GERM - CELLS 



WITH SPECIAL REFERFNCE TO THE RECENT RESEARCHES OF 



Dr. JOHN BEARD, 



University Lecturer in Comparative Embryology, Edinburgh. 



This paper is an attempt to summarize the recent 

 researches of Dr. Beard on Germ -cells, and the many problems 

 related thereto. Although of necessity brief, it may be 

 regarded — so far as it goes — as representing his views. 



The paper when read was illustrated by means of a number 

 of lantern - slides — diagrams and photographs ; and at the 

 conversazione afterwards a number of micro -preparations 

 showing germ -cells in various phases of wandering were 

 exhibited. Both lantern and micro-slides were kindly lent for 

 the purpose by Dr. Beard. 



I am indebted to Dr. Beard for his great kindness in 

 revising and correcting the proof-sheets, and for the loan of 

 the plates of illustrations ; and I wish here most heartily to 

 thank him for his very kind and generous help. 



W. T. HAVDON.
