PREFACE. 



as regards the methodical treatment ; the work itself has been carried 

 on by Hungary alone without any interruption. 



It is perhaps still a question of the earnestness and dignity of Orni- 

 thology as a branch of Science, whether, amidst the enormous progress 

 attained in all departments of Science, the phenomenon of Migration, 

 which is of such eminence in Ornithology, should be treated henceforth 

 too rather as a pastime, and whether it shall remain in future also a 

 field for sentences, quite out of keeping with the present state of 

 Science ? 



In recommending my essay to the attention of the British Ornitho- 

 logists' Union, I hope that the followers of Derham, who two hundred 

 years ago (1708) worked as pioneer in Ornithophaenology, will find 

 ways and means of initiating better proceedings, especially as regards 

 a methodical treatment of the results of the observations.
