It is witli the greatest regret that I find myself obliged to re- 

 linquish the Editorship of this Journal, after having been associated 

 with it for more than eleven years. 



My interest in the Journal and the subjects which it was 

 founded to promote, remains as great as it was in 1878, but other 

 duties have now absorbed the hours of the night which were formerly 

 reserved for the Journal, and have left me no time for even a limited 

 amount of supervision. 



Whilst I shall no longer have any official connection with the 



Journal, I shall still, I hope, be able to watch over its interests, and 



I have every confidence that under the care of my former colleagues 



in the Editorship it will maintain the reputation it has obtained, 



and will continue to be recognized as an indispensable guide to the 



ever-increasing mass of periodical literature relating to Biology and 



Microscopy.
