CICATRIZATION OF WOUNDS

 them from the values of i found in the chart. The study and 

 discussion of the two coefficients would require too much 

 space and I therefore refer the reader to the original paper. ^

 FIG. 23. CORRECTING FACTOR IN EQUATION (6) 



The concordance between the curves calculated by the extra- 

 polation formula (4) and those obtained by the exponential 

 equation (6) is excellent, as shown by the table below. 



But there is another advantage in employing this equation. 

 It may be remembered that the phenomenon of reparation is 

 due to a double process. First, contraction and second, 

 epidermization. The two formulae, (4) and (6), translate into 

 mathematical language the result due to the combined 

 mechanisms. It would be too long and fatiguing for the
