One could try to find through extrapolation the form of 

 the curve, that would represent the relation between 

 température and rate of assimilation at higher tempe- 

 ratures when noxious influences could be avoided. However 

 we hâve given up this extrapolation, partly because we

think the numbers obtained somewhat uncertain (a greater 

 quantity of numbers, from which an average could be 

 taken would be necessary), partly because we are convin- 

 ced that in our experiments we did not détermine the 

 relation between the actual velocity of assimilation and 

 the température.
