 It has been calculated by a simple mathematical pro-cess where these ten-per-cent. increments fall, andfrom each point in this curve where there has beensuch an increment, a vertical line has been drawn, asyou see here. These lines are very close together atthe start. One ten per cent, after another follows ina short interval of time, but gradually the time, as as^yrs 30^rs ^^yrs 30 A iZO / /| / •00 12 yr^-25- 77 62 lbs / / / ao r / / 7 60 20 lbs. y / 40 3yrs ^ y 15 A 20 -10 A / m 0 Fig. 32.
