XIV. PROCEEDINGS LIVERPOOL BIOLOGICAL SOCIETY. 



2. Dr. W. H. Gaskell, F.B.S., Cambridge, delivered a 

 lecture on "The Lamprey and its Transformation." 

 The lecturer first of all sketched out in a most 

 interesting manner the changes undergone by the 

 larval Ammoccetes before its final metamorphoses 

 into the adult Lamprey, and traced out a wonder- 

 ful series of resemblances between structures found 

 in Limulus — the King-Crab — and in certain stages 

 of the development of the Lamprey. The lecture 

 was listened to with great interest by a large 

 audience, and the Society is to be congratulated 

 in having the opportunity of hearing from Dr. 

 Gaskell's lips an account of his work on the evolu- 

 tion of the Yertebrata. An animated discussion 

 followed, in which Profs. Sherrington, Herdman, 

 and Paterson, and Dr. Klein and Mr. Cole took 

 part. A cordial vote of thanks was passed to 

 Dr. Gaskell. 



The seventh meeting of the twelfth session was held at 

 University College on Friday, May 13th, 1898. The 

 President in the chair. 



1. Prof. Sherrington demonstrated a series of micro- 



scopical preparations of Sensorial End Organs, 

 and Mr. I. C. Thompson exhibited specimens of 

 the Alga (Trichodesmium erythrceum) . 



2. A note on "A Tetramerous Specimen of Echinus 



escidentus" by Mr. H. C. Chadwick, was com- 

 municated by the Hon. Secretary (see "Transac- 

 tions," p. 288).
