Philadelphia, December 27th, 1880. 

 To the Director of the Mineralogical and Geological Section : 



The mineral collection of the Academy has been improved 

 during the past year by the addition of the usual number of dona- 

 tions. These have been carefully labeled and placed in the cases 

 b}^ Mr. Charles F. Parker, to whose industry and care we are 

 chiefly indebted for the satisfactory arrangement and labeling of 

 all our specimens. I submit with this a list of the donations 

 during the past year. The collection is in a satisfactory con- 

 dition.
