 of its Visiting Committee, who have personally donated the sum

 by meeting the heavy costs of completing the exhibition geologi-

 field. Mr. R. A. F. Penrose kindly subscribed the sum of $50 

 for the purchase of special books.

 one Sauveur metallographic microscope and one Zeiss vertical 

 illuminator. Messrs. Phelps, Dodge and company, New York, 

 have donated one petrographic microscope. The plant in economic 

 geology has been further increased by appropriations from the 

 Secondary enrichment investigation fund, to the extent of $718 

 expended for office and field equipment and $59 expended for 

 thin sections.
