Great Belt. The growth of the 0-group in 1903 has been foUowed by the aid of 

 many measurements, which are given in Tab. C. This Table is constructed in 

 the same way as Tab. D and shows the growth of the 0-group throughout the year. 

 A comparison of Tables C and D shows, that the growth of the 0-group in each 

 month is almost the same in 1903 as in 1904 (Tab. B, p 28 shows the same 

 for 1902). 



If the three lists B — D are taken together, it is seeu that in none of the 



Tab. D. List of measurements of cod (0—20 cm-), 1904. 



years these represent, 1902 — 04, is there any indication of a year's group under 

 ca. 8 cm. in the autumn, or between the pelagic young and ca. 10 cm. in the 

 spring. The group of ca. 10—20 cm., which appears distinctly in February — March 

 in all three lists, is thus I group. We can therefore conclude from the three 

 Tables, that tlie cod young reach a levytli of ca. 10 — 20 cm. in the course of a 

 year, and that the growth takes place chiefly in the months June — October.
