Figure 13 represents the relationship between M, M(l), MCp^^^) 

 and V, respectively, where for comparison the "Austausch coefficients" 

 or "Koeff izienten der Scheinreibung" are plotted, as given by A. 

 Defant in "Dynamische OzeanOgraphie" (p. 76) or by Sverdrup, John- 

 son and Fleming in "The Oceans," according to the results of H. 

 Thorade and W. Schmidt. These values show a rather good agreement 

 with the curve for M, that means with formula (36). Only for strong 

 winds are the values given by Thorade and Schmidt somewhat lower 

 than the M-values given by (36). Their numerical values are between 

 M and M(l), and this probably indicates that at very strong winds 

 the stage of fully developed sea was not attained in all cases, when 

 the observations for the determination of the "Austausch-Koeff izien- 

 ten" by Schmidt or Thorade were taken. As an example of the in- 

 crease of the coefficient of eddy viscosity with rising sea. Table 

 4 shows the M(p) values at a wind velocity of v = 10 m/sec as a 

 function of increasing "wave age" p.
