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 parthenogenetically. 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 Daphnidae. I propose to publish a more detailed 

 account in a future paper.
