NOTE. 



IT is of considerable importance for. the proper appreciation of 

 the views advanced in the present essay, to ascertain whether a 

 polar body is or is not expelled from eggs which develope partheno- 

 genetically. I wish therefore to briefly state that I have recently 

 succeeded in proving the formation of a polar body of distinctly 

 cellular structure in the summer-eggs of Dapknidae. I propose to 

 publish a more detailed account in a future paper.
