Table 4 gives the locations and values of the first few extrema. East of the 

 main current there is a countercurrent of the magnitude exp ( — tt/^S), or 

 17 per cent of that of the main current. From the analyses of actual data 

 by Wiist (1936) and Isehn (1936) it appears that this theoretical counter- 

 current is very nearly equal to that observed. In Chapter VIII it is sug-

 exaggerated relative to the scale for the western solution. From Munk (1950,

gested that the Gulf Stream is not essentially a frictional phenomenon. 

 Frictionless models are described, but none give the remarkable similarity 

 to the countercurrent which the Munk theory yields.
