and another large one for Ungulates through the Mary Jeanes 

 Fund, while another case of similar character has been presented by 

 Dr. Francis W. Lewis for the reception of birds on the upper floor. 



Four large storage cases have been j)rovided for mammal skins, 

 and placed on the fifth floor of the new building. 



In the department of Archaeology, Mr. Clarence B. Moore has 

 presented one upright mahogany case with plate-glass sides and 

 shelves, and one horizontal case for the accommodation of his 

 rapidly increasing collection, and Dr. Dixon has provided a show- 

 case for the display of certain human remains. 



Besides these additions, considerable work has been done in 

 improving the building, the entire vestibule on Race street having 

 been repainted, and the lavatories all completely renovated, and 

 modern flttings introduced. 



Through the liberality of jNIr. Clarence B. jNIoore, our museum 

 has, for the first time in its history, been thrown open to the public 

 on Sundays between the hours of one and five o'clock. This inno- 

 vation has met with popular approval, the attendance of visitors 

 being very large, and composed mainly of persons who would 

 otherwise have been unable to view the collections. 



The progress in adding to, rearranging, classifying, labelling and 

 caring for the collections during the year has been satisfactory. 



The Conservators of the several Sections have devoted much time 

 to the care and classification of the specimens in their respective 

 departments. Valuable work has been perfox*med by Dr. H. A. 

 Pilsbry in the Conchological ; by Messrs. Thomas Meehan and 

 Stewardson Brown in the Botanical ; by Dr. Henry Skinner, Dr. 

 Philip P. Calvei-t and ]Mr. Charles Liebeck in the Entomological, 

 and Messrs. Lewis Woolman and Theodore D. Rand in the 

 Geological departments. 



Rev. L. T. Chamberlain, special Curator of the Isaac Lea col- 

 lection of Eocene Mollusca, has continued to add valuable mate- 

 rial during the year, bringing the total number of entries up to 

 5,161. Dr. Chamberlain has now enlarged the scope of the col- 

 lection to include the Oligoceue. About one hundred and sixty 

 species from the Vicksburg and Red Bluft' horizons have been 

 already incorporated, while much foreign Oligocene material, 

 not yet labelled, is on hand. He proposes to send a collector 

 to the principal exposures to procure new material. Mr. C. W.
