mounted progressively, from 0-085 ^o 0-175. Therefore I had 

 to find a correcting factor which increased in proportion as 

 the wound diminished. 



On second thought, this was logical, for I already knew 

 from a number of experiments that the most important factor

in the rate of cicatrization was the size. Now, in our example, 

 formula (2) was established for a wound of a certain dimension: 

 i6-2 cm.-. At the end of twenty days its size was reduced to 

 I cm.-. It was therefore obvious that the first formula could 

 no longer be considered as valid. The correcting factor had 

 to be a function of the actual area of the wound; and as this
