20. Reichenow on the Progress of Ornithology. 



[Ueber die Fortscliritte und den gegenwartigen Stand der Ornitho- 

 logie. ErofFiiungsdrede zum V. Internationalen Ornithologen-Kongress, 

 Berlin, 1910. \'on Aut. Reichenow, President des Congreeses. Berlin, 

 1910.] 



No one could have been found more worthy of the Presi- 

 dential chair at the Fifth International Congress of Ornitho- 

 logists than Professor Reichenow, and we were all heartily- 

 glad when we heard that he had managed to overcome the 

 difficulties that he anticipated when he was unanimously 

 nominated for that post at the previous meeting. Of the 

 successful issue of the Congress at Berlin, in May 1910, we 

 have already given a general account*, but the volume con- 

 taining the full text of the Presidential Address, and the 

 papers read at that meeting, has only just ajjpeared. 



T>r. Keichcnow's Address is to be recommended in every 

 way as a masterly sketch of the j)ast history and the 

 present state of Ornithological science. Bcginrnng with 

 Linnseus, he specifies the principal advances that have been 

 made in our knowledge of the Class of Birds during the past 

 150 years. Every one of the numerous branches into which 

 Ornithology is now divided, even the bearing of our science 

 on what is called " Aviation,"" is taken in turn. We will 

 not go into particulars on the present occasion, but strongly 

 advise all who are interested in the study of Bird-life and 

 Bird-structure to make themselves acquainted with Professor 

 Reichenow's excellent address. They will not fail to be 

 instructed.
