Station G2 differs slightly from the remainder, inasmuch as we here find a greater 

 number of newly spawned eggs than was to be expected. Evidently, the current must 

 have brought down the newly spawned ^gs from the banks southwest of the station. 

 The current at this spot can at times be very strong, and in this very direction. The 

 numbers, however, both at stations 62 and 61, are not sufficiently great to furnish an 

 exact picture of the stock there. 



The curve for the later stages (III) shows throughout what might theoretically 

 have been expected, the later stages themselves being proportionately fewest where 

 most eggs were found. The curve rises as we move away from the spawning banks, 

 as far as station 62, falling again over towards the land, thus indicating that we are 

 once more approaching grounds where, in some slight degree, spawning takes place. 



As we have seen, the proportion between the different stages varies greatly at 

 different places, even for samples taken on one and the same day; the variation is, 

 however, sufficiently regular to permit of our forming some opinion as to the cause. 

 The example here shown is taken from a locality where the contrast is marked; great 

 quantities of cod spawning within a restricted area, close to the very deep water 

 where cod never spawn, but in which a certain quantity of eggs may be found, having 

 been carried thither by the current. A different state of things would necessarily be 

 encountered where the spawning takes place sparsely over areas of wide extent, espe- 

 cially if forming part of a restricted region of sea; at such places, there would never 

 be the great difference between the relative frequency of the stages at the various 

 stations. 



Stations 64-65 and ()6 were also previously investigated, viz.: 25 '2-12 '?> and 29/3. 

 Not until the last-mentioned date however, were cod eggs found in great numbers; the 

 principal spawning was then just commencing. At these three stations (30-31-32) 

 (29/3) we find the following yield for the different stages (here stated in %).

The principal spawning this time takes place farther in on the banks; we find, 

 however, again the same feature as before noted; where the eggs are found in
