For Intervallet 800—900 Favne haves kun en Ob- 

 servation. 



De her fundne Hastigheder slutter sit; meget godt til 

 de ovenfor fundne. etter hvilke Grjenneinsnitshastigheden 

 mellem og 100 Favne er 1.82 og mellem 100 og 200 

 Favne 1.28. Man ser endvidere, at Loddets Hastighed er 

 stadig aftageude med Dybden. [Jdjevner man paa grafisk 

 Vej Hastighederne i tien første Tabel og slutter denne 

 iuekke til den anden, der beror paa tiere Iagttagelser. saa- 

 ledes at Tidsintervallerne i den sidste beholdes, saa faar 

 man et Billede af Rorloddets Bevægelse saaledes som Kur- 

 verne il i Fig. 15 og 10 viser. Fig. 15 viser de til de 

 forskjellide Tider udlobne Længdér al' Lodlinen, og Fig. 16 



For the 800 — 900-fathom interval w.e have only one 

 observation. 



'1 he velocities tims determined agree pretty well with 

 those previously found. which average 1.88 between and 

 100 fathoms and 1.28 between loo and 200 fathoms. 

 Moreover. the rate of descent decreases steadily with the 

 depth. Now, if we equalize, in a diagrammatic form, the 

 velocities given in the tirst , Table, and adjust that series to 

 the second, retaining the time-intervals of the latter, as 

 based on a greater number of observations, we shall have 

 figured before us the descent of the tube-lead, as repre- 

 sented by the curves R. R, in Figs. 15 aud 16. Fig 15 

 shows the lengths of sounding-line run nut during succes-
