The observations of Dr. Otto Hermes, director of the Berlin Aquarium, who has recently dis. 

 covered the true nature of the organ of Syrski in the Conger, are extremely interesting: 



"Since S.vrski, in 1874, found the organs in Anguilla vulyariit which are called by his name 

 and which, by him and most zoologists, were taken for the male reproductive organs it is only
