has always hitherto been accorded to it, and, further, tliat I 

 may personally continue to enjoy the same friendship with 

 the numerous contributors which it has been my good fortune 

 to experience throughout the long course of the Journal's 

 existence. 



In conclusion, I must not fail to state how much I have 

 been indebted to ray Co-P]ditors, and especially to my dear 

 friends the late Prof. Arthur Henfrey and Dr. J. E. Gray, 

 and to my present colleagues, Dr. Giinther and W. S. Dallas — 

 to the latter especially, who had taken a most active part in 

 superintending the publication for many years before his 

 name appeared on the Titlepage. 



WILLIAM FRANCIS.
