Figs. 60 to 63 give the central vector-diagrams of the relative movements 

 at the various depths, as far as they could be constructed. They diflfer 

 gready from the vector-diagrams of the relative movements at Stat. 41

I have also made an attempt. Fig. 64, to construct progressive vector- 

 diagrams for the relative movements at the various depths, between r.oo

 nimierous to give trustworthy curves, and our figure may therefore only 

 be considered as an approximate experiment It shows, however, that there 

 must have ben a striking difference between the movements at this place 

 (Stat. 20) and those at Stat. 41. This diflference may to some extent be 

 explained by the different situadon. Stat 20 being to the south-west of
