face-current pressed in under the ice, and becoming thinner and 

 thinner the farther it forces its way. It seems to me most 

 probable, however, that the differences, to some extent at least, 

 are due to a change with time; for the current might have 

 been driven to its greatest velocity at about 2 p. m., and then 

 have decreased with the going down of the wind, or even stopped 

 on account of the altered direction of the wind. 



On the following day, the 14th April, a continual easterly 

 wind was blowing, although somewhat gentler than on the 13th, 

 and as the last observations indicated currents of tolerable regu- 

 larity even in greater depths, I decided on that day to attempt 

 especially to study these deep currents. The attempt was also 

 successful, and a decided deep current was found to flow here, 

 but nevertheless with sometimes most capricious changes. As 

 these may render a complete graphical representation difficult, 

 the tables of that morning are also introduced here.
