Nansen have endeavoured to relegate their origin and governance. Closer examination 
of the question, however, reveals great difficulties also here. According to these writers’ 
theory, the quantity of liver (and roe) in Lofoten, varies according to the temperature 
of the Sognefjord section for the previous year, whereas in the North Sea and Romsdal 
waters, it corresponds to that for the same year. This theory naturally leads us

to examine the statements in the fishery statisties as to the quantity of liver obtained 
from the skrei in different years in various parts of the Norwegian coastal waters. This 
I have done, as will be seen in Fig. 115, where the curves show the quantity] of liver ob- 
tained in each district from Romsdal to Tromso, in the years 1900—1911. It will be 
noticed that all the curves coincide as nearly as could possibly be expected, from which 
we may conclude, that the fluctuations in the quantity of liver obtained along the 
whole of the northern coast of Norway are simultaneous, and of like direction and degree. 
This observation is not new; merchants trading in oil have, to my knowledge, long
