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 Anatidte 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 bii;ds, 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. Many specimens of interest were secured during the 
year, the most important being the Van cler 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.
