INFLUENCE OF SIZE OF WOUND

 finally led me to admit that the correction could be satis-

factorily expressed by which it sufficed to subtract from 



formula (4). It may be of interest to give the reader a few 

 figures enabling him to realize that the accord thus obtained is 

 quite satisfactory. (Patient no. 409) Fig. 22 represents the 

 successive aspects of the wound. The table below gives the 

 figures. 



The formula for ordinary wounds gave March 31st as the 

 date of total cicatrization, or an error of ten days. 

 The corrected general formula, which became

possessed the advantage of admitting a zero, whereas the 

 current formula, being asymptotic, forced one to admit that 

 the wound was cicatrized when the calculation gave a figure 

 inferior to 0-4 cm.^ for example. 

 What is more, the correction is so slight for wounds in 



which the ratio - is small (it is never inferior to i) that it can 



be introduced at any moment, as soon as it is observed that
