Table 24 h (continued ).- 



Change of topographic charts of isobar ic surfaces into isobar ic 

 charts in level surfaces. 



Example: Given the topographical chart of the 600 d-bars surface. Required the isobaric 



chart in 600 dynamic meters depth. 

 Table VI B shows the curve of 61S d-bars to be identical with the 582.548 dynamic meters 



curve, the curve of 618. 1 d-bars to be identical with the 5S2.454 dynamic meters curve, 



and so on.
