510 PROCEEDINGS OF THE ACADEMY OF [1898. 



Fifteen half-upright cases were purchased duriDg the year, in 

 which it is intended to arrange the dried specimens of Lower Inver- 

 brates, the duplicates being stored in closets, which have been pro- 

 vided underneath the cases. Part of this transfer has been already 

 accomplished and when completed it will permit the removal of the 

 remaining wall cases where the Invertebrata have been stored 

 heretofore. 



Two new museum cases have been placed in position on the mam- 

 mal floor in which are arranged the higher Quadrumana and 

 Carnivora. One of these was provided through the Mary Jeanes 

 Fund, established this year by Anna T. Jeanes for general museum 

 purposes. The fund will enable us to make much more progress in 

 future in furnishing the new building and in accommodating our 

 rapidly increasing collection. Another improvement in the Mammal 

 department has been the placing on exhibition of the Pacific Walrus 

 obtained by Dr. Sharp and Mr. J. M. Justice. 



In the Archseological Department Mr. Clarence B. Moore has 

 presented an upright case for the reception of some of the material 

 which he has added to the Moore Collection during the year. Mr. 

 Johnson has continued to devote much time to the arrangement of 

 the Isaac Lea Eocene Collection, which has been largely increased 

 during the year through the liberality of the Rev. Dr. L. T. Cham- 

 berlain. This collection now occupies four large double mahogany 

 cases contributed by Dr. Chamberlain, and is undoubtedly the most 

 complete and important series of American Eocene mollusca in 

 existence, while it also contains the largest series in America of 

 European Eocene shells. Mr. Johnson has also been engaged to 

 re-arrange the Academy's series of Tertiary Invertebrates. 



In the Botanical rooms a series of nine cases has been erected for 

 the accommodation of the herbarium, which has outgrown its old 

 quarters. 



Temporary cases have also been fitted up in the Ornithological 

 room for skins of large birds. Much time has been devoted by the 

 several Conservators to the care of the specimens in their special 

 departments. 



The Curators regret to have to report that much damage was done 

 to furniture and material stored in the basement by the severe flood 

 of August 3rd. The extraordinary rainfall flooded the city sewers 

 and filled the streets to the depth of eighteen inches, from which it 

 forced a way into the cellars and basement. The damage has, how-
