average length is greater, as can be seen from the accompanying measurements of young 

 eels from the west coast of Jutland made under Dr. A. C. Johansen's direction in the 

 summer of 1905.

found. Nor do the photographs of the developmental series on my PI. VIII give the correct picture of the 

 relation between tha lengths of the different developmental stages; for example, the specimens figured in Fig. 7 — 8 

 were as it happened small, Fig. 9 again large (on account of individual variation, just as one man may be 

 taller than another).
