been arranged in systematic order. Many cases of large birds formerly 

 stored elsewhere have been placed in their proper position, so that the 

 entire study series of birds is now for the first time brought together 

 where it is readily accessible. 



Mr. Rehn finished the cataloguing and relabelling of the Tristram 

 collection during the year, and this material, numbering 6,180 skins, 

 together with several smaller collections, has been distributed in the 

 general series. 



Ten large wooden cabinets were secured for the accommodation 

 of the AnatidiB and other large birds formerly arranged in temporary 

 cases. 



The labelling of the mounted birds was resumed early in the year, 

 and all the specimens, with the exception of the song birds, are now 

 labelled with technical and vernacular names and locality. Owing to 

 the alterations to the building some of the exhibition cases had to be 

 taken down or altered, so that the collection has been temporarily 

 disarranged, but the erection of new cases will soon permit of their 

 proper display. j\Iany specimens of interest were secured during the 

 year, the most important being the Van der Pol collection of East 

 Indian birds, comprising 1.070 specimens, representing many species 

 not heretofore in the Academy's collection. 



The Delaware Valley Ornithological Club and the Pennsylvania 

 Audubon Society have continued to hold their meetings in the building 

 and have done much to maintain activity in this department. In 

 December, 1907, the American Ornithologists' Union held its twenty- 

 fifth annual meeting at the Academy, which in point of attendance 

 and interest was the most successful ever held.
