Conditions similar to those at Stat. II were also observable 

 at Stat, V later in the same afternoon (PI. XIX, figs. 14 to 17) — 

 great changes in the current at a depth of 1'4 metres, and rela- 

 tively stationary currents above and below. The latter here flow, 

 however, in the opposite direction to those at Stat. II. It is 

 conceivable that this is due to a continued slow change in the 

 surface-current from noon to 5 p. m. ; but this is rendered im- 

 probable by the remarkable fact that invariably the surface-cur- 

 rent at a depth of 0"5 m. was found to flow S. by SSW. at 

 Stat. II, but at the outer stations always N. by NE. 



The observations of the following day give a clear instance 

 of this, as on that day observations were made at all the sta-
