A method is described for determining one and only one parameter governing the refraction effect of levelling. The central idea is that this parameter is determined not by (temperature) measurements during the observation but by adding one more element in the Least Squares Adjustment of the levelling network.

Furthermore is described an experiment where it was found that this parameter differed significantly from zero and a tentative first value is suggested.
