Lorenzinian ampullae and tlu'ir nerve supply in Torpedo. Ihe Loren- 

 zinian ami)ullae are honiolotrous with the "terminal buds" of other au- 

 thors. There are no "pit origans'" in Torpedo . There is no genetic re. 

 lation between the ampullae and the lateral line organs. There is no 

 morjihologic distinction between the lateral line and the organs of 

 Savi. The latter are mere modifications of the former.

The author has emplo\ed the method of isolating the nerves in 

 early embryonic stages and studying them in teased preparations. 

 This procedure gives important data on structures the nature of which 

 in section is more or less doubtful. The j)aper strongly supports the 

 theory of Hi.>^. The nerve fiber unites with the muscle before the de- 

 velopment of the sarcolemma, which becomes so intimatelv fused with 

 the sheath of Schw.\nn that the boundary between the two structures 

 is indistinguishable. G. e. c.
