624 PROCEEDINGS OF THE ACADEMY OF [Dec, 



year in cataloguing and distributing the mounted plants that have 

 accumulated during the period of Mr. Brown's illness and has dis- 

 posed of the greater part of them. 



Dr. Witmer Stone and Mr. Van Pelt have resorted the packages 

 of plants in the Porter collection and arranged them temporarily 

 in the 40 new metal cases provided by the State appropriation, 

 placing them in systematic order, so that they may be easily con- 

 sulted. Messrs. Long and Van Pelt have gone critically over several 

 of the orders, separating the local material and duplicates. 



A number of botanists have consulted the herbarium during the 

 year and specimens were loaned to J. M. Greenman, M. L. Fernald, 

 K. K. McKenzie, Agnes Chase, Harold St. John, and E. S. Steele. 



Minerals and Rocks. 



From the State appropriation six new oak and plate-glass table 

 cases were secured for the William S. Vaux collection of minerals 

 and ten others were purchased from the William S. Vaux Fund. 

 These have been substituted for the old cases, and Mr. Samuel G. 

 Gordon, a student on the Jessup Fund, has cleansed the entire 

 collection, after which he assisted Mr. F. J. Keeley, curator of the 

 department, in selecting a series for exhibition. These were arranged 

 according to the sixth edition of Dana's System. The relabelling 

 of the collection will be undertaken at once. 



The duplicates have been arranged on trays in closets immediately 

 under the exhibition series, while the Academy's collection of minerals 

 is arranged in the lower part of the closets, following the same sys- 

 tematic arrangement. Thus for the first time all the general 

 collections of minerals are brought together. 



The meteorites, representing about 60 falls, are arranged in glass 

 cases in the entrance hall, while the local collection of minerals has 

 been removed to the first floor of the museum just beyond, where 

 it is arranged by Mr. Gordon in some of the old Vaux cases. Numer- 

 ous small collections received from time to time have been gone over 

 critically and specimens of value picked out, while the duplicates 

 have been made up into sets for schools and other institutions. 



Mr. Gordon made a field trip through Franklin and Adams Coun- 

 ties, Pennsylvania, during the summer and secured a valuable 

 series of volcanic rocks. 



Archaeology. 



From the State appropriation two horizontal and five upright 

 exhibition cases have been provided and one mummy case. This
