' O. T. Gronlie gives in his text [1914, p. 224] values (between 1.35 and 1.77 per mille» 

 of these gradients for the region between Andoi and Skjervoi, which are much higher 

 than those computed from Helland's observations ; but as far as I can see Gronlie must 

 have made some strange mistakes in his distances. His map of the isobases gives 

 much the same gradients as Helland's observations. 



2 As will be mentioned later (p. 263I it seems to me that Tanner has probably mistaken 

 his level h in this region, and I have used his highest terraces for the computation 

 of the gradient.
