[Describes the male and female organs, and calls attention to the paper of 

 Duvemoy, who, in his judgment, described correctly the ruffle-like or male 

 tj-pe of the genitalia of the eel. Excej)t for this, the paper is, like those 

 of Dareste, Cattie, and others, simply a confirmation and extension of pre- 

 vious observations.]

["On the reproduction of the eel." States the fact that, according to 

 the observations of Upper Fishmaster Dalkner, the eels taken from August 

 to November (especially in September and October) in the Baltic along the 

 Flensburg-Alsen coast and in the Lesser Belt were apparently migrating 

 from the south to the north, this being indicated by the manner in which 

 the leaders of the eel-pots were attached — to wit, to the northern wing of 

 the eel-pot.]

Deutscher Fischerei-Verein, i, 1881, Jan. 31, pp. 20-21. 



["On the propagation of young eels." An argument in favor of select- 

 ing for transplanting into land-locked waters eels between one and two 

 years of age, rather than the miniature fish usually used for that purpose. ]
